After a quick review of the plans, 5 things caught my eye...

1. Seawind full-size uses a different airfoil (NASA NLF(1)-0215(F) )
2. Full-Size has wings at a 3 degree angle of incidence to the fuselage
3. The full-size has a critical tolerance that the wing incidence needs to equal the elevator incidence.
4. No drooping wingtip floats.
5. There aren't enough fuselage formers to accurately capture the shape of the seawind.

Has anyone modified the plans to more accurately represent the full-size Seawind? If so, how were the results?
