I'm a flight instructor in full size airplanes. I am however, new to remote control airplanes. I encourage my students to fly with different instructors to find one they really like. Some instructors don't like it when I fly with their students, but I don't care if any of my students try a different guy. He might do some things better than me, and if I really suck I will find out quickly. I haven't lost any students to other instructors yet.
