RE: Your best building blunders! ...post em' here.
I have two:
The smallest of the blunders was I accidentally glued the torque rods of the ailerons with CA and had to rip off the entire trailing edge and redo.
The biggest blunder to date is while I was building my Eaglet 50 I accidentally sat on the fuselage I had set aside. Totally destroyed. The rest of that build is still in the cellar waiting for a scratch built fuselage
