Mike is correct. I have never restrained my Impact from the stab. Always in front of the landing gear. Furthermore, I never snapped or even spun the model. I didn't take pictures of it, but last night while examining the stock rudder I noticed indents on both side in the front of the rudder that line up with the edges of the back of the fuse. It could be cause by the rudder hinges flexing. I used real Robart hinge pins and not the ones that come with the model. The indents could also be caused by the rudder hitting something while I was carrying it in and out of the basement. I also carry my planes rudder first.

Regardless of all this. I was extremely lucky to be able to successfully land the airplane with no damage to any of the internal components. I am not going to take the chance of repairing it and having a catastrophic failure. Anyone need wings or stabs?
