Default RE: modeltech twister

Backwing - are you 100% sure that a hinge failure actually caused your very unfortunate loss? It could be, of course. However, possibly you may have experienced flutter in that elevator half due to clevis/horn problems, or other linkage or servo issues. Flutter tends to tear apart CA hinges very quickly, and when you land (or crash), all you see are torn or pulled out CA hinges.

With a 13x6 APC on my YS63 powered Twister, flat line speed is much greater than I anticipated. It's a fairly slippery shape. With those large elevator surfaces, you need a fair bit of servo power if you pick up some speed, in order to avoid flutter. I will re-prop this plane for more vertical performance. As a precaution, I replaced much of the hardware, notably the clevises, with something that was more secure than that provided. I do this fairly often with ARF's when the hardware is not as good as I feel it needs to be.

Best of luck with your next one!! Best precision flying plane in my fleet (including much larger aircraft), and does wonderful point rolls with little or no correction in roll. My CG is at 4-5/8" at the moment (range 4" to 5.5"). I will be gradually working it rearward to improve 3D. Hopefully it will maintain its wonderful precision.
