Hi GN. My plan for a taildragger conversion for my PT40 is much simpler (althoug a little more expensive). Buy aluminium MLG structure that bolts on to the bottom of the fuse. Epoxy in a ply doubler into the fuse for the screws to attach to. Only reason to move servo tray is for CG balance, but I am hoping I will be able to do that with a battery move only (don't want to fiddle around re-sizing a bunch of control rods).

Consider a landing gear like:
