THE QUADCOPTER REVOLUTION
The emergence and proliferation of quadcopter technology has blown traditional remote controlled helicopters into a tailspin. As RC enthusiasts and developer of both helicopter and multicopters, we have never witnessed a more dramatic shift in demographics and consumption. Harnessing decades of advanced helicopter technology, quadcopters have overtaken the traditional RC helicopter market in recreational and more noticeably in professional applications. To unravel some of the mystery of this transition is to understand the basic differences of helicopters and quadcopters.

QUADCOPTERS VERSUS HELICOPTERS
The equivalent of hybrid helicopters, quadcopters are designed to combine the agility and wind resistance of collective pitched helicopters with the stability of pilot friendly co-axial (double layer rotors) helicopters. Pilot level required for collective pitch single rotor helicopter is comparable to riding an unicycle, where as quadcopter pilot skills are comparable to riding bicycles. Offering the best of both worlds, Quadcopters are easy to learn and wind resistant at the same time. Every other quadcopter motor is alternatively a clockwise and a counter-clockwise rotor to cancel torque. This inherently stable quality is further assisted by 3-axis gyro technology in the form of a flight controller plus GPS based functions on more sophisticated systems.  While payload under a traditional helicopter structure is at best awkward, multicopters are well suited to carrying cameras and gimbals.

BASICS QUADCOPTER CONTROLS
A RC Quadcopter is piloted via a transmitter radio’s joysticks and switches. These instructions are then transmitted and received by a receiver on the quadcopter. The quadcopter flight controller serves as the central station where all incoming information is processed. An advanced attitude sensor or 3-axis gyro provides continuously updated flight status while the flight receiver relates instructions from the flight transmitter operated by the pilot. Mixing the pilot’s signals with output from its electronic gyros, the flight controller algorithm calculates and signals the ESCs which in turn determines the speed of individual motors. Even with proper instructions, it's still up to the power of the rotors and the stability of the structure to execute flight requirements.

A TORQUE FREE ARCHITECTURE
While the main frame (hub) houses all the electronics, four radiating arms (booms) provide stable mounting positions for 4 rotors. Each rotor consists of a propeller driven by a motor controlled by an ESC (electronic speed controller) which is usually located on a ventilated location near the main hub. Applying Newton’s third law of physics - for every action force there is an equal and opposite reaction - a quadcopter’s clockwise and counter clockwise rotors results in a torque free system. In contrast, a conventional helicopter’s single clockwise rotor forces its fuselage to rotate in a counter-clockwise direction which is then countered by a very complex and vulnerable tail rotor system. With 4 rotors doing the work of one, quadcopter rotors also don’t have to rotate as fast for less twitchy controls.

MOTORS AND MANEUVERS
Quadcopter motor#1 and motor#3 are counter-clockwise and motor#2 & motor#4 are clockwise. Increasing and decreasing rotor speeds on any side creates the pitch (tilting forward or backward) and roll (banking right or left) responsible for a quadcopter’s lateral directions. The synchronized speed of all motors provides throttle (climbing & descending) to control the quadcopter’s altitude. As oppose to using the tail rotor for the yaw (turning right or left), a quadcopter utilize the torque differential between the clockwise and counter clockwise propellers. For example, by speeding up the clockwise rotors and/or slowing down the counter-clockwise rotors, the quadcopter gather more torque towards the counter-clockwise direction thus turning the quadcopter's heading to the left.      

THE IMPORTANCE OF CENTER OF GRAVITY
Having a well-balanced CG (Center of Gravity) is crucial to any aircraft operations. In the case of quadcopters, CG is usually located in the midpoint between four rotors. Any payload, such as camera and gimbal not located at the quadcopter’s CG are usually compensated by moving the battery in the opposite direction. Without proper CG, one or more of the quadcopter rotors will constantly strain to maintain balance. Due to a lack of knowledge, experience and planning, CG is often the Achilles’ heel of small integrators & DIY quadcopters. A flight controller with associated gyros should be located at CG. To adjust and verify proper CG, find 2 opposing points next to the flight controller and lift the quadcopter with your left and right index fingers. The quadcopter should represent a well leveled seesaw. If the quadcopter is not properly balanced, the operator can adjust CG by moving either the payload or the battery until the seesaw levels.

AERODYNAMICS
A quadcopter's aerodynamics is quite different than that of an airplane. Unlike wings provinding lift on an airplane, extensive quadcopter surfaces represent a significant liability in wind resistance. This is especially critical in windy conditions and when a quadcopter is descending. More advanced
DJI Naza and Wookong flight controllers and SimonK electronic flight controller firmware offer algorithms that address both issues.

STRUTURAL INTEGRITY WITHOUT EXCESS WEIGHT
Inadequate infrastructure can negatively impact larger quadcopters than smaller systems. Since smaller quadcopter possesses neither high torque nor long arms, rigidity on smaller toy quadcopters doesn’t have the same relevance compared to larger structures. The lifting power of rotors provides a quadcopter’s buget as in the overall takeoff weight. If you exhaust this budget with a heavy structure, you will nothing leftover for payload. Therefore, larger quadcopter with more powerful rotors require the integration of stronger but lighter materials. Strong and rigid integration of carbon fiber or aluminum booms, brackets and propellers on a well-structured central hub are hallmarks of an uncompromising design. Cheaper quadcopters usually resort to mass-produced plastic injection arms and brackets that result in excessive flex and mass.

SIMPLICITY EASES MAINTENANCE & REPAIRS
If you haven’t notice already, there are no gears or long shafts on quadcopter designs. Fast spinning gears on long vulnerable shafts are a pain in the neck to align and maintain on helicopters. Ever try mounting pinion gears on helicopter motors? Never mind, that’s another nightmare you don’t have to deal with on a quadcopter. In fact I’m dumbfounded that commercial helicopters aren’t quadcopters.  One possible factor is the cost of four sets of  motors and controls (ESCs) versus one. On smaller cheaper quadcopters, a $5 set of motor and ESC multiplied by 4 is only $20. But on a much larger quadcopter, with a $200 set of motor and ESC the total cost for 4 motors and ESCs is now escalates to $800.

