Funny you should mention that! The prop hanging was quite fun and I have had the plane pointing straight up at a standstill or turning either direction. It never occoured to me to point the plane down in a dive!! I would have been more concerned about the rubber bands on the wing popping off rather than the engine overreving! BTW, I trained my kid and some 2 of his friends on the LT before I sold it. Now I wished that I kept it and made it into a twin!
