I purchased the 50cc Ultimate during the Black Friday sale. I assembled it with a DA 50. I took it to Florida for the FX3D where it did it's maiden flight. After about 6 flights the plywood root rib began to tear at the front attachement point. It was glued back together and flown again. After landing from the 8th flight my friend noticed that the bottom right wing was sagging. Upon disassembly we discovered that the wing tube socket is brocken away from the anchor point on the 3rd rib and the 2nd rib is broken where the tube socket goes thru it. I know the plane was inexpensive but I feel it should last more than 8 flights. These were not hard flights, not even a snap roll. I await your reply on a resolution to my problem.
Thank You
Chuck