THREE BASIC CATEGORIES OF QUADCOPTERS
Beyond the obvious limitation of size in quadcopter functions, are the effects of different components on performance. With a wingspan (propeller tip to tip) of 6” to 12”, toy quadcopters are usually constructed from molded plastic parts and brush motors. A couple of popular models include the Walkera Ladybird and E-Flite Nano QX/MQX which are perfect for pure enjoyment and getting your feet wet.  Next comes the hobby quadcopters at 13” to 24”. These mid sized quadcopters can usually carry small cameras but struggle with gimbal (camera mount) options due to a lack of power, flight time and stability. Good videos are possible with upgraded hobby quadcopters in perfect operating conditions - in other words all stars have to be aligned for a decent video. For professional and industrial applications, there is no substitute for a full size quadcopter with an ideal mix of high quality components. Only with a wingspan approaching 3 feet or more, can a quadcopter generate enough power and lift to accommodate higher quality gimbals without compromising safety and video stability. Some of the quadcopter models are fully assembled, tested and ready to fly (Walkera Lady Bird/QR X350, E-Flite Nano QX/350 QX, Turbo Ace X830/Matrix, DJI Phantom, CX650-R) while others are just kits (Gaui 330X/S & 550X/S, AX650-K) which require assembly and testing. Further more many DIY systems will require additional receivers and transmitter radios (Gaui 330X/S, & 500X/S, AX650-R, CX650-R).

* Toys & Trainer Quadcopters: 6-12 inches wingspan (Walkera Lady Bird, E-Flite Nano QX/MQX,) These micro are well suited for both indoor & outdoor flight. And because they are lighter and more resistant to crashes, they are often used for training quadcopter pilots.

* Hobby Quadcopters: 12-24 inches wingspan (Walkera Hoten-X/QR X350/MX400, TBS Discovery, DJI Phantom/Vision, Gaui 330X/500, AR.Drone, Arducopter) Most of these quadcopters has the capacity to carry a small camera such as the GoPro Hero3. Due to limited payload, the addition of camera mounts or gimbals on these system will significantly compromise performance, flight time and video quality.

* Professional Quadcopters: 25-30 inches approximately (Turbo Ace Matrix/X830/X720, Draganflyer X4, Lotus T380/T580, AX650-K/R, CX650-R) With larger and more powerful rotors, professional quadcopters are especially prone to structual difficiencies (e.g. T380/T580 quadcopter). Look for a well braced infrastructure with stiff carbon fiber or aluminum booms (e.g. X830 quadcopter). Foldability for shipping and storage is an important asset for many professional applications. A comprehensively glide and lock solution is crucial in provinding both rigidity and security (e.g. Matrix quadcopter).

PILOT TRAINING FOR DUMMIES
Kick start pilot training with fun and motivation. Although simulator offers a controlled environment, it should only play a supplemental role in pilot training. The primary training tool should be an inexpensive palm sized quadcopter (e.g. Eflite Nano QX at $89.99) instead of a hobby quadcopter (e.g. Phantom at $479). Lighter palm sized quadcopters are extremely crash resistant so you will spend more time flying and less time fixing. Even if you eventually break a propeller, it only takes about a minute to switch out a $1 propller on a small quadcopter (E-Flite Nano QX). Charge up 3-4 batteries in advance and schedule 20-30 minute sessions 5 times a week. Initially fly in a tail-in (tail towards the pilot) orientation so that the transmitter's cyclic (directional) stick corresponds to the quadcopter's direction. Stay at least 2-3 feet above the ground so the wash (deflected air) from the ground does not interfere with the quadcopter's stability. With consistent practice, training sessions can then focus on intermediate orientations (e.g. tail-out & tail-to-left-or-right) and patterns (e.g. circles and figure 8). Depending on individual's hand-eye coordination, you should be ready to transition to conservative flights on larger quadcopter in a couple of weeks. Any prior experience with RC cars, airplanes or even video games will certainly speed up this process.

THE UPGRADE TRAP FOR HOBBY SIZED QUADCOPTERS
In general, camera and gimbal payloads exert to much stress on smaller quadcopters, the main cause of deteriorated video stability and shorter flight time. Rampant problems call for an ever increasing amount of remedies. From carbon propellers that exert to much force on stock motors to larger motors that exert to much force on weaker frames, solutions often lead to new problems. Misinformation and exaggerated upgrade claims from factories, vendors and overzealous “end user” reviews often leads to unrealistic expectations. The rule of thumb is don’t expect miracles if you combine several upgrades on hobby sized quadcopters. However, temptation often trumps sensibility. Typical Phantom quadcopter upgrades start with a set of stiff carbon propellers ($60), a good brushless gimbal for Hero 3 ($200 + installation) and swapping out the unreliable transmitter and receiver ($450 + installation). Oh let’s not forget to add the telemetry and video transmitter to the payload ($200). Then for extra measure, why not double the battery to get more flight time ($50). Now even as you cross those fingers, there is a sense that something might be off and you are right. As the quadcopter takes off there is an initial sign of relief, then comes the bad news. Any hobby quadcopters similar to the size of the Phantom will be overloaded at this point. The controls are sluggish. The flight time has only increase from 5 to 7 minutes. Ones you look at the resulting video, reality sets in. Perhaps the online video that you are desperately trying to replicate took 20 takes on a perfect windless day.

GO BIG OR GO HOME
In the world of quadcopter there is no substitute for size and power. Stock propellers take comes with quadcopter is a very good indicator of the quadcopter's capacity to carry payloads because you are not forcing small stock motors to drive larger after market propellers. If the plan is to stick with a small camera without an auto-stabilized gimbal, a minum of 8" propellers will suffice. Flight time will be approximately 6 to 7 minutes with the camera onboard. If you try to maxout the flight time like the ones on youtube videos, you risk damaging expensive batteries. When you use higher capacity battery on a small quadcopter, you are trading performance and video stabiilty for marginal flight time gains. If you go overboard with a huge battery, the flight time will actually decrease. For most videographers, an ideal setup is a compact camera mounted on an auto-stabilized gimbal (camera mount) with video transmitter for live video feed. Video stability and flight time with this larger payload require a big quadcopters with 12" propellers (e.g. X830 quadcopter) for about 9 to 15 minutes of flight time depending on the size and weight of battery you are willing to implement. Going bigger with 15" propellers (Matrix quadcopter) will yield 20 to 25 minutes of awesome stability.

A NOTE ON OPEN SOURCE ARDUINO
Open source Arduino flight controllers might be a tempting format for individuals who are interested in adding customized features for research. But generally speaking, the most desirable user-friendly features are already integrated on leading flight controllers. Even from the point of view of an experienced hobbyist, Arduino presents an extremely difficult challenge. Integration may take months and the outcome is often disappointing because a massive amount of tuning is required.

