I too got an Axe Cp two months ago. I have replaced quite a few parts including tail rotor, main rotors, and a few other head parts. I have installed a Blade CP tail rotor, Blade CP flybar paddles and wheel weights on the flybar. I also purchased the LiPo batteries. It seems that if I allow the main rotor to spin up for a few seconds and stabilize befor adding more collective, I don't have the drift to the left quite as bad. Or I am learning how to compensate for it. I fly in a 12' X 12' area in the basement but try to keep it in a 6' circle, gives me 3' to play with on all sides. I also found that to keep it in somewhat of a controllable hover, I am moving the right stick quite a bit, almost full travel. Is this normal and is it due to the extra weight on the flybar. I was imaging it would take small adjustments on the right stick to keep it in a hover, not moving the stick in a rather large circle. I do have FMS but find the Axe to be easier.
