Folks I just took a pushrod off the bottom of my stick out behind the rear of the front spar to a crank mounted at the wing gap off the front WAF bolts; thence a second tube back within the gap to the aileron lug. The latter has a slight bend in it to go over the lower rear WAF. There is a very slight movement of the rods as the stick is moved fore and aft but it's so slight you don't notice it in flight. The angles imposed on the rod ends are easily within the limits of the rod end bearings. Works well and is so simple and maintenance free compared to the cable system. The location of the bearing ends attach holes on the the cranks will determine the aileron differential in a way similiar to the conventional rear mounted cable derived system.
