I did the exact same thing already by putting in a torque rod and install a servo inverted on the bottom of the vertical stab. All linkages are totally concealed. You could almost do the same thing for the elevators too.
I'm pretty much on hold right now waiting for the wing tubes so I can finish the wings. Everything else is pretty much done so I have started with the primer and putty on the fuse. It is pretty much going faster then I thought it would and when I finish the fiberglassing the wings its all downhill from there.
