I’ve always been a fan of the Goodyear/Formula 1 Aircraft made during the Heyday of of the 50’-60’s-70’s.
I’m talking the Full sized versions, not the models. There are a bunch of Models that could be done by “Kit-bashing” any of these three (4) kits. John Sharp’s Nemesis Racer heads the list. As I recall, the Cosmic Wind racers were popular too, both the low wing, Little Toni, and its Mid-wing brother “the Minnow”.
I have often wondered why you couldn’t either re-cut the Fuse for a mid-wing version, or more simply, leave the center fuse cut-out (epoxied) and move the wing up ala Shoestring. Of course, you’d need to recut the Doublers to match. The real “Minnow” was actually a bit longer in the Nose and had a stretched fuse.
The purists would Poo-Poo the ideas here and the Sport Racers (Goldberg, Fox-Berg, MidWest Sport Race) are limited to kits (or faithful reproductions). I wonder how hard it would be to get Brodak’s or RSM to introduce a newer version of a different airplane, keeping with the spirit and intent of the original CG or RSM kits? A Cassutt could be done from a Buster kit (just re-cut the Tail feathers), similarly, build an Owl. The venerable “Rivets” could be attempted, I even sketched one out once. There are history books about these birds, it might be a fun and interesting experiment.
