This may be a common problem? This carrier based "AWACS" has folldable wings. The barely adequate instructions specify 50 gm weight in nose, but that is clearluy with wings extended. With wings folded, there's much more weight aft and suspect it will be a tail sitter.
I'd rather not assemble the whole plane with tape & rubber bands to answer this question, and getting the fuselage halves apart after gluing is a pain. Anyone have a hint to avoid guesstimate the correct amount of weight with folded wings, or do I just cut a hole in the nose after it's done?.
