Because i have not much experience in flying in Acro mode i am not able to calibrate
the mini in Acro mode.
Like Goofy23 i tried to fly in Stable mode first.
My problem is that after each plugging a new full Lipo, the copter is several degrees
off horizontal level and i have to trim ACC again.
Doesn't the software store the settings from the flight before?
This is really nerve-wracking.
I know you figured out your problem, but yes, ACC data is saved but gyro data is not, so everytime you plug in or turn on the FC the gyro is re-calibrated. Personally what I do is plug in my MW based flight control, then after the battery is strapped in and I can set the copter somewhere still, I will reset it. Seems to work well for me.
