Since the fuse construction is exactly like the 50cc Giles with the two wing tube locations (scale and on the thrust line) I know I would cheat and use the upper location. Make this plane a mid-wing design and it would be a real monster and likely have even less coupling.
Just speculating, but it sounds interesting.
That was the idea, some people care more about how it flies than about the scale-ness. BTW the upper tube is not quite on the thrust line but is much closer than scale.
