I have been facinated with this thread ever since I got my UDC 46 two weeks ago. Unfortunately, I followed some advice without understanding the consequences. I was worried about the weak landing gear so I added two wood screws to strengthen the fuse landing gear area and poured epoxy into the area above the landing gear bolts . Nice and strong. Flew without any problems, but while taxing back to the flight line we saw the right wheel hit some type of hole or bump in the ground and the fuse snapped in half at the narrowest part behind the fuel tank. But the landing gear is great ! Its on the bench now waiting for the epoxy to dry. I added some balsa reinforements to all three corners on the fuse wall behind the fuel tank. Lets hope this holds.