DRAWBACKS OF STANDARD TRANSMITTER & RECEIVERS
Consistent signal clarity at longer distances is vital to reliable quadcopter operations but stiff competition in transmitter brands is a breeding ground for overstated specifications. It’s one thing if you are dealing with a $50 toy that weighs a little more than a paper airplane. It’s a whole different matter if you don’t want to jeopardize $3,000 of equipment. Toy transmitter range is usually about 50 feet. If you go beyond this range you may never see the little quadcopter again because the controls are usually stuck in the throttle up position when pilot looses contact. Although hobby grade 2.4GHz transmitter such as the ones used on Walkera and DJI Phantom quadcopters are specced for 300-500 yards, the real distance is only about 200-300 feet. Without an established standard for testing, a manufacturer can easily claim a 3,000 feet range when the signals is only working 90% of the time. Even if a transmitter is functioning wtih at 95% reliability per minute in a 500 feet distance, you will likely loose signals in every other 10 minute flights. For the most part, a failsafe Return-to-Home function is able to save and recover your quadcopter from signal lost. However, prerequisites include having proper GPS calibration for specific locations, establishing GPS based home position prior to takeoff, maintaining all satellite connections and hoping no trees/buildings are in the way. With these real world concerns, it's best to integrate a reputable transmitter and receiver with reliable signals than to be overly dependent on GPS based Return-to-Home functions.

RELIABLE LONG DISTANCE TRANSMITTER & RECEIVERS
To address safety and to safeguard your long term investment, a reliable transmitter and receiver set up is an indispensable element of any professional aerial video platform. To service long range operations, a new generation of advanced transmitters such as the Spektrum DX8 and Futaba 14SG employ a combination of cutting-edge technology in the 2.4GHz bandwidth. Frequency hopping technology enables the transmitter to hop amongst bandwidths with the least amount of traffic. Advance algorithms on multiple receivers or antennas are implemented at different locations for signal path diversity. And, as a last line of defense, these faster transmitters can recover from signal loss within a fraction of a second (as oppose to 3-4 seconds on standard 2.4GHz transmitters), way before the failsafe Return-to-Home function kicks in.

VIDEO STABILITY
Because a quadcopter is a moving platform that can tilt, roll or pan, it’s often difficult to consistently stabilize a subject in your frame. Fortunately, many of the more advanced camera mounts can automatically compensate for a quadcopter’s movements. Continuous signals from onboard attitude sensor or 3-axis gyro in combination with your transmitter input effectively instruct the servo(s) on the camera mount where to point. This compensation significantly stabilizes the image. As with each apparatus, there are limitations as to how fast the servos can move. So the stability of the quadcopter is paramount in provide quality footage that you can later utilize. Even with the best camera mount, you will still see some residual motion which can be filtered out by utilizing a video stabilizing software such as Mercalli which is a very practical software tool for the average videographer or photographer.

On the other hand even the quickest multi-axis camera mounts and the smartest stabilizing software can not neutralize excessive video vibrations. These critical elements must be addressed at several different levels. The root of most vibration problems starts from the quadcopter’s rotors with well balance motors and propellers producing less vibrations. Some motors are dynamically balanced at the factory such as brushless motors use on the Turbo Ace X830 & Matrix. Similar to balancing a tire, each motor is spun at high speed and small amount of material is added to a few selected edges of the motor drum until the rotation is completely smooth. As for propellers, a similar procedure can be used to balance them with an inexpensive blade-balancing tool. Propellers are usually quality controlled but not factory balanced so end users need to complete this process to reduce vibrations for each individual propeller. Finally, even with properly balanced motors and propellers, there will still be some residual vibrations. The last line of defense is to isolate the vibration from the camera mount. For heavier cameras & gimbals, look for a more substantial vibration dampening system. Inadequately matched dampening features sometimes weaken a gimbal’s foundation, and the extra layer of components becomes counterproductive.

CAMERA MOUNTS & GIMBALS
How can such a simple device play a critical role? Well, having a super stable quadcopter without a good camera mount is analogous to a good camera with lousy lenses. Premium video can be easily compromised by a wobbly camera mount with sluggish controls, often a consequence of substandard material, hardware and design. To select an appropriate camera mount, first determine how many axis needs to be auto-compensated by gyros and/or accessed on your transmitter. For single-axis camera mount (e.g. Gaui G-210705 & HM-UFO-MX400-Z-32), look for a rigid structure to carry the camera. Since single-axis gimbals are sometimes used on smaller quadcopters, minimizing weight is often a contributing factor in reducing structure. As for 2 and 3 axis camera mounts, there are two basic designs. The lighter simpler pivot design on a quadcopter can be very effective in turning out quality video without too much fuss. Strategically placed servos drive the structure to pivots on 2 or 3 axis. Pay special attention to the both the material and the joints used to establish a structure that can retain its shape while holding and moving the weight of a small to medium size camera. Flush bearing is an integral part of the pivot design (ALA3CM01) and so are high quality metal gear servos of the appropriate size, speed and torque. Pivot gimbals improvised with hinges (Helibest) results in uneven movement and will eventually fail prematurely. For heavier cameras, you might want to consider the track mount gimbals using a combination of tracks and pivots. The track mount gimbals can be quite heavy which can affect both payload and performance. You will need at least a very powerful hexacopter or octocopter.

The size of and dimension of your camera can greatly affect you choice for gimbals. First make sure the camera will fit in the gimbals with the proper alignment of mounting holes and hardware. As with helicopter, quadcopter and multi-rotors, center of gravity on a camera mount is also key consideration. When a servo attempts to move both the gimbals structure and the camera, the combined center of gravity will need to be close to the pivot point. If the center of gravity is too far off, the servo will strain to lift and offset the difference. Forcing servos to lift unnecessary weight will cause undesirable jerky movements and reduce the life span of both the servo gears and motor. A versatile camera mounts for your quadcopter can usually be adjusted to accommodate a variety of camera configurations. Before attaching your gimbal to the base of a quadcopter, first test the center of gravity with the camera that you are using. Whether if you are using a one-axis camera mount vs a 2-3 axis, the procedure is the same. By holding the gimbal near each pivot point you can see if the camera is tipping towards a certain direction. You should move the camera in the opposite direction on the mounting plate until you achieve the best balance.

STRUCTURAL STRENGTH, PAYLOAD AND STABILITY
At this juncture, you are well aware of the importance of payload. So, please be warned that differentiating between flying weight and total weight with and without battery is very different. Payload, battery sized, flight time, stability and performance are all inter-related. A chart may be very misleading because you won’t have the stability and performance factor that is critical to a secured flight with expensive equipment on board. Always go on the safe side when specking your equipment for payload. If a quadcopter is able to pull 3LBs, that may mean that the quadcopter will barely get off the ground with 3LBs. What if you add a larger heavier battery or if the battery gets weaker after 2 minutes?

