I just upgraded the motor on my Trex 550 to the KDE 600xf 1100kv. I'm running a17t pinion and a talon 90amp ESC and 90mm tail blades. Under any cyclc except slow and smooth I am getting a nasty tail kick. I have tried adding pre-comp but that didn't seem to do anything to solve it. Any ideas I could try?

Thanks,
Chris

Flybarless? Which controller, if so?

Sorry thought being in section I was in it would be assumed it is an AR7200BX. One other thing I didn't mention that might help. I am running in gov mode with a head speed of 2100.

A few more questions. What transmitter are you using, and what channel do you believe is controlling the rudder gyro gain? The AR7200BX will expect to see gain controlled from channel 5.

I'm running a dx8 and the gain is on channel 5. I'm running 60% gain in fm2.
