Use those little rudders on the canard. Should give plenty of rudder authority. That will couple with the dihedral in the wingtips to give some roll control. You could also rig the wing for wing warping, like the Wrights used, to get direct roll control. Use the rigging wires between the trailing edge set of interplane struts. Find a book on the Wright's airplanes to get the details.

It's debatable how much good the rudders between the wings are doing, although they don't hurt. I'm not surprised that you didn't get much rudder control from them. OTOH, if you remove them, you might find that the plane is quite happy flying sideways, with little or no yaw stability.

Apparently the original airplane was a MODEL (8' 6" span, NOT full-scale) and a free flight, so control response probably was not an issue. The record was a flight of 51 seconds in 1914, which presumably could have been in a straight line. For your R/C model, doing turns or otherwise being able to steer it would not necessarily be a "scale maneuver".
