Hello,
I had stripped servos in boths of my wings ( they were nylon geared ). I was super-sure the geometry was right on with the manual.
Unfortunately, I had to bite the big one and buy another, which I almost am afraid to fly! I have only flown the new one once since I put it together. I was definatley not flying the model fast, or even very hard. My friend did though, and hes a great up-and -coming 3D pilot ( Chris Maier ) who did the Ultimate 3D DVD with the Extreme Flight Yak last year. If anything was going to break, it would have when he flew it!
I originally thought I didnt seal the hinge gaps, but I had. I re-measured the horns, and they were right on with the manual, so either it was the Dubro heavy arms with the ball links from H9, or a bad wing.....either way, I lost........
