Alex forget about the rudder. You want a small aileron input to produce a slowish roll away from you then time the elevator up input correction at 45 degrees and down at 225 degrees. Work on keeping the roll input steady and the roll rate reasonably slow, I started by using my little finger on the side of the Tx.

The elevator inputs will turn the model in a horizontal circle when you get it right. Concentrate on when to make the inputs and be happy with a stab of up and down. Eventualy you will drop into the right rythmn.

When you get that right try doing one complete roll only in the circuit. YES you will need rudder then.
