Well, hello! Yes, aeajr, the sailplanel is a scale model one of thee most innovative airplane... EVER! It was the very first aircraft with a stressed skin 'D' tube wing. All subsequent aircraft owe a debt of gratitude to this design. 3-views were used from Martin Simons' book 'Sailplanes 1920-1945'. Thanks again, Martin! The full scale version had a wingspan of 12.6m so my 1/4 scale version is 3.15m. The ailerons are activated by a crank inside the wing. Since the crank swings an arc there is a 'slider' on rails that engages the crank arm. Thus the ailerons are the warping variety and mine functions per the full scale. Modern parlance would be that the wings 'morph' for roll control. It has since been mostly covered but the ply skinning can't go onto the fuselage until I finish molding the wheels. It has three. They resemble beach balls.

I thought I'd get more views and/ or responses by now. My goodness... look at that ugly thing. Thank you for being the first responder with a question, even!
