I'm currently trying to setup an APM 2.6 for my tricopter. I've flashed the firmware, but can't calibrate the accelerometer. I've checked and found the 3.3v regulator is working, but for some reason it's just not calibrating.
Can anyone help?
Edit: Also whenever I look at the flight data artificial horizon, it just drifts about and just responds weirdly to any movement of the apm.
