I oened up the the wings and installed mounts for the struts I built and anchored to the factory landing gear holes. Moved the gear forward(tail dragger now) and built a single set of wires on the tail feathers. Put in a Saito 72,which pulled the fire wall loose and required a little beefing up, and now we give it anything you can think of and it hasn't failed yet. A lot of fun to fly.
