Ah, I see.

I guess the thickness of the wing would have to effect how you put the servos in, huh? I think if it were me, I'd try and put them right outside of 1/3 the way out the wing if they'll fit there...

FHH does tend to be on the money... and he hit both of what I'd call your best options: if it won't fit in the wing, into the fuse with torque rods is probably the way to go. I wouldn't want to mess with bell cranks (each presents three extra places to introduce slop), and I guess I prefer torque rods to flexible pushrods. Just don't want to allow much extraneous movement or flexibility in the ailerons of a plane with a pretty hefty power loading.