Another often overlooked factor, structural strength, will significantly affect the ability to carry heavier camera equipment such as DSLR cameras. Most quadcopters has the payload capacity to carry 2 lbs but lack to structural integrity to sustain the weight without flexing. Flexing which causes a dangling and bouncing effect is detrimental to both video stability and flight stability. Especially when dealing with a larger wingspans on a hexacopter or an octocopter you need to make sure the overall structure is sufficient to suspend the payload in addition to the carrying capacity of the multi-rotor helicotper.  Look for a well braced super structure which will sustain the addition weight without sagging the center hub where the weight will be attached. Hexacopters and octocopers which are integrated mainly from carbon tubes are generally results in a weak central hub and arms that are too and thin for the wingspan. Although DSLR cameras are getting smaller and lighter, you are still encouraged to acquire the most powerful quadcopter, hexacopter or octocopter you can afford with special consideration for adequate payload and structure to address proper performance.

Conceptualized by master FPV pilots, Matrix is a quadcopter designed for rather than adapted to carrying cameras. To satisfy an almost insurmountable list of high expectations, Turbo Ace engineers set out on a journey of innovation and discovery. Applying more than 85 years of combined helicopter and multi-rotor expertise between our master pilot group, engineers and designers, the Matrix represents an ultimate breakthrough in quadcopter engineering and optimization. To search for the ultimate mix of performance and durability, Turbo Ace developers matched up countless motors, ESCs and propellers combinations followed by series of unrelenting updates and test flights. From planning and implementing the best components on a foldable structure, setting and meeting new milestones in flight time and payload, to executing crucial requirements for flight and camera stabilization, the Turbo Ace Matrix is truly a quadcopter beyond its time.   

UNPRECEDENTED PAYLOAD & FLIGHT TIME
Matrix's big breakthrough is an amazing 25-minute flight time carrying the #1 selling GoPro Hero3 stabilized on the ultra fast 2-axis brushless Gyrox3 gimbal. Cutting out the gimbal but keeping the Hero3 on a vibration isolation plate will extend Matrix flight time beyond the amazing 30-minute threshold. Despite many unrealistic claims, the closest competition offers less than half the flight time. At about 3 times the size of a mid-sized quadcopter, heavier payloads exert disproportionately less impact on Matrix flight time than smaller quadcopter flight time. Without exception, even the top selling mid-sized quadcopters with 8" to 10" propellers will max out at 5-6 minutes with Hero3 and gimbal onboard.  It's not uncommon for both vendors and end users to exaggerate or manipulate payload and flight time by gutting critical components inside quadcopters and cameras or by using lighter batteries with limited rechargeable cycles.
   
IDEAL UNOBSTRUCTED AUTO-STABILIZED CAMERA/GIMBAL LOCATION
Tired of propellers and landing skids framing your video? The Matrix's nose offers an ideal location with unobstructed view - no propellers even in wide angle videos, no skid landing when pointed down and no more annoying propellers shadows on the lenses. Although these are nagging issues, there are even more crucial factors in achieving stability. Because traditionally mounted cameras are about 8 inches below the main hub, a quadcopter’s roll causes the camera to swing like a pendulum. Although a good gimbal is able to compensate for the roll axis movement, it's unable to address the horizontal movement resulting in videos that shift from side to side as if a skater is holding the camera. By moving the gimbal and camera up to the level of the propellers, the Matrix design has basically eliminated the pendulum effect. Last but not least, gimbals are only as stable as the foundation they are mounted on. Bypassing the weight and slack of unstable under-mounted gimbal platforms, Matrix's gimbal is mounted directly on the main frame to prevent oscillation from surfacing.

FOLDS AND FITS NEATLY INTO A CARRY-ON SIZED ALUMINUM CASE
No more awkward quadcopter with protruding arms and propellers to lug around. Unlike typical folding mechanisms, the Matrix's arms and landing skids are designed to lock into folded or operating positions so you don't have to sacrifice structural integrity for portability. Implementations of slotted tracks enable fast and secured transitions without the risk losing any hardware. For a day out in the park or a hiking trip, you can retract the arms and skids to reduce the footprint. And for traveling, foldable antenna enable the Matrix and the transmitter to slip comfortably into a professional aluminum case without dismounting the propellers and gimbal. Upon arrival at the flight location the operator can adjust the landing skid height to accommodate rougher terrain. An optional aluminum case even includes cutouts for transmitter, batteries, spare parts & tools. Who knows, you might have a trip planned for Europe and the very versatile Matrix can make a great companion as a carry-on.

STRONG AND VERSATILE STRUCTURE FOR COMPREHENSIVE INTEGRATION
In housing and supporting an extensive list of stock and upgrade components on a super scaled quadcopter, Matrix's triple decked carbon fiber structure is extremely strong and versatile. Four foldable arms which double as supporting beams are securely sandwiched between the lower decks along with multiple ventilated ESC positions. The middle deck houses and protects all critical electronic components such as the flight controller, the GPS, LED and other optional systems. Versatile Battery and ESC mounting positions allows the operator to shift CG (center of gravity) upward, downward, forward and backward to accommodate a wide variety of payloads and flight characteristics. Mount the battery below the lower deck for more stable flights or move the battery to the upper deck to increase maneuverability. And to counter balance different camera payloads, you can shift the battery, ESCs and arms into optimal positions for proper CG.

DYNAMICALLY BALANCED MOTORS & OVER-SPECCED ESCS
For exceptionally smooth flights, Matrix super muscular 42mm brushless motors are dynamical balanced. Since brushless motors are hand wound, the mass center is usually not in alignment with the mechanical center. Using advanced electronic balancing instruments, our factory spins up each motor then make proper adjustment to bring the mass center into alignment. Then to control and power the motors, Matrix 40A ESCs feature advanced multi-rotor algorithms which offers better performance and reliability than generic helicopter algorithms. Over specced to sustain unrestrained amperage in higher torque for acceleration, extreme maneuvers and bigger payloads, Matrix is engineered to operating below capacity, so mechanical and electronic components stay relatively cooler even with consecutive flights.

STIFFER & THICKER DOUBLE-POINT MOUNTED 15" CARBON PROPELLERS
No propellers are created equal. 15" Matrix robust carbon fiber propellers are sculpted with extra thick mid-section to resists flex then tapers to efficient blades to cut through the air with minimal resistance. Traditional circular mounts are accidents waiting to happen because the force of rotating propellers will eventually unscrew the crown nuts during flight. Integrated double point mounts on Matrix motors and propellers eliminate this possibility and at the same time improve tracking precision because the propellers are forced to sit flat against the top of the motors. Another benefit of a flat mount is that there are no vulnerable protruding motor shafts. Slight deviations in traditional circular mounting holes or protruding motor shafts are extremely difficult to detect which magnify pitch and tracking variances, a major cause of vibrations and unstable flights. Since end-users are often required to purchase and mount propellers, Matrix's new hassle free mounting configuration is implemented to prevent vibration issues from surfacing.

