True scale is not important to me in the least. What is most important is how the plane flies. I'd love to know about the different configurations available.

My thoughts at this point:
There is a thin support running lengthwise about 1 1/2" from the back of the wing. I was going to cut out the wing behind that support starting where the center-wing sheeting ends (like the lower aileron) and create an aileron by adding balsa to the front of the part I remove. The cross-support is thin on the top wing, so I was going to add balsa to the back of it to beef it up.

To couple the top & bottom ailerons, I was thinking of adding an eyelet to the top of the bottom aileron and the bottom of the top aileron, and running a pushrod between them.

Is that the way it's done?
