I'd need to go and look at the plans again to be sure, but I think it is pretty darned close. The leading edge of the stab is raised quite a bit, a-la full scale. Of course the wings are probably not exact scale in incidence, as they have a flat bottomed airfoil instead of an undercambered airfoil. But like I said, the airplane flies really well. Very maneuvarable, and not difficult to fly at all. Take offs are quite easy with the big rudder able to keep the nose straight. Landings are interesting as with any Dr.1 model. There is a sweet spot on the approach speed that if you hit right, landings are a breeze. Too fast, and the model tends to bounce a bit and get tipsy laterally, which means one of the wing tips will contact the grass, and then around she goes! Two wheeler landings are the way to go. Trying to flare into a three pointer just results in a stall with the drag of those three wings at high angles of attack. I've flown the model many times now and have the peculiarities figured out. It's not hard to fly, just a little different.
