I was hoping someone could shed some light on a problem we are having with our quad-rotor.
We are trying to tune our quad-rotor and we have it where is can fly well in stabilized mode. The issue comes when we try to put the quad-rotor into Altitude hold mode. The quad-rotor either just shoots up into the ceiling or it oscillates a lot like comes all the way down to the ground and then back up.
Here is a flight log from one of the flights.
Our setup includes custom quad-rotor, terraranger lidar, px4 flow optical flow and pixracer flight controller.
Also we were wondering if there is a way to completely remove the barometer from the state estimation? We tried using the LPE and unfuse the barometer, however, the quad-rotor would not arm without having the baro in the state estimation.
Any help is appreciated thank you.
