I am using the PX4 Mini from Holybro for my homebuilt quadrocopter.
It is flown in Stabilize, Altitude and the Position Flightmode. Flown. Stabilize and Altitude works great, clean flight behavior. If I then switch to the position mode, the flight movements become hectic and unsteady. If I give pitch forward, it picks up speed and then in between again and again every few meters jerky braking maneuvers. I have already worked a lot with the PID values of the control, but I can’t get it to work. The behavior also occurs with the roll axis.
It is as if the control impulses from the GPS are too strong.
Is there perhaps a variable with which one can influence the access of the GPS?
As ground station I use QGroundControl with which I have loaded the PX4 firmware stable version 1.11.2. I would like to load another version of it, unfortunately, this does not seem to work with QGC. When loading the firmware, only this one path is displayed.
From another forum I learned that with this FC from Holybro also Ardu firmware works. Unfortunately nothing happens when I mark Ardupilot in QGC.
Does anyone have an idea about this?
