QUADCOPTERS, HEXACOPTER, OCTOCOPTER & DRONES

The convergence of multi-rotor RC helicopter and lighter camera technology is sparking a new era in aerial videos. Recognized as the leading choice for aerial platform, quadcopters are now transforming the exciting world of aerial videography. Fueled by ever increasing demand in stability and payload, hexacopters and octocopters will eventually replace all super-sized RC helicopters as the more reliable and safer way to take professional aerial videos. Multiple counter rotating rotor blades and state-of-the-art 3-axis gyro offer outstanding stability with extra payload capacity. Beginner pilots no longer need an extended training period associated with standard RC helicopters which are much more difficult and dangerous to fly. Multi-rotor helicopters are also inherently more camera friendly because its centralized camera mount between taller skid landings help retain its center of gravity. By using the basic quadcopter as an example, we can easily extrapolate each subject to cover both hexacopters and octocopters in general.

QUADCOPTER ARCHITECTURE

RC Quadcopter or quadrocopter is a multi-rotor design utilizing 4 rotors/propellers instead of the single or dual rotor systems used in more conventional helicopter designsQuadcopters' counter rotating stability is similar to co-axial helicopters but with much more power and efficiency. Without the torque associated with traditional single rotor designs, quadcopters are much more stable and easier to fly. If you are a photographer with little or no experience with RC helicopters, a quadcopter is often a great place to start. Traditional single rotor helicopters utilize the tilt of the complete main rotor mechanism to control direction. Then to counter the torque from the main rotor, a tail rotor also control its yaw. In comparison, quadcopters varies the speed of its 4 motor to control roll, tilt & yaw. With recent advances in high quality sensors and gyros, the motors for the rotors will automatically adjust to maintain a leveled flight for self-stabilization. To increase or decrease height, the pilot simply move the throttle stick (left stick for mode 2 operations) up or down to increase or decrease the speed of all 4 rotors. To turn the quadcopter left or right, the pilot moves the yaw stick (which is the same as the throttle stick) left or right. Pulling the stick to the left increase the speed of clockwise rotor #2 & #4 thereby increasing the quadcopter's counter clockwise torque to turn the quad left. Doing the opposite will of course result in the quadcopter turning right. Moving the directional stick (right stick for mode 2) down increases the speed of rotor pair #3 & #4 which tips the quadcopter forward to increase forward movement. Doing the opposite increases the speed of rotor pair #1 & #2 which increases backward speed. The same applies to rolling the quadcopter left & right by speeding up the corresponding rotor pair #1 & #4 or rotors pair #2 & #3.

The quadcopter flight controller serves as the central station where all incoming information is processed. A quality 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. The quality of auto-stabilization function depends greatly on the quality of the attitude sensor and how the data is translated into instructions for the electronic speed controller which in turn drives the brushless motors. Even with proper instructions, it's still up to the power of the motors and rotors to overcome any instability during flight.

A quadcopter's aerodynamics is quite different than that of an airplane or even a helicopter. Since there are no wings used for lift, extensive horizontal surfaces represent a significant liability. This is especially critical when a quadcopter is descending when motors are slowing down.

Another variable involves the quadcopter's weight to surface ratio. A heavier design can only be partially remedied by more powerful motors. On the other hand there are plenty of problems associated with lighter designs too since they often lack the structure integrity to carry heavier payloads. The best optimized designs require a well structured hub that serves as a bracing system for the arms. While using small diameter booms for shorter arms is perfectly adequate on smaller quadcopters, similar structures on  larger quadcopters or octocopters is often insufficient. Larger system such as hexacopters and octocopters with a sandwiched thin boom design is often too weak to carry heavier payloads. A thicker "waffled" center hub system similar to a network of "I" beams offers much better support. Another solutions involves the implementation of braces to reinforce individual arms. An easy way to do the structural "flex test" is to tie one to three pounds of weight under a quadcopter then hold any two opposite motors and measure how much sag results under the center hub in the process. Warning, do not attempt to hang too much weight under a weak structure.

