Hello, I'm new to quadcopters and have just completed my first build. My quadcopter is built on the H.AL. Frame with a KK2 board updated to ver 1.6 from Hobbyking. My maiden flight was a week ago and although it flew well, I experienced rudder drift to the left. Throttle, elvevator/airleron input seems to have no effect on it, nor does self level being on or off. The rudder trim on my radio doesn't fix the problem either, 1 click of right trim makes the rudder drift right, 1 click back and it drifts left again, etc. No true center can be achieved. I was wondering what, if any, P or I setting can be adjusted to fix this problem. Btw, I have a cheap radio from Hobbyking, a 2.4ghz 4ch I picked up for $25, it seems to work okay as an entry level radio for learning. If it wasn't for that annoying rudder drift I wouldn't have any complaints at all with it. Any advice would be much appreciated, I'm not against maybe purchasing a better radio with more precise trims if that would help.
Thank you
