The fillets are strips of blue foam stuck on with 3M77 and sanded with paper wrapped around a dowel. A minimum amount of spackle is needed, but the foam blends to the wood very nicely. A coat of epoxy to seal the foam goes on next ... <snip>...I think the finished weight will be well within what a pair of .074s can carry vertical
Ain't foam great!!?? I've been using it more and more and building a few foamys. It works so easily and if you screw up, it's not like losing $3 of wood and 30 minutes sanding; more like 3 cents and a few minutes of work time. My primary building tool is an old fashioned carbon steel butcher knife.
I can visualize that plane flying horizontal for about 100' then pointing the nose up about 80 degrees and disappearing near the speed of sound! I still have your Mustang SWR video and watch it occasionally just to get the juices flowing.
