Well.. i have no problems with AP. But then.. i also dont think about it :noexpression:
Its almost like a 2nd nature to me. If something wrong, i check if route mode is active, center the ruder, chk AP buttons.. a bit of trim.. and off i go! :smartass:
i barely use DM too.
Edit :
Yeah, same here. That red switch never did anything useful to me. Always land on the belly :P
