Also tried a hobbywing v2 speed control, worked for a few metres, and then nothing......
has anyone had any problems with their graupners. I heard something about bad soldering on the Graupners sensor board....
check the soldering, but also... put a piece of electrical tape around the sensor board (cut out where the bearing goes) I found I had to do this with a 17.5 as I had the same issue as yourself.
