Ok. I had a hard landing and broke a couple spots on my wing.. I've stripped the covering and repaired the wing. one of the ailerons broke so I have it off the wing, and the other is still in place. I have a new one to replace the broke one. My question is... Do I need to take the other aileron off the wing or is there a way to leave it on and cover it? And if I have to take it off, do i fill the holes and cut new ones beside the filled holes? And whats the easiest way to get the CA hinge loose from the wing without breaking the wing? thanks..

1. You can cover the wing with the ailerons on. Cover the bottom first leaving about 1/2' of covering overlapping over the aileron. Do not tack it down yet. You will do that
after you cover the bottom side of the aileron. You will use it as a hinge "gap" seal.

Now, cover the top of the wing leaving about 1/2" extra at the trailing edge which will also act a a "hinge gap" seal.

Cover the bottom of the ailerons, first and then the top. Run the covering to the hinge line.

Now, go back to the botttom of the wing. Deflect the aileron down as far as it will go and then seal the trailing edge of the wing. I use my trim iron and iron the covering
down into the hinge line and then seal the remainder down on the aileron. Turn the wing over and deflect the aileron as far down as it willgo and do the same thing.

2. Removing CA hinges is relatively easy. Just get a nice new exacto blade and carefully run it into the wing or aileron (whichever has the remaining hinge)
parallel with the hinge working the knife back a forth loosening the balsa from the hinge. Do the same on the bottom side of the hinge. Generally, they will come
right out. If the slot has been enlarge a lot you can move over and redo or use the plastic pinned hinges. They are thicker and will take up a lot of
the slack. You epoxy them in. Be careful not to get expoxy on the pins.

Rehang the aileron simply with new CA hinges with new slots move over just near the old ones, do not remove the old ca hinges just cut and sand. smooth. You do not have put the hinges in the exact same spot just near the old spots. This works absolutely fine and will do an easy and clean job.

I sometimes trim the covering so it will slip into the aileron hinge gap by notcthing around the hinges.

thanks guys, I just looked over RCKens Sig LT 40 build , and I think I got it now... He did a really good job with the build and explaining......
