I’ve built a multicopter based on F450 frame with pixhawk4 and this is my first flight:
I have 2 problems I need help with. First one is the pulsing of thrust. I’ve found a section in https://docs.px4.io/v1.9.0/en/flying/basic_flying.html that mentions it might be related to Land Detector configuration, however I have no idea what to change and how to safely test my changes afterwards.
Which leads me to the second problem - the drone only wants to fly up! How do I make it descend? I was able to “land” by a pure luck - when switching to Stabilized mode the motors went to minimum thrust so by switching back and forth I was able to land. I have FrSky Lite, mode 2, both stick autocenter by itself.
I’ve gone several time over the px4 and qgc docs now. From the beginner point of view, I would appreciate a more step by step approach that would lead me to the first fight.