SELECTABLE MANUAL, ATTITUDE & GPS FLIGHT MODES
A 3-positioned switch is setup on Matrix' transmitter for pilot to select between 3 different flight modes. (1) With Manual Flight Mode, the absence of Gyro assisted flight makes it very difficult for the Pilot to stabilize and maneuver the quadcopter. (2) For 3-axis gyro auto-stabilized flight, the Attitude Flight Mode will automatically keep the Matrix in a leveled and sustainable flight thus enabling the pilot to focus on maneuvering the quadcopter. (3) Finally, the GPS Flight Mode is the most often used mode because it combines the benefit of 3-axis gyro auto-stabilized flight with 4 advanced GPS based functions described below.

GPS-LOCK & RETURN-TO-HOME
Under GPS Flight Mode, (1) one of the most utilized GPS based functions is the GPS-Lock function. Simply release the cyclic stick and allow it to spring to the middle of the control and the Matrix will be locked into a fixed GPS location (longitude-lock and latitude-lock) with a tolerance of 3 to 5 feet radius. Another similar function from the Matrix flight controller, the Barometric-Lock can be activated by moving the throttle stick to the middle of the control and the Matrix will be locked into a fixed elevation (altitude-lock). A hands-free hover modes is established when the pilot activates both the GPS-Lock and the Barometric-Lock simultaneously and the flight controller takes over. Either lock may also be used independently to hover in a fixed GPS coordinate with pilot controlled elevation or the longitude/latitude. By relinquishing controls to these auto-hover modes, the pilot can better focus on monitoring the video and controlling the camera. (2) Another popular GPS function is the Return-to-Home sequence, a preprogrammed failsafe function which is automatically triggered by lose of remote control signals. Upon activation, the quadcopter will hover in place for a couple of seconds before elevating to a preprogrammed height and return to the home position for an automated landing sequence.

GPS BASED COURSE-LOCK & HOME-LOCK
Under GPS Flight Mode, there is dedicated 3-positioned carefree mode switch set up to access (3) Course-Lock, a compass based carefree mode that remembers the initial take-off direction of the flight which is used to consistently orient the quadcopter. Under Course-Lock, the transmitter radio must remain in the initial take-off direction until it's reset or until the quadcopter lands. For example, with the transmitter pointed in the eastward direction, a quadcopter takes off in eastward heading orientation then turns towards a northward heading. Without Course-Lock, a transmitter cyclic (directional) stick moved up towards the east will cause the quadcopter to head northward. Under Course-Lock, a cyclic stick moved up towards the east will cause the quadcopter to head eastward which is consistent with the initial take-off direction. In fact, by keeping the transmitter pointed in the initial eastward take-off direction, the cyclic stick direction will always correspond to the direction of the quadcopter no matter how the heading has changed. At any time the pilot may reset the initial direction by flipping the Carefree Mode Switch in and out of Course-Lock. (4) Lastly, there is another similar carefree mode with a twist. Home-Lock, a home coordinate based carefree mode is very similar to Course-Lock. The difference is that Home-Lock uses the home location as the consistent tail-in orientation for the entire flight. While this allows the pilot to constantly turn and follow the quadcopter, the pilot should not move away from the home location. And because GPS has a tolerance of 3-5 feet, Home-Lock is less precise than Course-Lock. However, as the quadcopter gains more distance from the home position the precision improves dramatically. This is why Home-Lock will not and cannot be activated within a 30-feet circle from the home position. To use Home-Lock, the pilot usually maintains a tail-in orientation until the quadcopter is well beyond the 30-feet circle before assuming that Home-Lock has activated. At this point the pilot can constantly turn and point the transmitter at the quadcopter and the cyclic stick will always correspond directly to the quadcopter's direction. To bring the quadcopter back, the pilot simply pulls the cyclic towards himself - basically a manual controlled return-to-home function. Special caution is required when the quadcopter approaches the 30-feet circle because Home-Lock will automatically switch to Course-Lock. If the quadcopter enters the 30-feet circle from the initial take-off direction so that Home-Lock is equal to Course-Lock the pilot can assume that the quadcopter is under Course-Lock until the quadcopter lands. In summary, an experienced pilot uses the "Normal" flight mode because no help is required from GPS. Both Course-Lock & Home-Lock carefree flight modes enable the operator to pilot the quadcopter without keeping track of the quadcopter's tail position. This is especially useful if a less experienced pilot is rotating the quadcopter to pan the video. There is much less confusion for beginner pilots to stick with either "Normal" mode or use GPS assisted Course-Lock. Home-Lock is usually reserved for longer distances within-the-line-of-sight flight because it's a bit confusing to operate when it approaches the home position.

ULTRA DURABLE & MAINTENANCE FRIENDLY
All Matrix material and components are selected and built for reliability and durability. Premium carbon fiber is utilized in the main frame for its rigidity and light weight properties. Wear resistant CNC aluminum are utilized in screw-mounted joints, brackets and posts. Tough Japanese bearings are implemented to guard against higher temperatures. Then for continued maintenance, Matrix is based on a modularized design with strategically placed high tensile strength connectors so it's extremely easy and cost effective to maintain and operate. With minimal disassembly, components can be independently removed and replaced to diagnose and repair problems. As with all Turbo Ace production models, well stocked Matrix parts and upgrades are manufactured in larger volumes and savings are passed on to end-users. Operators are encouraged to keep some backup parts such as spare propellers, screws and batteries for replacement. Complimentary Turbo Ace videos are available online to assist operators in maintaining and upgrading the Matrix.

EXPANDABILITY WITH OPEN ARCHITECTURE & UPDATABLE ONLINE FIRMWARE
Catering to research professionals and avid hobbyists, the Matrix welcomes a full spectrum of specialized modifications.

CAMERAS
Aerial cameras mounted under quadcopter serve two main purposes. (1) First and foremost, cameras are used for the purpose of recording videos or taking still photographs. Preferably, a DSLR camera is mounted on an auto-stabilized gyro based gimbal (camera mount) to stabilize the camera's horizon. (2) For more experienced pilots, a camera can be used for the purpose of piloting the quadcopter from the point of view of the camera AKA FPV (first-person-view) piloting. If the camera is either mounted directly on the quadcopter without stabilization so the pilot can experience the tilt (pitch) & roll of the quadcopter. If the camera is auto-stabilized, OSD (on-screen-display) may be required to overlay artificial horizon and flight status on live feed video.

