Hey guys,
So I think I got to the bottom of my issue, but I’d like to know what caused it. You were onto something with trim, but it was in the APM radio calibration rather than on the transmitter!
So below is a screenshot of me carrying out a RC calibration. Min/max throws of the sticks look pretty normal, all about the same. However when you dive into the RC1-RC4 parameters, the RC2_TRIM value is considerably different to the others. Manually writing this to 1480 gets the hex working nicely, takes off, holds position in the air well, and no tipping over!
Running the RC calibration again sets it back to the ~980 region though. How exactly is this trim value derived in the calibration process?
Cheers for the help
Chris
