So, I overtightened the wing a little and heard a small crack.
There's a hairline crack through the wing mount in the fuselage. Whats the best fix? Remove and replace or will epoxy/CA fix?

Other than that, had a great day of flying today!

What plane? Can you post some pictures? You could probably scab over and redrill the holes for the wing nuts...

It's a tiger 2. It's a tiny crack. I'll try to get some pics up tomorrow. Its not the entire mount, just the front side of it right through the middle to the blind nut.

Just put some thin CA on the hairline fracture, and scab a piece of light ply on the back side with think CA and you should be good to go.

Put some light oil or vasoline in the blind nut before you glue so you don't mess up the threads. ENJOY!!!

Yesterday I repaired a cracked wing-mounting block by drilling two holes across the crack and using round toothpicks as dowels. The holes were through the covering and a nail set was used so they would not show through the covering patch. A liberal dose of CA was used on the crack and toothpicks.