VIBRATION ISOLATION MOUNT & AUTO-STABILIZED CAMERA MOUNTS ON MATRIX
Employing vibration isolation mount for camera can significantly dampen high frequency vibrations to prevent rolling shutter & jello effects on videos. And for more professional applications, we can optionally add gyro based camera mounts to automatically stabilize cameras to accommodate quadcopter's tilt & roll movements to maintain a leveled video horizon. To control the camera's aim, a dial switch on the transmitter radio enables the pilot to tilt the camera up or down. With the freedom to maneuver and turn the quadcopter from different perspectives, heights and angles, one can achieve an endless variety of high quality shots and videos.

FPV LIVE FEED VIDEO
Live feed video enables the pilot or cameraman to see real time videos from the camera's point of view is synonymous to FPV (first-person-view). In contrast to slower and shorter distanced WiFi video streaming on cameras, aerial FPV requires much longer distance transmission without visible delay. A video transmitter is usually attached to a camera's video-out port to transmit the video signals. A matching video receiver, located next to the pilot or cameraman, receives the video signals. The receiver is connected to a monitor mounted on the transmitter displays the video live so the operator is able to pilot and watch the live feed video at the same time. There are 2 main purposes for aerial FPV. (1) To enable pilot/cameraman to see and frame videos or still shots by adjusting the gimbal and/or the quadcopters location and orientation. (2) To enable pilot to see and fly from the point of view of the camera - as from the cockpit. If a camera is hard mounted without auto-stabilization, the video will reflect the tilt (pitch) and roll of the quadcopter. If a camera is auto-stabilized on a gimbal, an OSD (on-screen-display) may be implemented to overlay artificial horizon and flight data on the auto-stabilized footage which do not reflect the tilt and roll of hexacopter.

STANDARD & LONG DISTANCE TRANSMITTERS FOR MATRIX
Due to safety and equipment concerns, transmitter reliability is crucial in professional quadcopter operations. Without an established standard of verification, it's common place for transmitter brands to overstate operating distance by discounting the importance of reliability. A typical transmitter spec for 2,000 feet range may only be reliable 80% of the time and you can easily lost your equipment in several flights at 300 feet. Only extensive field testing over several months - not biased reviews based on several test flights - are true indicators of consistently reliable operating range.

TRANSMITTER & RECEIVER OPERATING REQUIREMENTS
Standard remote control transmitters and receivers utilized with the Matrix quadcopter operate under FCC Part 15 (S29DEVO-10, BRWDAMTX11, AZPT14SG-24G, S29TX5803) in either legal 2.4GHz and/or 5.8GHz frequencies. In general, advanced quadcopters require a minimum of 7 channels under the 2.4GHz frequency range: 4 channels for piloting controls, 2 channels for the GPS and 1 channel for controlling the tilt-axis of the gimbal. Extended distance transmitters usually employ several methods to promote signal strength and reliability. (1) Frequency-hopping spread spectrum (FHSS) is a method of transmitting radio signals by rapidly switching between several frequencies to seek the least amount of traffic. (2) Dual or triple paths diversity enable signals to reach two receivers or antennas mounted in different locations on the quadcopter enables the transmission to utilize the strongest signal path. Bi-directional receivers can also communicate signal strength between the receiver and the transmitter to locate the best frequencies in real time (3) In case of signal disruptions, ultra fast signal recovery algorithm enables the transmitter and receiver to quickly rebind for continued operations. Products using permitted frequencies without certification will require an amateur radio (ham) license. It is the operator's responsibilities to ensure the use of such products meet their individual countries' federal and local government's rules or regulations for RF devices. If you are unsure of your government's requirement or unable to comply with them, please do not purchase this product. Please do not alter the purchased product in violation of said rules and regulations because Wow Hobbies cannot be held liable for operator's misuse or modification of a legal product.

INTEGRATION, SET UP, FLIGHT TEST & SHIPPING
There is a myriad of Matrix options to satisfying specific applications. After installation, setup and inspection, our technicians will complete final adjustments plus a series of test flights. If your orders is placed for pick-up, we will redo a live flight-test when you arrive at our showroom. If your order is to be shipped, a test flight video for your specific Matrix order will be recorded, saved and shipped with the instructions in a flash drive. Our Matrix packages are designed to retain all assembled components as a fully integrated system during shipping. To prevent damage, the Matrix quadcopter is suspended in the middle of a large corrugated shipping box.

MATRIX STARTING TIPS
* Make sure you read the entire Matrix Instruction Manual on flash drive before you operate the Matrix.
* Follow the instruction manual for a tied down flight test. This is the safest way to make sure the Matrix quadcopter has not been damaged in shipping.
* Foldable Matrix aluminum arms operate on guiding carbon tracks with locks on each end. To release the arm from the folded or operating ends of the track, you need to unscrew the arm bolt several turns for a height of 1/8” before the lock will release. If the bolt is not unscrew to a sufficient height you may risk damage to the carbon track.  
* Prior to each takeoff, make sure the GPS antenna/compass is erected from the folded position.
* When mounting a propeller, make sure the propeller clamp sits completely flat against the top of the propeller.

MAINTAINING MATRIX'S LIPO BATTERIES
* Please read charger instructions to set up the charger to charge Matrix LiPo batteries before you start.
* Matrix batteries are made up of 6 cells and each cell must be maintained between 3.7V to 4.2V. The total voltage for Matrix batteries should be maintained between 22.2V (3.7Vx6) and 25.2V (4.2Vx6). It’s very important for you to keep each cell above 3.7V. A cell is at risk of being damaged at 3.6V. And at 3.5V you are pretty much guaranteed damage. If any one or more cell is damaged, the 6-cell battery will not function properly and should not be used. Once you have set up the charger for the Matrix battery, the charger will automatically stop when the battery is fully charged.
* Each Matrix battery includes a yellow charging/discharging plug and a white balancing plug. Both plugs are used for charging the battery. The yellow plug with thicker gauge wires enables a faster charge rate while the white plug with 1 small red wire and 6 small black wires enables the charger to balance charge 6 individual cells. When all 6-cells reaches 4.2V each for a total of 25.2V, the charger will automatically stop. You should always monitor the charging cycle which takes about 1 to 1.5 hours for each battery. Battery should be stored in a cool location but not the freezer.
* A quick battery meter is the easiest way to monitor voltage on any LiPo battery. There are seven pins on the battery meter and one of the pins is marked with a “-“ symbol. Line up the black wire on the edge of the Matrix battery’s white plug with this “-“ pin then insert. You will see a total of 7 sequential numbers on the meter. The first number is the total charge of the battery’s 6 cells which should fall be between is 22.2V (3.7Vx6) to 25.2V (4.2Vx6) follow by six more numbers representing the individual charge of each of the 6 cells with 3.7V to 4.2V each.
* To prevent batteries from slipping out of battery straps, we highly recommend that you apply a 2” strip self-adhesive felt velcro on the batteries’ slippery surface. Due to possible fire hazard, a LiPo battery that is punctured or damaged, from a fall or otherwise, must be properly disposed immediately.

