I have a Ultra Stick 40 mod for ya, my stepson has one and he well lawn darted it slightly, and in the repair process we flipped it over and made a low wing stick. Very easy to do especially if ya are still in the assembly stage. Since he popped the V stab off anyway we just mounted it on the bottom (as well as the control rods), swapped places with the tailwheel. Then relocated the main landing gear to the top of the fuse in the same location just on the top. Left the wing in its original location no need to change a thing it thinks it is flying inverted. Color scheme was a little weird since we had flown it previously in the right side up configuration. The only thing that needs attention is the Rudder is less effective now, but no big deal just extend the bottom portion to match the now bottom of the fuse. It is a scream to see this thing.
I would advocate the firewall reinforcement, mount change, landing gear beefup, and better wheel. All in all a fun bird.
