Perhaps a better prospect for a flyable design (if not from the kit pieces and wood) would be the Ringmaster Imperial.
For once the Sterling kit plans had actual layout diagrams to build over, mostly. Much larger than the Super Ring' and a few oddball touches (Like the fuselage sides were not parallel, but slanted in at the tops...) However, plenty of wing area, big enough to carry, and benefit from, a modern .40 to .46 engine.
Still, an unflapped (if I recall correctly) Ringmaster planform and tail shapes beastie... Not a world champs challenger, but sure to be unusual. Someone should have kit plans, if we ask around. Intact kits on *bay? No idea, I don't play there; I have enough junk valued items already.
