http://www.spadtothebone.net/SPAD/si...torversion.htm that is another method of going with not mixing. A torque rod from the ailerons to the centre and then a horn on the elevator works. I haven't really tried it, but seen it on "For What It's Worth" a long time ago. The Spad To the Bone site has a bunch of cool stuff too. I am just making a couple right now. Saturday night Midget with a .15 should be a hoot.
The control surfaces were taped on only for the mock up of the first one to get the control movements and geometry correct. The actual finished hinge line was the iron on covering. One inch wide the whole length of the control surface ironed on top and bottom. The aileron leading edge needs to be shaped tapered to the top edge for top edge hinging. I lay the aileron upside down on the top of the wing lined up edge to edge and iron on the one inch bottom strip. I then flex it down to maximum down holding it edge to edge and iron on the one inch top strip. When I cover the rest of the wing I do not go over the hinge again but cover up to the hinge line. No binding works like a charm never had one ever come apart even in the most violent of mid airs.
The University of Windsor liked the performance of the flying wing design so much they used the same configuration with a different airfoil for heavy lifting to compete at the Lockhede Martin SAE Aerodesign contest

On this model as well it was the covering that provided the hinging.
