I was taught to fly Models (before PPL.) by a National Aerobatics Champion. We mostly did circuits, and he was extremely critical of any loss of height in the corners, even 1ft was frowned upon... So that taught the basic 'Bank and Yank' technique.
For the landings or T+Gs, we learnt to control the descent rate with throttle, which is a bit counter intuitive to a newby. Also the use of the trimmers was learnt, so that the model could fly 'Hands Off', much the same as in our Cessna.
There are some model flying skills which don't translate to actual flying... The ability to judge Left and Right when the model is flying away and then towards, and making a straight line to a displaced runway, for instance.
My model flying Instructor was quite a perfectionist, and this delayed my passing of the Test, but I was quite happy to have him standing next to me, if only for the company.
