It says, "plan by J. T. H." Of course, JTH may have only been the draftsman, not the designer.
The top and bottom shells alone weight 7.5 ounces and the metal cowl is another 1.4. It only has 184 square inches of wing area, of which quite a bit is in the fuselage. I'll try to hollow all I can, but it's won't be a stunter.
It's interesting that the plans omit the bellcrank, but show the leadouts. This implies that came out during the Jim Walker patent war.
As the third picture shows, I've added a crutch so I have something stronger that balsa to connect the engine, tank, bellcrank, landing gear, and top hold-down.
The kit gave me a nice airfoil leading edge, but the TE is just a rectangle, which leaves me with a big sanding project.