BEFORE & AFTER EACH FLIGHT
* Before each flight always turn on the transmitter first then plug in the Matrix battery. Then, you need to allow proper time for the flight controller & GPS to complete initialization (study the User Manual’s LED Description Section).
* After each flight always unplug the Matrix battery first then turn off the transmitter. If you forget, the quadcopter and/or transmitter will continue to drain power from the batteries. Once a LiPo battery falls below 3.7V per cell at no load, it will loose the ability to fully charge back up again. This rule also applies to all LiPo batteries used to power other accessories.

DOS
* Do initialize the Matrix & takeoff from a large leveled surface.
* Do implement a pre-flight checklist & use it consistently before takeoff.
* Do unplug the Matrix Battery when maintaining or upgrading the quadcopter.
* Do dismount propellers if battery is plugged in for updating flight controller.
* Do observe privacy concerns. Stay away from windows and backyards.
* Do recalibrate GPS if the Matrix has passed through airport X-ray screening.

DON'TS
* Don’t operate near airports or other sensitive government institutions.
* Don’t operate near people or pets & do not allow people to approach an operating quadcopter.
* Don’t operate in tight spaces or near vulnerable property.
* Don’t use magnets (e.g. magnetized screwdrivers & tools) in close proximity to the GPS antenna/compass.
* Don’t be tempted to catch a quadcopter. The torque of the propellers might surprise you.

Based on the feedback on the original Turbo Ace X720 quadcopter and the Xaircraft X650 quadcopter drones, Turbo Ace has taken a quantum leap with the release of the new X830-S quadcopter.
 
For more information on the X830-S visit the forum
http://www.rcgroups.com/forums/showthread.php?t=1554005&page=4
 
FEATURES VIDEO QUALITY:
For improved video stability, the X830 quadcopter features precision dynamically balanced motors that are rarely offered in multi-rotors. Balanced motors substantially reduce vibration, a common cause of poor video quality. Due to high rotor speed, exceptional vibration dampening X830 super structure offer an extra line of defense against harmonic vibrations. The X830 is designed to optimize video quality.
 
Example of video distortion: notice the word "COUNTRY". Go to http://www.wowhobbies.com/250seinstruction-2.aspx
The X-830-S videos are sharp with no wave lines and they also have no jello effect caused by high frequency vibration generated from unbalanced motors.

FLIGHT STABILITY & RELIABILITY
Turbo Ace has configured the X830 for optimized wind resistance and stabilization. The X830 dynamically balanced motors have been re-engineered to take multiple mild crashes. Instead of round or screw mount propellers, X830 quadcopter propellers are rectangular-oval key mounted on the neck of the motor bell which eliminates propeller slippage and significantly reduces the probability of accidental propeller dislodge. And by enveloping the a thicker motor shaft, the X830 motor are more resilient to minor crashes. Exposed motor shafts in all older designs are especially prone to damage and slightly bent motor shafts are hard to detect.
 
MAINTENANCE
The X830 quadcopter is extremely easy to maintain and cost less to operate. Entry quadcopter buyers are often surprised by the high cost of maintaining a multi-rotor helicopter. Each failure or crash can cost hundreds of dollars. The X830 is based on a maintenance friendly design. Independent modularized components can be easily removed and replaced. Connectors are strategically placed to ease maintenance and repairs. Custom CNC aluminum connections offers better alignment while reducing the amount of parts used. And due to larger volume, X830 quadcopter parts are more readily available at lower cost. For example: Instead of having to replace a 4-in-1 ESC that cost over $150, the X830 ESCs, at a small fraction of the cost, is easier to keep a spare on hand. High tensile strength spring loaded connectors that stand up to repetitive insertions is a lifesaver when it comes to trouble shooting and change motors or ESCs. In most cases you are no longer required to disassemble and pull wires through the narrow boom.
 
COOLER ESC OPERATIONS
The X830 quadcopter is highly reliable, it uses four 35A ESC with multirotor SimonK & cooling algorithm that can carry heavy payload with super low motor/ESC temperature. Unique placements of the ESC on the X830 are under the central hub of the quad where they are protected and well ventilated. The central location greatly reduces the chance of ESC damage in a crash or hard landing. The X830 quadcopter also does not use an internal cooling fan, the electronics are cooled naturally by the rotating flight propellers. The improved cover design features multiple vent holes keeping the flight controller running cool at all times.
 
POWER & PAYLOAD
Turbo Ace motors are build with high efficiency stators and they are over 20% more powerful than its Xaircrasft quadcopter contemporaries. Please take into consideration your flight time, performance, pilot ability and safety when loading up your X830. The X830 quadcopter can reasonably carry up to about 2 LBs. However, for better flight time and performance we recommend that you keep the payload under 1.2 LB. When tied to a reverse scale, the X830 quadcopter has an amazing lifting capacity of 5 LBs, one of the strongest quadcopter on the market today. A quadcopter lifting or payload capacity and be misleading. Putting 5 LBs on a quadcopter with a capacity to lift 5 LBs will basically neutralize its ability to fly. Putting 3 LBs on the same helicopter will cause significant instability making it very difficult to control the quad. Under no circumstance should any quadcopters be operating close to maximum pulling capacity. There are numerous factors to consider when calculating payload - for example flight time, battery size/output, temperature, altitude, wind velocity, stability, safety and the ability of the operator to pilot the quadcopter in adverse conditions. The best answer is to start with more conservative payloads and work you way up. Always be aware your surroundings and make sure you have ample of open space below your quadcopter. If you are still in the training stage, it might be advisable to operate only in calm conditions.
 
LOW RADIO NOISE: The X830 extension arms are made of heavier duty 12mm aluminum instead of the 10mm carbon rods. Unlike carbon arms in the X720 quadcopter, the aluminum arms are stiffer reducing harmonic vibrations, will not have fiber splits and carry low radio frequency interference. This translates to longer flight range, and low radio noise for better video image.

STRUCTURE and WEIGHT: The X830-S is designed with power efficiency in mind. This means that every gram is accounted for during the build. The motor mount, central hub went through tension, compression, bending, torsion and shear engineering to obtain striation integrity and weight savings. The propellers are keyed instead of screw mounted which greatly improve reliability.

