Hi, I am building the Kadet LT-40, and put the left wing and airelon together. After I was finished, I noticed the airelon extends past the wing end by about 1/8" of where it was if it was perfectly lined up. How much of a problem is this. Also, when I flex the airelon directly, it takes a bit less work then when doing it by the torque rod, again, is this not normal?

Thanks.

Hi there!

Your ailerons probably look too wide now because when you installed the hinges, you had to leave a small gap between the wing and the aileron to allow the aileron to move. I woudn't worry about this, it's merely cosmetic and as soon as you stop worrying about it you won't notice it any more!

As to your second question, if you "flex the aileron directly" I assume you are doing it from the trailing edge (back edge) of the aileron. Moving the aileron from there gives you a much better "lever" than the torque rod is using, as it is located right at the hinge line, so it will be easier. You should be OK. Install you aileron servo and hook up your receiver/battery etc. If your servo can move the aileron to it's full deflection and return to centre without buzzing or otherwise complaining you are good to go.

Most importantly, have a veteran check your plane out thoroughly before it's first flight!

Have fun!

Thanks for your response, but I think you may have misunderstand my first question. i mean it extends past the wing tip, as in if you look at it from the back it goes to the left past the wing tip, not the space between the back of the wing and the beginning of the airelon.

I remember in the directions when I built mine, you had to cut that off and "round it" so it was flush..

The biggest problem with having the aileron sticking out past the wingtip on a trainer is that just about everything you try to go past will snag on it, and try to rip the aileron off. If you cartwheel, you can be pretty sure the aileron will take damage.

In the air, it won't affect anything on an LT-40.

On faster planes, an overly long aileron like that can contribute to flutter, but that's really the worst of it.

Looking for a clarification. So would it be a probable problem, or should it not be. Thanks for indulging me.

Shouldn't be a problem. Go fly.

You might want to trim it to keep stupid things from happening (transport damage, etc), but I'm sure it's airworthy and it won't cause a crash or dangerous situation, so you can fly it.

I would just trim it off and sand it rounded so it looks good and re-cover the end of it.

Have someone go through the plane before you fly it and make sure everything is set up right. Have them help you fly it if you haven't flown before as well.
