RE: Which plane would an instructor fear the most?
The Mustang. Yes, I have heard stories of people bringing them as well to the club, but never saw that happen personally. On the simulator, I found the Mustang PTS in full sport mode with no training aids to be more of a challenge to land than the Great Planes (Top-Flite) version. It likes to bounce, unless I add full down elevator after the mains touch (is it different in real life?). Good throttle management and a shallow approach is very helpful here. It will spin with too much elevator while coming in too slow and steep. Too much rudder in a steep bank will make it drop like a rock.
How about a Christen Eagle or Cap 232 in comparison?
