I converted a Senior and only put the axle even with the leading edge of the wing. I used a fiberglass DuBro LG and with the axle there it put my big 4" tire half way in front of the wing. It works perfect. It also tracks well and takeoffs and landings are easy. Make sure you use a good piece of ply or hardwood to reinforce the landing gear. I used 1/4" x 4" Ply the width of the fuse.
