So I got done straightening the hinge slot. It's a looser fit now with the Hangar 9 CA hinge, but there is clearly still contact with both sides of the hinge... it doesn't just fall out in other words... only that the wood isn't squeazing it as much as before. Suppose I could let it settle a bit for a while in case the balsa "fluffs out" again somewhat.

This particular slot is on the side of the widest part of the aileron... but that is also next to the fuse... I guess the force felt during flight by each hinge should be roughly equal anyway.

Anyway, not much else you can do I guess.

I won't be doing anything extreme with the plane... just basic lazy aerobatics, patterns, so I guess it's no biggy if that one hinge isn't perfect.

I'll still look around for those thicker GP CA hinges. If I use those will have to recut the apposing aileron slot as well, because they really are a fair bit thicker (and more "fuzzy" ) than the Hangar 9 ones.

Thanks for the help
