I have repaired a broken CA type hinge with the control surface in place.

One thing is for sure, you cannot put the new CA hinge exactly where the old one was. It has to be beide the original spot.

My observation on my high flight time planes with broken hinges, I considered it to be my fault because I had too much CA on the hinge causing it to break.

They typically break at the control link in the center or at the tip. They rarly break in the center.

Enjoy,
