The crude drawing below is as if you were looking inside the plane where the landing gear bolts come through the landing gear block. I had to completeley replace mine as it ripped out and snapped in half after a reletively light pancake landing. The red rectangles represent 1/4 inch balsa stock that I epoxied (do not use CA here) in place. I then used an epoxy brush and liberaly painted all the corners and joints being careful not to epoxy my landing gear bolts Hope this helps.
