I just got a an Align T-Rex and bought a new DX6i tx/rx to go with it. I have an older used lipo and fired it up and got it flying, when I got a servo flutter, my rear servo started fluttering on its own and then threw itself all the way down causing my heli to crash bummer....I've since tested it out on the ground and sometimes(not always) i'll get this servo movement without any input whatsoever. What could cause this? I know that my lipo isn't good anymore for long, but I still got it in the air with it, but could my rx just not be getting enough power?

When you say 'rear' servo do you mean the tail servo?

danman_83

I mean the elevator servo I believe...the rearmost servo controlling the swashplate

Ok. If you move that servo to another channel on the RX does it behave? It sounds like it may be a bad servo.

Were these new servos that came with your radio or were they on the heli? (ie used)

They were used...hi tec hbs65..i haven't tried changing channels with it yet, i'll give it a shot and let you know what happens...the problem is that it only does it occasionally
