The Camel ailerons are done completely wrong at the "factory" in China. I learned the correct way to hinge with iron on covering from the instructions for building a "Wild Weasel", from RCM plans.

For starters, the angle cut is on top, and it should be on the bottom, but this can be lived with.

Secondly, the builders used one piece of covering on top and one piece on the bottom and covered and hinged at the same time, that's why the ailerons are so reluctant to move very much, particularly "up", which is what we really need on a bird like this, so we can crank in a lot of differential to make it handle nice.

After cutting them off, start by putting the aileron in the down position, and flipped right over 180 degrees so that the flat surfaces are parallel, and use a bit of tape at each end to hold it to the wing. Then, iron in a strip of OD covering between the tape bits.

Next, flip it over and move the aileron to full up, using tape to hold it there.

Iron on the white strip on the roundel first, followed by the gray, then the blue.

Voila. Aileron moves to max deflection in both directions.