QUADCOPTER DEVELOPMENT AND ITEGRATION

Structural consideration are often overlooked because the designer did not accommodate for sufficient payload on the system. Multi-rotors with larger wing spans such as hexacopters and octocopters require better reinforcements to stabilize longer booms/arms. Elaborately molded plastic structures often leads to excessive weight which can not be remedied with more powerful motors or larger rotors. Even with years of experience, Quadcopter developer usually spend months in researching components, learning how to program and adjust flight controllers, then debug the individually assemble unit. Without adequate resources, many quadcopter operations never progress beyond a home based operation. Because quadcopter is such a dynamic product, establishing multiple sources for consistently reliable  parts can be a real challenge. For example, hub covers are often improvised from flimsy clear plastic domes or inadequate acrylic or carbon fiber strips that might pass in a brochure. In reality, the hub will become unmanageable with the necessity of additional components and wires. To meet higher standards, a professional developer and manufacturer must invest in both development and production. Leading edge designs are most successful when the originating developer incorporate the best available flight controller technology while maintaining direct manufacturing control of all other components. Flight controllers require constant updates and upgrades which are suited to flight controller specialists such as DJI, X-aircraft and Mikrokopter. Open source Arduino flight controllers might be a tempting format for individuals who are interested in adding customized features. But in most cases these features can be accomplished by integrating existing components from third party manufacturers. Sub-contracting out components such as frames, CNC parts, motors and ESCs increases cost and reduces the ability of the developer to control quality. In other words, a BMW mounted with a Ford engine that uses a suspension system from Toyota is not a good idea. But it make perfect sense for Dell computers to use a Intel processor.




HOW TO SELECT A QUADCOPTER OR DRONE

How do you find the best quadcopter? What should one look for to narrow down your search? Here are several important factors that you should consider.


QUADCOPTER CATEGORIES (DIMENSIONS & TOY/HOBBY/PROFESSIONAL GRADE)

Please note that quacopters are categorized by its dimension which is a measurement between motor shafts located on any two opposing arms. Further differentiation are based on quality of components used. The integration of brushless motors with ESCs is one of the main feature of higher end hobby & professional quadcopters. Trainer helicopters usually employs more economical brush motors which do not require ESCs. Smaller brush motors works very efficiently for these smaller quadcopters but are too weak for larger systems. We shall cover these differences in the ladder part of this article.
  1. Micro Trainer Quadcopters: 4-8 inches (e.g. Walkera Lady Bird, E-Flite MQX, XCopter) 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.
  2. Mid-Size Trainer Quadcopters: 12-20 inches (e.g. Draganflyer X4, Walkera 5#)
  3. Mid-Size Hobby Quadcopters: 12-20 inches (e.g. Walkera MX400, Gaui 330X/S, Gaui 500X/S, AR.Drone, Arducopter) Most of these quads have enough payload capacity to carry a small camera such as the GoPro or Cyber-Shot.
  4. Full-Size Professional Quadcopters: 24 inches approximately (e.g. Turbo Ace X830-S, Lotus T580, Turbo Ace X720, Lotus T380, AX650-K/R, CX650-R)

Please remember that some of the above models are fully assembled and tested (Walkera Lady Bird & MX400, the Turbo Ace X830-S, CX650-R). Some are just kits (Gaui 330X/S & 550X/S, AX650-K) which require assembly and testing. Further more many are not complete systems which require receivers and transmitter radios (Gaui 330X/S, & 500X/S, AX650-R, CX650-R).


QUADCOPTER PARTS & COMPONENTS

Let's separate the boys from the men. Although this is not a guarantee - the quality of the motors on a quadcopter is often an indication of it's quality. More expensive brushless motors are lighter, more powerful and extra durable compared to traditional brush motors. The wire in brushless motors are hand-wound so they can not be mass produced. Further more each brushless motor are driven by ESC (electronic speed controller) which are too cost prohibitive for smaller and cheaper quadcopters. 

OVERALL PERFORMANCE IN STABILITY, MANEUVERABILITY & WIND RESISTANCE

There are several factors that disproportionately affect the performance of quadcopters. Weight to power ratio and the sensitivity of the attitude sensor determines both power and stability. Aerodynamics and propellers size determines how the quadcopter handles windy conditions. Sometimes the effect is counter intuitive. Despite some common claims, larger propellers with lower RPM may actually reduce stability because a larger surface is exposed to the wind.

THE CAUSE AND EFFECT OF IMAGE STABILITY & VIBRATIONS ON VIDEO QUALITY

When you are looking for high definition video quality, image stability and vibrations are 2 separate issues. Image instability is caused by platform movement while vibrations are mainly a result of motor and propellers rotation which may be amplified by oscillation.

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 some of the movements. Continuous signals from the on board attitude sensor or 3-axis gyro in combination with your transmitter input both effectively tells 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 and later utilize. Even with the best camera mount, you will still see some residual movement 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. There are also more sophisticated stabilizing software which will can easily cost as much as the quadcopter or an expensive camera.


