Hello, You will find the rudder is needed for take off too. On mother earth, the ailerons have no effect. If you have a nose wheel it will be connected to the rudder servo. Lets say you need to correct right while the wheels are on the ground, the nose wheel will be doing the turning. As you pick up speed on take off, the rudder is also in the right correction mode and it will take over as you leave the ground. NOTE: As speed comes up, even on the ground, the rudder will become increasingly operational. As you leave the ground you "MAY" not need the "right" correction anymore. You can then go back to neutral on the rudder stick and by then the ailerons will start taking over. I mentioned "right" a lot. Most planes will want to wander left from the torque of the engine on take off. I had a BIG, BIG, problem while learning. I usually OVER corrected creating a lot of laughs from the pits as I criss-cross the runway!!!! .. lownslo
