Duh.. now that you point it out, it's obvious to me. So one servo per aileron, but with dual inputs to each (elevator and aileron). So it can serve as both aileron or elevator depending on my inputs. Cool.

At least I don't have to build that darn mechanical mixing tray (and that saves some weight as well as preserving my C of G).

When I measure the C of G, should I have the tank half full of fuel or full or empty??

Thanks, /S.
