Anyway to see if it's perfectly calibrated it need to stay still in ATTI mode with no wind, not in gps mode
Thanks for the advice. If there is ever a time when it isn't windy here, I'll check it out. The times I've flown in ATTI mode it didn't behave abnormally. It reacted exactly as I anticipated. If the calibration was off by too much, one should be able to sense that even in a 5mph crosswind. I'll try to get it flying in a no wind condition to be sure. Living on the Coast, that's hard to find.
