Yeah, I agree with hilleja about glassing the landing gear block. When I built mine I laid a couple layers of 1/2 oz. cloth over the landing gear block on the bottom inside of the radio compartment and wrapped it up the sides about 1/2-3/4 of the way. Turned out great and have had no problems so far (knock on wood). I also wrapped a layer around the wing bolt down block and epoxied the hell out of that. It was split when I got it. Again, no problems there. Take it easy!
