I'm fairly conservative and was going to use the kit-supplied plywood for fuse bulkheads in the wing area, and kit-supplied wood for wing spars/joiners. Since the plane will be fully glassed and flown in a scale-like manner (electric), should I keep the wing/fuse/tail surface sheeting the same thickness as in the kit and just replace the original with lighter wood, or can I go thinner?
In general, where are the real weight savings other than balsa vs. plywood?Does putting a medium amount of holes in ribs and things make that much of a difference?As you and tell, I always have just built kits according to the plans without too much modification (except for scale features).I generally keep a very close eye on weight, and for this project consider a 1-2 oz. weight savings per feature significant.In fact, I may take the aluminum-supplied cowls (over 2 oz. each) and try use them to make fiberglass molds.
