Hi, I was installing new Graupner radio in my ElectroHub Y6 and playing with motor calibration and setup, no idea what I've done but now I can't calibrate the ESC's, for some reason 4 of the six motors are starting mid throttle, which seems to be arming them, as I move the stick up and down the rotation of the motors changes as well! I think I need to somehow reset ESC's to default, however I can seem to even enter the program mode. Any suggestions would be greatly appreciated. Cheers
