HI all.....I have been fooling around with my walkera 22d for a few weeks now and I have to say.....the helicopter mechanics are great but like eveyone else has said.... THE ELECTRONICS SUCK.... NOTHING BUT GLITCHES......AT FULL POWER THE SERVOS SORT OF TWITCH AND ITS ALMOST IMPOSSIBLE TO CONTROL. Any ideas why it is doing this? Also I have a Hitec Flash 4 computer radio that is new in the box.....is the any servo, reciever, gyro units that I could use on the walkera to make it better. I would like to use the new radio as opposed to buying a new one. PLEASE HELP DAN
