Default filets on plug in wing

Is it possible to make fillets on plug-in wings ?

The wing would have to have a constant rib thickness (i.e., no taper toward the wing tip), and the wing tube would have to be parallel to the top surface of the wing. Otherwise, the root rib would not be able to slip under the outer edge of the fillet. Alternatively, I suppose one could build the filet on the wing itself rather than the fuselage but one would have to be creative to make the fuse/fillet seam look OK when looking down on the plane.

My thought would be to build it up on the wing. Easy way would be to put wax paper on the sides of the fuse and build up the fillets up to what you want using slow cure epoxy mixed with major amounts of micro-balloons. When the epoxy is cured, touch up as needed with a fine grit sandpaper and paint. Obviously, the wax paper is just a release agent so if you know of something you'd rather use, us it

Hydro has the right idea, but many use Monokote in lieu of the waxed paper.

The covering is applied, and the waxed. After the fillet resin cures, the covering is removed.

I place the fillet on the fuselage, and cover the wing, in the fillet area.

That's why I said, if you have something you'd rather use.....................................
Glad to see someone actually likes something I suggested. Usually, it's more of a "say what????????????" reaction that I get

I found the answer to my question. Posting info for others.

This will ad a little to the overall wingspan unless you cut the piece directly off the wing (talking about an ARF wing mod)


I will ad the extension to the fuse and leave the wing alone. It' easier that way if the plug in tubes are already installed (ARF mod)

That's a pretty slick way of doing it. Alternately, you can start the fillet with the 1/32 plywood on the fuselage, then plug the wing in and put a layer of balsa or filler up to it that you feather out for a few inches.

I would think, as shown, the filet should be on the fuse. it's easier to build the filet and better to keep the filet on good shape.
