Hi, I recently built a quad flys super nice in stabilize mode when I switch to loiter mode the quad will hold steady for a second or two then begins to fly around the loiter point increasing in speed around the point. I've tweaked the loiter pids and hold_lat_p and hold_lon_p. any suggestions for the pids settings for a standard 3d robotics quad? Also should I be adjusting the pids in the "full parameters" menu or the basic pids? Thank you.
Reset all of your PIDs to defaults then go do everthing in Randy's excellent Arducopoter 3.0 Pre-flight and Maiden-flight videos. In particular, you need to do compassmot to fix your toilet-bowl problem, not change PIDs.
I did the compass to test in the setup in the cli. I got 186% at full throttle. The video says anything over 30% should look into moving the 2.5 apm. So is 186% not good? I'm putting my other 2.6 apm with the external compass on because the PDB wires r not long enough to move the 2.5 far enough away from the board. Any thoughts or comments greatly appreciated and thank you.
