RE: Who makes scale Edo floats?
Well 1/5 what? He calls those 18% Beaver that close to 5th scale for that plane. I bet they'd look fine on that size Stearman
Shoot the guy an email, since it's CAD and laser cut, maybe he can cut a set slightly smaller for you,, you'd have to tinker with the pre made fiberglass parts or use wood for that area, but that wouldn't be to hard to modify.
good luck,
p.s.
Sig has a 46" set, but their not a scale as those
