Don't worry too much about getting that area covered too heavily. The entire forward fuselage inside on all my airplanes get a thin coat of polyurethane or epoxy surfacing resin and from what I've seen of this airplane, that's absolutely sufficient. The aluminum gear is really not rigid enough to beat any stress into the fuselage. And the gear is also about twice as large where it mates to the fuselage bottom compared to most. Heck, it might be 3 or 4 times the area of most.

I've considered that if I needed to build another, that one's aluminum plate gear would either be retrofitted or........ It might get a single piano wire gear that mates flat against it and doubles it. It's actually almost stiff enough on it's own. If aluminum could be retempered, I would have already done just that.

About the only thing close to being "wrong" with this gear is that it's just too short for what a bunch of people seemed to automatically wish to do, plug in a lot stronger engine.
