I have started on the wing construction. The wings on the real aircraft were constructed from very thin wooden stringers, that could be seen through the canvas covering. I will have to replicate this, and at the same time keep the weight down to a minimum. I have decided to construct the ribs from 2 mm balsa with lots of lightning holes, and then use cap-strips to spread the load from the canvas. Of course I will be using 3mm aircraft grade plywood where strength is needed.

I have also completed the ailerons, but they are not shown here.

Anyway, I will press on with the design. Next is the wing tips and the inner part of the wing, which is made from progressively smaller ribs. When all the wood-work is done, I will continue with the aileron servos and the strut attachment points.
