Introduction:
Following the development for shaft driven helicopter from Walkera, the newest additional to Walkera model lineup is the UFLY. A shaft drive medium size helicopter with aluminum alloy rotor head, the usually RTF configuration with all necessary accessory included (battery, charger, radio, etc), brushless motors, etc. As shaft driven tail driven tail offer better rudder control compare to separate tail motor system, it should make this little heli quite stable for both indoor and outdoor flying.
Preflight check:
As usual in Walkera fashion the helicopter come 100% build and tested. And well protected inside coloured box. Battery and chargers were included. After charging the battery during the bench test I notice the swash is slightly forward. One turn with the elevator push rod fix this issue. Another good point about this kit is it come with brushless motor and full aluminum rotor head already. No more burn out brushed motor and the aluminum head make the heli more crash resistance and slop free for longer service life.
Flight test:
As expect for a FP helicopter it is quite stable. The initial setting there are slight tail hunt, simple fix by decreasing the gyro gain by around 5min and everything work flawlessly. The heli fly really nice and does it’s job nicely. One thing I don’t like about it is the blades. They are made by the same materials as the cb180 which do offer some flex but will break during hard impact. It would be nice if Walkera can replace it with materials which flex a bit more so it would be more crash resistance.
Conclusion:
Nice RTF heli. If you are like me which is very lazy and what to fly it as soon as you get it. Try this one. It is very simple to setup and fly. And due to it’s medium size it can be easily flown indoor, but not too small so it is still very stable and can fly outdoor if desire. The only thing I don’t like about this heli is the blades and hope Walkera can improve on this in the future.
Pros:
RTF
Very stable tail
High quality construction
New 2402 LCD transmitter
Brushless motor and lipo battery
Cons:
Plastic rotor blades
Slight tail hunt with the initial setup
