Hi, I recently just completed my build of a qavr2 and I have a problem when landing or bumping anything. Whenever my quad bumps into, for example when I cut power to land and it hits the ground, one or more of the motors goes crazy and the quad freaks out. I don't know which motor or motors but I took off the props and simulated landing by touching it on the ground and I can hear one motor spin up and down crazy. If I had props on, it would fly all over. I am running dshot 600 8k 8k. I have tried dshot 300 4k 4k with no difference. I have reflashed blheli 32.7 and reflash bf 4.1. The only other reason I can find is my ESC is faulty, which means I have to unsolder and resolder my whole quad! I have a 4in1 ESC. xilo stax f4 processor. Any suggestions are helpful!
