Let me ask you a question. Do you have a full size pilot licence? How many hours do you have flying real aircraft?

No doubt you are an accomplished RC pilot with a wall full of trophies. But without any real flying experience in real aircraft, how do you know full scale aerodynamics and techniques don't work in RC aircraft?

You missed my point in mentioning Frise ailerons, The OP asked "What is adverse yaw" I explained it and also described ways it is minimised in any aircraft, full size or models, IE Differential, (where I agreed with you) and Frise ailerons.

Sure you are right that not many RC models have Frise ailerons, but that does not negate the fact that they are a valid design feature to reduce adverse yaw. Again, am I technically incorrect in saying so?

Remember this is a beginners forum, how many beginners do you see on a typical weekend learning to fly in a perfectly set up aircraft with no roll / yaw coupling?

We are talking about learning the foundations correctly, once that knowledge is in place, then the pilots can experiment with aircraft and piloting techniques that expand the flight envelope beyond anything a real aircraft is capable of.
I'm not saying that full scale techniques don't work, I'm saying that they work differently and can't always be laterally applied. You are correct, I am not a full scale pilot, I do have a few hours in a C152 but that's about it. I grew up around airplanes, my father was career air force and I took all available aviation classes I could all through high school. Still I admit that my full scale knowledge is limited. My comments are based on years of seeing full scale pilots getting into R/C and then setting up the airplanes to operate much the same as full scale and then struggle with a model that could be made much easier to fly. That brings me to your last sentence. Shouldn't that foundation include teaching a beginner to to trim flight his airplane to be as easy to fly as possible? Correct me if I'm wrong but my perspective is that with full scale you simply accept that it has certain characteristics because there is really nothing you can do to change them. A good example is that full scale aircraft has to have slightly forward CG to accommodate passengers and/or cargo. Our models CG should be more or less a fixed position so we can adjust it to more a neutral position and reduce the need for pitch trim adjustments considerably. I'm simply saying that taking a different approach to models as opposed to full scale will lead to a better model pilot in the long run.
