Hi all, I have a new 600N with a JR770 Gyro with 8900 servo. The problem is when I backflip to inverted the heli yaws to the left just slightly. Its no major problem but just annoying that I have to make adjustments evry time I back flip. Forward flips appear to be good. Im using a Futaba 9c. Gyro has been set up in rate mode to find neutral, end points are at 140 with dual rates on rudder set to 70% and expo set at -60. Ive gone to -60 on expo thinking it was me yawing slightly as I apply elevator (mode 1)but this is not the case.
Gyro mounting tape is good and also have a velcro tie down holding it.
Engine tuning is good (os50).
Any ideas on what might be causing this drift during backflips, or should I start again with gyro setup.
