Hey all, I am working on a little pusher project and want to tuck the engine into the rear of the fuselage 12-16" rather then put it up on top, or hanging way out the back. Engine options should be anything from a 912 to a Yamaha, to a Suzuki/Honda. The obvious problem with that is that it does not leave a good structural place to attach the rear spar.

The plan is to use tube spars of some sort. Either a big one like a Kolb or a pair of 2.5" or 3" front and rear spars. My first thought was to move the rear spar in, and put a false spar on the back to mount the ailerons to. Has that been done before? I really don't want to go off the reservation here. I am trying to stick to proven construction techniques.
