here is a pic showing ply rib doublers and notches for landing gear plate support spars on w2 and w3. They are different than on my first one. on my first one I made a design mistake, in fact the landing gear plate was glued against the ply rib doublers and spars . on this one the plate will rest ON the rib doublers and ON the spars (it's more logic and more strong)
On my first one I corrected that mistake by putting big congere of epoxy/micro balloons on the joints. On this one the setup will be more straight.
