Hi folks,

I'm currently building my first plane - a kit built Sig Kadet LT-40. I've got the wing built and have just cut the hinge slots into the wing and ailerons. The problem is, the right aileron seems to be warped along its length i.e. when I test fit it to the wing the middle of the aileron buts up against the middle of the wing TE, but either end of the aileron shows a gap of 1/16" (or 1/8" at the outboard end if I make sure that both the inboard aileron end and the aileron center are tight against the wing TE.) Basically, the aileron is slightly banana shaped!

Is this aileron salvageable, or should I (1) attempt to correct the bend (if it's even possible), (2) replace it with a new aileron or (3) don't worry about it, it'll be fine!

As a follow on question, I cut the hinge slots with a Du-Bro hinge slotting kit. The slots are the correct width and depth, and are cut dead-center in both the ailerons and the wing TE. My concern is that the slots may be a little too loose fitting for the thin Sig easy hinges (the hinge cutting tools are quite a bit thicker than a #11 blade.) How loose is too loose for hinge fitting, and should I just upgrade to some pin hinges instead?

Thanks for the help,
Neil.
