I've almost finished my first quadcopter. I've used a KK2.0 board. I've followed several guides online to program my ESCs and set up the KK2.0. I'm noticing a few things that I can't seem to fix though. Perhaps you clever people can help?!
When I switch the quadcopter on, there are four simultaneous beeps from the ESCs/motors. After a few seconds, one of the beeps starts to go out of sync with the other three. Is this a problem/sign of anything? I've checked the ESCs are programmed correctly and redone the KK2.0 setup several times.
When I arm the KK2.0 and push my throttle forward (propellors still off at this point!) the motors kick in. But say for example I push the throttle to around 30%, the motors start but one (the back right - the odd beeping one) starts to speed up further after a few seconds. Tilting the quadcopter makes the correct motors speed up etc. What could be causing this motor to speed up to full speed slowly?
Cheers for any suggestions!
