I have an AR7200BX on my Trex 550E DFC V2.
I have been flying this setup at least 50 times without any issue. She is stable and hovers very steady without any stick movement (centered sticks).
Set-up:
Tail pitch slider set-up is centered at 90 degrees/perpendicular to the tail shaft with about 10mm tail rotor differential to correct for tail right/nose left movement.
Observation:
After initialization of the BX, I typically hit rate mode to center the tail slider, put her back in HH mode and spool up gradually and right before mid stick I throttle up and take flight.
However, I recently noticed (never paid attention to this before) if I leave her on the ground/concrete while I spool up to about 50% idle and a bit negative collective pitch (about 2 degrees), the tail slider may move to the left (tail left/nose right) without stick input. This does not happen every time.
If I correct for the movement she will stay centered and hold there indefinitely.
Question: Any ideas as to what is going on here with the independent slider movement?
