Dragonfly Problems
 

I just received my dragonfly and i cant wait to fly. but when i initialize the chopper and turn on the transmitter sometimes the aileron servo just jitters serverly. other times the tail rotor motor runs nearly flat out. the elevators and main rotor controls are unaffected.

I bought the all inclusive chopper with the Zhen Hua PCM Xmitter on 35mhz. anyone with any help?

You should always turn the transmitter on first.

I normally turn the transmitter on first but this doesn't change the situation

I swapped the aileron and elevator over on the board the the aileron servo continued to jitter indicating it was the servo. i cleaned the pot up in the servo but this only helped for a short amount of time.

the tail motor also spins up without command.

Could it be interference? Aircraft and choppers in Australia operate on 36Mhz, and i'm on 35Mhz at the moment.

It could be interference, but most likely it is a bad transmitter or receiver. The quality control on those Chinese products is not always the best.

Can i change the freqency of the unit by buying new 36Mhz crystals and installing them? will the gear need to be re-tuned?

I have 2 Walkera Dragonfly #4's and both of them started doing the same thing after about the 3rd or 4th battery charge and it's only the aileron servo effected. Today the jittering got worse until the the servo just quit working all together, so I swapped it out with one from the other heli and it still had the jitters but worked for about 5 minutes then it quit also. Now I don't know what to do, I'm afraid to swap it out with my last good servo if it's just going to burn it out too.

I also have a Walkera Dragonfly #4. Both servo's started to jitter and in the end locked up completely (Luckily on the ground). The best thing you can do is bin the standard servo's as they are very cheap and buy some decent ones. You don't have to spend that much and it totally transforms the way the heli flys.
