A few things I ran into. The stock plastic pieces that thread onto the control horn bolts were a problem. The holes were to big. They are long enough I was able to cut off the factory hole and re-drill them.
The top center rib that stays on the cabanes. Is hard to get straight. After you bolt it up. Lay a yard stick on it and adjust it until the yard stick centers with the fin. The holes in the interplane struts are in the wrong place. I had to slot them to get them in without twisting the wings. The holes in the metal pins that go through the ailes are to big. The clevises and the rods for the top ailes will have a lot of play. That's all I can think of for now. I have mine sold. The 1.25 is to week to hover it. I would put a 1.50 or 1.80 on it if I was doing it again.
