Fibre Glassing a Kit
I want to fibre glass my next kit build (probably an RV-4) and have a question about the initial build.
The lightening holes in the fuselage have to be filled but what's the best way? Do I simply leave the lite ply in place and wick some CA into the seam, or is it better to replace the lite ply with sheet balsa inserts? Would the weight saving be worth the effort?
