check it out and let me know what you guys think of that, this aileron came out of the box with a curve on the side where it needs to attach to the trailing edge of the wing. I allready glued the shaft that goes in the aileron with 5 min epoxy and i am about to glue the inges in place.
should i go on like this or get a new aileron? Am i to picky?
thanks

I would contact the manufacturer and ask for a new one and shaft. Using that one is asking for flutter and, indirectly, a crash.

i just sent them an email... but... we're friday.. so i guess no news until monday.
But is there anywhere else i could work on the plane even if i'm stuck there?

contact horizon hobbies and request a new wing set. the one you have is unacceptable and a crash would be inevitable.

This is ONE of the reasons for test fitting several times BEFORE applying glue. Once glue is applied it complicates things.
I assume you are calling the aileron torque rod the "shaft"??
Did you use epoxy on the torque rod? If you have a covering iron (household iron in a pinch) heat up the area near the torque rod and it MAY soften the epoxy enough to remove the aileron. Use a twisting motion instead of a pulling motion as soon as able.
Check the aileron and the wing trailing edge with a reliable straight edge to see which one is crooked. Perhaps both.

it's only the aileron that is crooked...
but yes i should of think of that before applying the glue.
i dont think i have any room to fit some kind of iron there.
what about the CA debonder?

A CA debonder won't have any effect on epoxy. Heating it is really your only option. I would just ask the manufacturer to give you another one as well.

Let's see. It's already been suggested that he get an aileron so that can't be it.
Torque rod? Nah, that can't be it. Thats built into the wing and he'd probably destroy the wing truing to change that.
The whole wing? Now that would be silly to expect Hobbico (or whoever) to replace all that because he failed to check the part before installing it. Yes, yes I know it should have been straight in the first place but the assembler has to accept SOME responsibility IMO.

He said he epoxied a shaft into the aileron. If it's a torque rod that gets threaded into the wing, replace it with the aileron rather than ruining the shaft trying to get it loose.

That is a pretty big gap, but I have seen airplanes fly with worse. I think what I would do, since you have already epoxied the torque rod into the aileron, is to go ahead and CA the hinges in and then seal the hinge gap with some clear tape.
To seal the gap, here's what you do. Get some clear tape that is at least 1" wide (like packing tape) and cut a piece as long as the aileron. Now set the wing upside down and flex the aileron downward as far as it can. Then carefully fold the tape lengthwise with the sticky side out (it doesn't have to be actually creased, but bent as much as convenient). Now the tricky part. You will stick the tape down into the gap between the aileron and the wing. Try to work it as far as you can down in the gap. A small screwdriver and/or a popsicle stick will help push it down and make it stick. Might take a couple tries to get it in straight.
Don't despair, it can be done. Actually, it would probably work just as well to do the tape in 2 or three pieces.
You can do both the bottom and the top sides, but just the bottom is probably enough. You do the bottom because that's where it will show the least. Doing the top also will help keep dirt and fuel from loosening the tape.
When you got the tape in there good, flex the aileron back and forth to make sure it moves easily through it's full range.
If you want, you could use the Monokote trim sheet instead of clear tape. This has the advantage of being in different colors (although it will probably not exactly match your colors) and it also comes with adhesive on it with a paper backing. You can cut a long strip, fold it with a good crease, peel off the backing and stick it into the gap. Good luck!

You know, it occurs to me that if you don't want to try sealing the gap and want to put on a new aileron, you could just cut that old one loose. Just cut through the wood where the torque rod goes in. Then you could try to get a new aileron from the manufacturer. Of course, make sure they will send you a new one before you destroy the bent one.
Also, don't use 5 minute epoxy. It doesn't give you enough working time. Use 30 minute instead.[8D]

yeah, i think i should just wait and see what the company says. I dont remember who said to use a iron but i think it's a great idea... but i would need to be the one that is like a big pen to burn wood, if it fits in there.
This is my first plane, well i bought it with my father and i just dont want to rush to build it. Of course, were probably gonna crash it !! ishhhh cant think of it! lol

Actually ho2zoo had the best idea for removing the aileron if that is decided upon as the way to go.
Just (carefully) cut the thing off. Probably end up with the torque rod with a clump of epoxy on it. This can also be carefully removed until it looks like new.

the rod or shaft that is epoxied is, i think, the same rod that comes out underneth the wing wich we get the rod to connect to.
This rod was just fit in a hole made by the manufacturer and epoxied it was not threaded in.
i'll give you a picture so we all talk the same language.

Your best bet is to try to do this without changing the torque rod. There are many ways of removing the old epoxy from the torque rod if it comes to that.
