I forgot to put on my post about how I fly... I could see why you think I fly fast/hard etc. I never flew the ucd fast on that first plane. I was always too scared to do that. The only time I throttled up is if I was pointing straight up. I sealed the hinge gaps too.. so the flutter was not caused by that. All the hardware was 4-40 rods and nice upgraded hardware with no slop. I am positive that it was the servos and not the build, flying, etc. I did have a ys 1.10 that could blow a lot of wind over the surfaces like say when I pointed up, but, if they can't hold up to that then I say they are still not strong enough to do anything fun.

Now.. the ucd2 I would fly straight for short distances at full throttle. Would never yank it when I did that. I only seeled the bottom of the hinge gap on that one. I did all kinds of walls, waterfalls, and blenders and yanked it around pretty good.. had a blast doing it. Never had a problem with my mg servos. Those ds811's would not have lasted 1 month like I flew the ucd2.
