I expect the full scale had them and in this size model an HXT900 (9gr from Hobbyking @ $3/ea) in each wing could be easily added I think

Thanks for the detailed math John. My old maths master, 'Spider' Beck, would be proud to know that I understood all of it. And he wouldn't even let us use a slide rule or 'guess stick' as he called them, calculators would have given him apoplexy!.

I have seriously thought about adding ailerons and I think it would be possible to do it with a single servo in the fuselage but I'd like first to see how it flies with just rudder / elevator in case there is a weight issue. I could build a second pair of wings later with ailerons and the possibility of using them as flaperons to more closely simulate the STOL performance of the full size.

I'm feeling a little sad as I'm in the last stages of serious balsa bashing - just a few more bits of 1/8"square to complete the elevators then it's all down to sanding, doping, ironing and wire bending.
