RE: Tail drifting in Idle Up
also if you want to have two different gain settings in only one mode you can do that as well by setting gyro sensitivity to say:
0=92 (84% gain in Heading Hold Mode)
1=95 (90% gain Heading Hold Mode)
or
0=8 (84% gain in Norm mode)
1=5 (90% gain in Norm mode)
hope this helps clear it up some for you.
