I am building a 1/5 Scale Auster J1 Autocrat from a DB Models kit and have the following dilemma:

I wish to conceal all the Aileron and Flap controls, i.e. no external control horns. Everything must go inside the wing. I thought of Torque tubes running through the wing to the root, but in this aircraft, the root in the cabin area is totally exposed. In other words, no servos in the cabin area. I also intend to do a fully detailed cabin so Servos' there will be totally unacceptable. I am sure that this has been done many times before and I would like to get a few hints, suggestions, links to diagrams or modelers that have done this. Any help would be appreciated.

Thanks,
