I have been having problems with my mostly newly built quadcopter. It flies ok, but not as responsive as I think it should. After auto tuning, I get a lot of problems. Ive experienced problems with two Flight controllers, apm 2.6 and a pixhawk.
Main problem that occurs, almost immediately after I land and disarm after Auto tuning, is that the quadcopter would rotate/yaw uncontrollably to the right.
At 1st I thought it was the apm 2.6 being faulty..bought a pixhawk. Same thing happened with the pixhawk, I assumed an esc was faulty, bought a 4 in1 esc...same thing eventually happens. Usually the rotation will start after I disarm and save the autotune, and try to get back in the air. This time...It flew up nicely in the air..then 2 mins later...began to spin.
Whats happening here?

I had this kind of problem with APM 3.2 on a new build carbon fibre Hex. Worked flawlessly hand tuned - but Auto Tune wrecked the PIDs, they were all over the place.
It feels to me like AT has broken in 3.2. I won't risk it again until I read of any successes with it (not read one yet!!).
Everything else in 3.2 has been fabulous.

Same problem. My hexa rotate by yaw with constant speed and drift. Pixhawk 3.2 firmware