SIMULTANEOUSLY CHARGE SEVERAL BATTERIES
Although a B601 is an excellent wall charger, it can only charge one battery at a time. With charging time ranging from 1 to 1.5 hours, it takes almost half a day to charge several large batteries. If you have a need to speed up the charging process, then the SKRC 320W charger is an excellent choice to charge 4 batteries simultaneously.
http://www.wowhobbies.com/320wchargerwith30apowersupplyandxhbalanceadapterplug4batteriesallinone.aspx
 
ALA2CM01 Camera Mount (2-Axis): One of the best choices to stabilize a small camera of up to 107mm width, the gimbal is driven by 2 servo to automatically stabilize videos.

ALS3CM02 Camera Mount (2-Axis): By far the most flexible choice, this Wow customized Alware camera mount can accommodate cameras up to 122mm. Wow has evaluated at least half a dozen promising candidates and this is best combination of a lighter setup with very effective roll-axis & tilt-axis auto-stabilization for smaller cameras
 
GYROX3 Brushless Camera Mount (2-Axis): The advent of brushless camera mounts has prevail over traditional servo based systems. Super fast auto-stabilized roll-axis and tilt-axis with pilot controlled tilt-axis offer solidly stable horizons without unintended movements. Expanded tilt-axis angle enables the camera to point straight down but optimized stabilization & mounting is designed to fix the GoPro Hero3 exclusively.

WALKERA MX400 QUADCOPTER
As with many new Walkera quadcopter models, make sure you are purchasing the most recent version of the MX400 quadcopter. Some of the colorful (blue) and heavier features (white plastic legs) on the original MX400 Version 1 had significantly reduced acceleration and payload capacity. Several improvements were implemented on the MX400 Version 2 that also included additional packaging and quality assurance. Featuring premium brushless motors on a well-constructed medium size frame, this ready to fly MX400 quadcopter offers the best value in the hobby. Quadcopter of similar size and quality such as the DIY Gaui 330X-S and 500X kits which can easily cost twice as much by the time you add the receiver and the transmitter. Since the MX400 is fully assembled, tested and comes in a handsome aluminum case, Walkera has taken the guess work out of researching in forums, shopping for components and integrating the complete quadcopter system on your own. Oh, by the way it also comes with an extensive set of impressive LED lights. There are two camera/camera mount options available. The first is a simple small custom fitted camera from Walkera and it's mounted directly on a slot under the MX400 quadcopter. The second option is to use the MX400 single-axis camera mount. Both camera/camera mount options are inexpensive. So if you are serious about taking HD video, you might have to adapt a higher quality camera mount to the bottom of the MX400. Another really useful option that you might consider is upgrading your MX400 with telemetry. If you had decided to purchased your MX400 quadcopter with a DEVO 8S/10/12S, then you are already halfway there. You can either have the vendor install the telemetry option at the time of the MX400 purchase or you can get the inexpensive Walkera telemetry module and hook it up to the on board MX400 battery yourself. With telemetry installed, you will be able to see the batteries' voltage on your transmitter as you are flying. Having this information will enable you to safely land the MX400 quadcopter without quessing how much power is left in the flight battery.

End your constant stress and worry about low battery and protect your RC heli/airplane investment. This transmitter can receive the telemetry voltage data on board the quadcopter wirelessly and the vibration alarm can be set to trigger at the voltage you defined. There is no way to miss a low voltage warning and you will never crash because you lost track of the battery power. The vibration alarm will remain on when the total voltage falls below what you set. You no longer need a battery meter and you no longer need to check your battery before each quadcopter flight, the voltage can also be clearly displayed on the transmitter LCD.

WALKERA DEVO 10 TRANSMITTER
Utilizing Walkera's cutting edge 2.4GHz technology, the Devo 10 transmitter is specifically updated to accommodate additional requirements in controlling multi-rotor helicopters such as quadcopters, hexacopters, octocopters and associated camera mounts. With faster response time and smoother stick movement, this state-of-the art transmitter offers significant improvements over traditional 2.4GHz transmitters. Because an increasing number of multi-rotor applications are used in professional settings, Wow's DEVO 10 transmitters are upgraded with a premium anodized “gun metal” finish. Stock DEVO 10 transmitters are either cheaper flat black versions or the silver versions which cause excessive glare under the sun. Many of DEVO 10's advance features such as a 7-point curve adjustments and additional dial switches for smoother camera mount controls are only seen on premium transmitters. Since quadcopter, hexacopter and octocopter pilots are usually handing multiple tasks, this specialized transmitter will in many ways play the important role of a co-pilot.

DEVO 10 TELEMETRY (Requires the installation of a Walkera telemetry module on the X88-J)
Protect your RC helicopter/airplane investment and put an end to constant worrying about running low on battery. This transmitter is set up to wirelessly receive updated telemetry data from the aircraft. To enable this function, you will need a Walkera telemetry module installed on the X88-J to acquire and transmit updated telemetry voltage reading before and during flight. Once this feature is on the X88-J, the voltage will be clearly displayed on the DEVO 10 transmitter screen thus eliminating the need for a battery meter. More importantly, you can set up a predefined minimum voltage level when the DEVO 10 will trigger a sustained vibration alarm so you won't loose track of the battery power or forget to land. You can order this optional feature installed on your X88-J at the time of purchase or you can install this feature yourself at a later date which involve some solder and wiring.

DEVO 10 TELEMETRY INTRODUCTION VIDEO
For Walkera telemetry to function you must have a DEVO 6S, 8S, 10 or 12S transmitter and your helicopter, mulit-rotor or quadcopter must also have a telemetry to gather and transmitter the data. Optional Walkera telemetry module below is available for Devo compatible Walkera helicopters which are not equipped with this function. Helicopters, quadcopters, hexacopters and octocopters using Walkera receivers and transmitters also have similar requirements for the telemetry to work. Walkera Mini CP and Ladybird already come with telemetry, therefore additional telemetry installation is not required on these models. Telemetry module together with Devo RX801, RX802 or RX1002 receiver, can also be installed on any brand of helicopter, quadcopter, hexacopter, octocopter and airplane to work with Devo 6s, 8s, 10 and 12s transmitters. For example, you can upgrade all your helicopters and quadcopters to telemetry including T-Rex 250, 450, 600, Walkera 1#A, Hiko, E-Flite Blades, helicopters larger than 180 size and medium sized quadcopters which has the payload capacity for this module. Take advantage of the newest in RC technology, the optional telemetry module can be purchased below. http://www.wowhobbies.com/walkera-telemetry-module.aspx
