CC 10 trouble

[Tele]

ok what couls be causing the axi motor to emitt a whinning sound when the throttle goes up?

I have upgraded to the new software version and ever since then the soun d has appeared. its only when the motor is under strain as in throttling up. its almost as if the timing is out some what ..its not as good as it was before..
what are other peoples settings fro a cc10 and the axi motor?

cheers doug
