The wing uses a center plywood rib extension keys to hold the front of the wing to the fuselage rather than the dowels used on the MonoKote ARF and kit. The wing platform is the same size, airfoil and shape as the MonoKote ARF and kit. I did not cut off the back edge of the wing tips on my kit. The wing ribs are cutout on the front and back of the wing spar area all the way to the wing tip. I do not recall seeing that on the MonoKote ARF and I know they were not cutout in the kit. The wheels have a plastic hubs and foam rubber tires.
