Added the mains from a Senior Telemaster to my SST .40. It's a touch too wide at the fuse, but not much. Sig pants, 2 3/4" tires and a Klett tailwheel. Tip plates and a K&B .61. It's a real blast to fly, but I had to pay attention to the angle of those thick gear legs as relates to the wing, to avoid a lifting effect at speed, since the fuse bottom was tapering towards the nose, and the gear was canted slightly and needed a shim to level it with the wing. It flies with one click of down trim. I also needed to surface mount the elevator and rudder servos to balance it without adding weight.
