OK. Since I was a young lad building balsa stick, rubber powered planes, I've yet to build a straight fuselage.

Just completed a 1/2A kit with a crooked fuselage...I pinned it all down, made sure it was straight, then glued. The next morning when I unpinned it, it looked good. A couple hours later it was bowed!

I'm thinking of building a 40 sized Kaos (tower kit), but i'm worried about all that work just to have a crooked plane.

I hear some kits inter-lock and can't be built crooked...but for the ones that aren't designed that way, what can I do to build it straight?
