I wish I could have gotten in on this earlier, but just couldn't due to computer problems and starting a Job in Madison, AL.
Anyway, at WAM contest I used to attend If someone was flying a stock Magician, you could watch and hear the stabalizer both flexing and making a buzzing sound in a hard inside or even outside corner. I was always afraid that one of the stabs was going to snap resulting in a rather spectacular crash. Never did see one, but it still worried me!
