RE: CP Drifting to left????
It's something you need to get used to on a dual rotor heli. The tail rotor thrusts to the right to counteract the main rotor torque. since the gyro tries to hold the nose straight, that right thrust from the tail translates into a left drift.
Sorry. Wish I could have given you better news. The only way to fix it is to add trim on the transmitter, or adjust your swashplate to tilt very slightly to the right. I suggest you just get used to it. It's something you adapt to pretty quickly.
