Most KR's, when built to plans, have the fuselage "flare" out at the top making less than a 90 degree angle at the win root, thus a drag creator. I think the RV has pretty much a 90 degree angle at that point. Easiest way to make a fillet is to glass the top of the wing and let cure. Place a piece of foam at the wing to fuselage junction and use a cylinder of some type, soda can, pvc pipe, or other of the desired radius wrapped with sand paper and sand to shape. Having the wing top glassed will keep from sanding the wing foam at that point. Cut kerfs in the foam block so it conforms easily to the wing shape when gluing in place. Should take less than an hour to shape and glass. It doesn't need any flox/resin, just micro if needed for finishing. The fillet also makes it look more "finished". Looks follow function. If it looks fast it probably is. Larry Flesner
