I am building Cassutt and because long storage time i don´t want to use original 1/8 mahogany ply for skin. That skin ply looks like it have too much humid at some time for storage. I live in Finland, so i can buy aircraft quality birch ply relative easy...just this is much heavier than mahogany.
How can i know, how much i can reduce thickness for birch skin. I can buy 2 mm or 2,5 mm here, but i prefer use thinner one (lighter plane) if i could. Is there any conversion table for this kind of problem?
Cassutt have 275-300 mph Vne... it is flutter tested for 400 mph (TAS)
