here's what I did to beef up the gear area after the lower sheeting was in place I installed some light ply sheer webbing,I went with the century jet units and had to lower them into the wing per instructions.

if you look closely I also installed blind nuts so I could use allen head cap screws instead of the standard wood screws it helps when pulling the gear in and out and I can get them nice and tight, I also managed to fit the 3 3/4 wheels in there as well
