Walkera 4G3 Ultimate Combo Pack: No expenses have been spared in customizing this creme de la creme of the Walkera 4G3, a "Turbo" Double BL Helicopter that offers twice the power of the current Walkera 4G3 Double BL Helicopter. At the heart of these powerful upgrades is the Turbo Ace 81220 main motor and the 2.9g dual bearing tail motor which are fully synced with the Rx, the coverter and the ESCs. To optimize performance, reliability and durability you need the right combination of components, skilled integration and extensive testing experience and Wow Hobbies is uniquely qualified to bring you this exclusive 4G3 package to save you the trouble of having to study and go over hundred of posts in the forums, then experiment & shop and assemble this ultimate 3D machine.
Not only have we integrated the ultimate 4G3 helicopter we have also provided top of the line peripheral components and extra Walkera 4G3 parts for your convenience. The Turbo Ace 81220 brushless motor is matched with a 20T brass pinion and the 2.9g brushless tail motor is mounted on a super-light weight carbon tail stand with exclusive motor locking clamp. Extra parts include a set of main blades, tail rotor & 5 batteries. We test flight all our helicopters (actually put them in flight) and log it after we have completed the test. Because this Ultimate 4G3 helicopter package is customized in California using a long list of premium components and it may take an extra working day to be ready.
Note that 220 volt version of this combo is available, just order this item and email me after you've checked out so I can change the charger to 220V. The only difference between 110V and 220V versions is the charger.
Why is the 2.9g brushless tail motor is a better choice than the Walkera 2g tail motor that comes with the stock Walkera double brushless? We carry both motors and we think you should know the difference when you are paying extra. The 2.9g motor has about 50% more torque/power and it comes with double bearings verses the 2g with no bearings. The bearings greatly prolongs the life of the motor! The Walkera 2g Brushless motor is extremely weak and will only sustain about 2 crashs verses the 2.9g brushless motor which rarely breaks after multipe crashs. Here is a video of the ultimate Walkera 4G3 Turbo Double Brushless in action.

The ESC used in this video is Walkera's newest BL tail ESC with built-in converter. Our test has shown that the Walkera tail ESC performs equally or may be slightly better than the Flea. Two thumbs up for Walkera's newest tail ESC/converter. It is extremely fast in tail data update and the tail stays very solid, see video
Overall performance with 2.9g brushless tail motor and Turbo Ace 91416 brushless main motor
This ultimate double brushless heli includes 2.9g V-shape tail motor carbon fiber holder/stand, motor-locking-clamp, 2.9g BL outrunner motor and the newest Walkera brushless tail ESC with build-in converter. Though this 2.9g BL motor & V-shape tail holder set looks similar to other sets available else where, it is not the same in the way it secures the motor. The Wow Hobbies 2.9g motor & V-shape Tail Holder set is secured togehter by an exclusive Wow Hobbies locking clamp making it easier to remove for service and almost impossible to break off during a crash. Since most other 2.9g motor & V-shape tail holder sets are glued togehter, the motor are most likely to pop off in a crash. Even if you didn't loose the motor in the grass, it is still a hassel to repeatly glue the motor back in place. And for other more complex tail holders, the additional plastic cage or lock used to secure the tail motor put extra weight on the tail which is absolutely the worse location to throw the helicopter out of balance.
Please note that it is equally important to match the 2.9g brushless tail with a more powerful main motor such as the Turbo Ace 81220 high performance Thermo cool outrunner BL motor. You can think of a powerful main motor and a powerful tail motor as a paired set. Getting one upgrade without the other usually causes an imbalance. All of Walkera's stock motors including main & tail and brush & brushless motors are all too weak to make more advanced 3D manuvers. For the 4G3 main motor, Walkera has used the same weaker brushless motor used on the 4#3B which resulted in motor stalling in a hard bank and when you try to upgrade it to a 16T it often cogs during startup. Instead of redesigning a completely new stronger motor, Walkera has chosen to step down to a 12T pinion to band-aid the startup problem. Consequently, the current stock double brushless heli is still lacking both in torque and KV during 3D flights. Turbo Ace 81220 has been designed from the start with high performance 3D performance in mind. It not only provides much more power but also features smooth start technology with increased KV using a 16T pinion. The combined result, the Turbo Ace 81220 produces over 100% more lift than stock Walkera. See video on how the Turbo Ace 81220 motor integrates with the 2.9g brushless tail to the stunning performance:
Important! Buyers beware, when you purchase a double brushless heli, make sure that it comes with a locking device for the tail motor, either locked by screws or a locking clamp otherwise the tail motor can easily be dislodged from vibration or a crash which results in a total damage of your BL tail motor.
Here are the reasons why Wow Hobbies is the best value for your helicopter(s) purchase.
1. All helicopters are tested at our warehouse in Shenzhen, China before air shipment to California USA. The factory QA transparent label outside the box is opened at this checkpoint.
2. All helicopters are re-tested at our warehouse in California. An actual hover test is performed, gyro is checked during flight in normal and stunt mode and a visual inspection of the helicopter is conducted. A green QA label is affixed at this checkpoint. Also a battery installation instruction that has been ignored by Walkera has been affixed to ensure a trouble-free setup.
3. Wow Hobbies resets Walkera WK-2801 radio default setting for throttle hold from +12% to -5% for the safety of your flight.
4. Instruction manual for the Walkera programmable WK-2801 radio can be very difficult to follow. Wow Hobbies has included a set of quick setup instruction that will resolve many of the setup issues with this programmable radio.
5. Finally a no DOA (Dead on arrival) guarantee by Wow Hobbies which protects you from shipping damages.

Brushless outrunner 81220 Features
This 81220-4G3 motor will only start properly when the 3 motor wires are soldered directlly to the Walkera ESC. Do not use connectors! The shorter the wires are from the motor to the ESC, the better the motor performance. If the motor turns in the wrong direction just desolder any 2 wires, swap them and solder them back to the ESC. Thou this motor is the same as the 81220-4G6, the depth of the pinion is different, it has been adjusted to fit the 4G3. If you have a 4G6, you need to order the 81220-4G6 with the proper pinion depth for the 4G6.
Coming soon! Newest vidoe of 4G3 with the latest HP08-2 brushless outrunner motor.
The newest Thermo cool Turbo Ace 81220-4G3 (HP08-2 With 20T Pinion) outrunner brushless motor for the Walkera 4G3 with more torque and lighter weight than the stock Walkera BL motor. Outrunner motors have inherantly higher mass moments of inertia and linear momentum that offers extra punch and prevents stalls. Like a car with more horse power the 81220 enables faster acceleration. Like a world class gymnast, a lighter aircraft is also more nimble and responsive. You can say linear momenutum is beneficial inside the motor but not in your over all flight mass.
Operating at 120 degrees, the 81220 temperature is 15 degrees cooler than 4G3 stock brushless motor. Premature bearing failure are often associated with exccesive heat and ineffecient use of battery power. The 81220 provides exceptional lifespan and extended flight time. There is no longer any fear that your motor will burn out because you didn't wait long enough for it to cool off between flights.
Important Instruction: The Turbo Ace 81220 (HP08-2) is optimized when the 3 wires from the motor are soldered directly to the Walkera main ESC. By doing so, the motor will run stronger, less likely to cog and will not stall during startup. Directly soldering the wires to the ESC will result in shorter wires and no contact points. This type of installation is a little inconvenient for maintenance since you can not unplug the motor as easily but it reduces the resistance of the current from the ESC to the motor allowing the motor to operate at its optimum state. If the motor runs in a reverse direction, just unsolder any 2 wires, switch them and solder them back to the ESC.
