I really don't think so as many instructors and students want an "instant gratification" of model control. The rudder plays only a small part of what there learning as you don't need a rudder to turn a model trainer. Most instructors don't teach it as they never learned to use the rudder. I have a student like this that I am getting ready to pass off. It seems that these people have a mind set that they can do anything if they are just allowed to take control and fly for a few minutes and can keep the model in the air just by boring holes in the sky. In my case the gentleman is 23 years old and gets paid to fly the model. No interest in why the model flies other than he is getting paid to fly it. It's really to bad as the guy has some talent and could be a top notch pilot in the program and if ventured out in the contest circuit, could really give some people a run for there money