On the other hand even the quickest multi-axis camera mounts and the smartest stabilizing software can not neutralize vibrations in your video. This difficult problem needs to be addressed at several different levels. The source of the problem starts from the quadcopter motors and the rotors. A well balance motor causes less vibrations. Some motors are dynamically balanced such as the TA-X830-04 on the Turbo Ace X830-S. Motor can only be balanced at the factory with a special machine. Similar to balancing a tire, each motor is mounted and spun at high speed and small amount of solder are added to a few selected edges of the motor drum until the rotation is completely smooth. As for the propellers, a similar procedure can be used to balance them with an inexpensive blade balancer. Since perfectly balanced propellers are not critical to the operation and stability of the quadcopter, it’s often left as an optional task for the end-user. Finally, even with properly balanced motors and propellers, there will still be some vibrations present. The last stand to isolate the vibration from the camera is the camera mount. Most camera mounts do not have adequate vibration dampening features. This will be a paramount issue if high quality video is your goal.


There are other factors that might adversely affect the quality of your video. For example, have any carbon material or structure under the rotating propeller can cause distortion in your video. To eliminate this possibility, one should avoid quadcopters with carbon arms/booms extending below the propellers. Have addressed all features on your quadcopter, you should not overlook some basic concepts in selecting a proper camera mount or gimbal.

How can such a simple device play a critical role? Well, having a super stable quadcopter without a good camera mount is analogous to using cheap tires on a race car. Even a the best engine can not overcome flat tires. A inferior camera mount will substantially amplify any undesirable shaking or vibrations. First figure our how many axises you need the gyro to auto-compensate and how many axises you want to access 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 drives the structure which pivots on 2 or 3 axises. 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 in a integral part of the pivot design (ALA3CMV2) 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 which move on 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 strong quadcopter or the additional lifting capacity of a hexacopter or an 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 lifespan 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.

TURBO ACE X88-J OCTOCOPTER (Single Flight Controller)
 
TURBO ACE X88-J comes in a RTF (ready to fly) package. To reducing shipping size and prevent damage, propellers and landing skids are dismounted after individual flight test and prior to shipping. End user can easily re-install them in about 15 minutes. In general, an octocopter offers a smoother platform for heavier payload than hexacopters and quadcopters. And because there are more motor in multiple directions, the X88-J offers a certain amount of redundancy. With some practice, a pilot can quickly and safely land if one of the motors fails. In similar situations, hexacopters and quadcopter will not be able to compensate for such failures.

X88-J FEATURES
 
* Super Rigid I-beam Structure, at 4.3 pounds without the battery, is an extraordinary lighter and more powerful structure than outdated weaker and bulkier designs based on sandwiched booms and plastic molds. The exceptional X88-J frame features (1) a central carbon fiber hub anchored by 4 pairs of radiating carbon fiber I-beams that will not sag and bounce under heavier payloads (2) shorter and lighter aluminum arms that extend out to the motors significantly reduced weight around the parameters for exceptional maneuverability (3) spacing within I-beams provides a propeller cooled locations to secure ESCs (4) sturdy CNC mounting locations at the end of each beam facilitate an extra wide landing skid (5) foldable joints for portability, traveling and shipping. Traditionally an I-beam structure is not required on quadcopters. With smaller wingspan and lower payload quadcopter can easily get by with weaker smaller diameter tubes.

* Care Free Home Lock Flight Mode
utilizes the octocopter's take off home position as a reference point for orientation/heading. The pilot no longer needs to maintain a tail-in (tail towards the pilot) orientation to keep track of the octocopter's heading. Pushing the cyclic stick up will always result in the helicopter flying forward and away from the pilot. Pulling the cyclic stick down will result in the octocopter backing up towards the pilot which in turn provides a very reliable "come home" solution. Similarly the roll (left & right) controls will correspond to the pilots home position without any mental acrobatics. Although the pilot can still use the yaw to turn or spin the octocopter, it will not affect the pilot's flight orientation from the home position. After activation this Home Lock mode will be effective when the octocopter is beyond 30 feet from the take off position. The Home Lock mode is the most convenient and preferred mode for pilots who like fly facing the octocopter.

* Care Free Course Lock Flight Mode
utilizes the octocopter's initial take off heading direction as a reference direction for the duration of the flight. For example if the octocopter and the pilot's transmitter is facing north in the take off position, the octocopter will always treat the north as the direction (heading) for forward flight even if the yaw has rotated the front of the octocopter to a different direction. After activation this Course Lock mode will be effective when the octocopter is beyond 30 feet from the take off position. The best way to use the Course Lock mode is to keep the transmitter facing the initial take off heading direction during the entire flight even if this means the pilot has to turn his head to see the octocopter.

