I have Matek H743-slim, M9N-5883 GPS and I am using 4.1.0 beta v5. I am using H type drone. Drone weight is 1700 gr. I am using Racerstar AirA 2508 1200KV motors (quadcopter) and 6S 5200 mAh battery.
I have some problems. Firstly when I using auto mode, my altitude is not fixed. I try block barometer, using sponge but not work. And I can see altitude is downing but my drone not fix this. What is my problem?
