I have a 450 size elektro heli with Flybar stabilisation.
There’s an APM2.8 installed with Copter 3.2.1 and an external GPS/Compass.
Everything is working so far, but I was testing in loiter mode and it was “Toilet Boiling” heavily.
After some search on the internet I fount that I forgot to do the Motor/Compass calibration.
But when I start the Motor/Compass calibration, I’m not able to run the motor.
To test, I disabled all the pre-arm checks but still nothing.
(In stabilise/loiter/althold mode I can arm and fly the heli)
Does anyone have some tips where to look at to get the motor running in calibration mode?
