sorry I was not trying to hijack I thought the thread discussed if a heli is "really RTF".
It is a gaui 200 SE pro that is set up with all the electronics and tested by Flying Hobby . anyways even with a fut 401 gyro and an se frame with DX7, the heli will hover solid for a few seconds then without warning the tail will jerk which is a big deal on a little heli. I know how to program the gyro and it appears to be mechanical.
