Fastsky hit the nail directly on the head... a "COMPETENT" instructor does not wait for the student to tell him to take control of the aircraft. I cant count the times in my first few flights where my instructor said "I've got it", and I didnt even realize that quickly that I was in trouble. His competence and attention to what was going on with the plane at all times saved me from re-kitting the plane several times, I suspect. There is a big difference in getting instruction from someone who knows how to fly R/C, and someone who can "instruct" flying R/C. I've flown full scale for a bunch of years, and the same holds true in that relm also... just because a pilot can fly does not in any way mean he is competent or qualified to teach someone else to fly.
