Hi Norm,

I did not notice any problem at all with the controller. I actually borrowed this controller from a friend - until mine arrives. He set it up and I believe must have done it correctly because the performance was good. Prior to plugging in the pack, I set my transmitter throttle-cut switch on (this is the lowest channel 3 setting). Plug in the pack and hear a series of beeps. Turn off the throttle-cut switch wich yields a low idle. Then raise to full throttle and back to idle. Then take off. This was the recommended procedure and it worked just fine for me. No problems.
