I took my APM2/Y6 out for its maiden today. At first, it seemed ok, a little wobbly, but this is only with a few PID iterations. Something just doesn't feel right though. After some forward flight in stabilize mode, if I return the elevator to neutral, the copter will pitch back drastically instead of levelling and if I try to give it forward elevator to resume forward flight, it will barely pitch forward. I am giving it full forward elevator but the copter is still basically level. If there was more than a 5mph headwind, there would be no coming back.
I take it my stabilize gains are too high, but I don't understand why it attenuates my elevator input so drastically.
I also set up my gear switch for RTL and the planner shows the correct mode when I switch, but nothing happens even after verifying I have a solid blue on the GPS.
