"For my planes and copters I usually create "truth tables" that I print out in paper (so that I can revise them before flying and have them at sight), but you could also create small stickers for your transmitter. This is an example for my X8 copter…"

"Yes, I will thoroughly check it from now on. In this case since both ailerons and rudder were reversed I didn't notice the issue in the quick -bad- checks. Thanks a lot for the reply and tips!"

"Hello,
I had the exact problem with my plane (Skywalker/Aero with Pixhawk and APM:Plane 3.3.0), I hand-launched it directly in AUTO mode and after a couple of seconds gaining altitude it went UPSIDE DOWN all of a sudden and kept going like that...…"

Note that I meant APM:Plane 3.3, I mistyped 3.3.2
