I'm a professional pilot and have been flying full scale for over thirty years. I've also been involved in model airplanes for over 45 years, and r/c for the past 25. I think the only place the full scale helped me in r/c flying is that I understood take offs, landings, and aircraft maneuvering. I find that when I teach students, it takes a while before they understand the concept of "flying" the airplane. But, I don't think my hand/eye coordination was any better than anyone else. The best students today are the video game kids. Unbelievable coordination. They will make awesome full scale pilots someday!
