My brother in law is working on the hot wire setup and has a good handle on that.
I have to come up with the Foam, an airfoil template and the setup for holding the foam...

I'm thinking of cutting the template out of oak and coating it with epoxy..
This ones a test so longevity of the template shouldnt be an issue?
Should I go with a flat bottom or symmetrical airfoil?
initial use will be for sscombat using .15 engines ( I've built a gnat with coroplast wings now I want to test the foam wings )
Down the road I want to make glider wings...

Looks like choice of foam is:
HD's pink Owens corning foamular - 2" x 2' x 8'
or
Lowes Blue Polyshield Styrofoam - 2" x 2' 8'

I plan on cutting a 2" x 2' x 1' block off the end of the 8 footer and use that as my wing blank. to cut a roughly 9" x 22" wing half ????

HAs anyone used these materials and is one better than the other?

thanks
