IMO- in my opinion. There used to be an acronyms list here in the begginers forum, I learned alot from it. As far as your banking problem - how long of a flight did you have? You might just be dealing with P-factor. The torque of the engine at low airspeed will cause the plane to bank to the left. Try keeping the plane on the ground longer and build up more speed before you lift off. Also, since the rudder is in the prop blast and the ailerons aren't, the rudder is much more effective at low airspeed. Try giving right rudder as well as right aileron. Good luck.
