If you had klett hinges to do that there was something wrong with the hinge cutouts.I've used klett hinges for over 20 yrs and have never had one to fail.Your control surfaces had to be misaligned causing severe fluter for that to happen.There is a club member who has a giant bud nosen p-51 with klett hinges and it's flown on a regular basis.This plane is 14 yrs old and has never had a hinge to fail.All I'm saying here is there was something you over looked or did not notice when you were assembling the plane.Don't take this the wrong way but it happens to the best of us.I have a hanger 9 limited edition cap 232 and a elevator half was out of alignment.I did'nt notice it until I was checking the throws.Needless to say I had to remove the elevator half and install balsa plugs in the trailing edge and drill new holes for the robart hinges
