The last 2 times I have flown my TF (red box) P-51B Mustang, I noticed CA hinges were broken. Once, 2 of the 3 on the aileron and now 1 of 4 on the elevator. Luckly it has affected flight although I'm still mystified on the aileron. I have been using CA hinges for 9 yrs and no problem. Is some CA hinge material better than others????? Also, on this plane I made a extra efffort to minimize the gap and got thin CA on the portion of the hinge that bends. I'm sure I have done this before, anyway, is that a no-no ??????????????