*
GPS Lock
enables the X88-J to lock into a self sustaining hover at GPS location with a flip of a switch on the transmitter. Even when the octocopter is pulled away from its locked location, it will return to that original location. This a very useful and precise locking function that operates within a few feet (about 1 foot vertical and up to 6 feet radius) depending on the quality of GPS satellite signals and the flying environment. Generally speaking, the GPS system on the X88 is much more sophicated and precise than GPS on smaller quadcopter units. Without specific applications, GPS features on a quadcopter is usually not very effective.

* Dual Stage Fail Safe Mode
offers a backup plan when the octocopter receiver looses connection with the transmitter. When this occurs, the octocopter will automatically return to the point above the home GPS position. Hovering at about 60 feet, the pilot may be able to re-established connection and manually land the octocopter. If connection is not re-established, then the octocopter will automatically lands in fail safe mode. Also, if the octocopter battery is low, it will start an auto landing sequence before it runs out of power.

* Dynamically Balanced Brushless Motors
reduces high frequency vibrations at the source. This technology was successfully integrated on the X830-S quadcopter which is now adapted on the X88.
* 35A ESCs with Cooling Algorithm offers extra capacity for continued operation without cooling off periods between flights. This is another feature that was originally used on the X830-S quadcopter. However, the X88-J has 8 of them.
* Foldable Arms for safer transporting and traveling.
* Professional Aluminum Carrying Case is customized to fit the foldable X88-J.
* Modularized Design for ease of maintenance and repair.
* USA Parts Support for fast and easy continued access to parts, upgrades and accessories.
* Optional Telemetry for transmitting updated battery voltage readings to the transmitter (for DEVO 8S/10/12S only)
* Optional 2 or 3-axis Camera Mounts for a variety of cameras and camcorders.
* Optional Automated Gyro Compensation for the camera mount: Requires a secondary Xaircraft flight controller and 3-axis gyro.
* Optional Dual Pilot with secondary receiver and transmitter for the camera man.
* Optional single way point and multiple way point GPS with PC connections can be purchased separately.

FEATURES VIDEO QUALITY:
To improve video quality, the X830-S quadcopter features precision dynamically balanced motors that are rarely offered in multi-rotors. Balanced motors greatly reduce the common vibration problem that causes poor video quality. Due to high rotor speed, the exceptional vibration dampening X830-S super structure is the key in reducing harmonic vibrations. The X830-S is designed with video quality in mind. It utilizes aluminum tubes and ABS body instead of carbon fiber that generates interference, causing wave lines on the video. Example of video distortion, notice the word "COUNTRY". Goto http://www.wowhobbies.com/250seinstruction-2.aspx 
The X-830-S video are sharp with no wave lines and they also have no jello effect caused by high frequency vibration generated from unbalanced motors.

FLIGHT STABILITY:
Turbo Ace pre-configures the X830-S so it is most wind resistant and at the same time gives you maximum auto stabilization by utilizing 2 custom preprogrammed flight modes, cruise and hover. This type of custom configuration often takes days to tune in a DIY (Do-It-Yourself) kits. 
 
DURABILITY:
The X830-S dynamically balanced motors have been re-engineered to take multiple mild crashes. Instead of round or screw mount propellers, X830-S quadcopter propellers are rectangular key mounted on the neck of the motor bell which eliminates propeller slippage and significantly reduces the probability of accidental propeller dislodge. Offering another benefit, this updated rectangular key mounted design completely envelopes a thicker motor shaft to prevent it from bending in 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-S 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-S is based on a maintenance friendly design. Independent modularized components can be easily removed and replaced. Connectors are strategically placed to simplify disassembly and reassembly. Customized CNC quadcopter components offers better alignment while reducing the amount of parts used. And due to larger volume, X830-S 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-S 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. 
 
COOLING: The X830-S quadcopter is highly reliable, it uses four 35A ESC with cooling algorism that can carry heavy payload with super low motor/ESC temperature. The unique placement of the ESC on the X830-S is 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-S 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 and PAYLOAD:Turbo Ace motors are build with high efficiency stators and they are over 20% more power than its Xaircrasft quadcopter contemporaries. Please take into consideration your flight time, performance, pilot ability and safety when loading up your X830-S. The X830-S 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-S 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 it's 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-S 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 vibration, 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.
