First make sure all your controls are going the right way. You can reverse the channels on your radio if not. There are instructions for the kk that tells you how to reverse the gyros by turning off one of the pots and selecting the channel to reverse. Dont worry about the motor stopping or starting, it will sort itself out in the air.
If anyone is interested in my friend Alf's aluminium H-Quad design the forward to about 6min 30sec for a quick look. Its an awesome design but he still needs some blade balancing.
