I ran 2000 on my R30 OS.32 because it the little R30 likes it, its happiest at a high head speed, more stable and the OS .32 can handle it, faster cyclic, best power etc. the reason the big guys doing 3D don't run above 1800 is because ther are running 90 sized helis, its not safe to be turning the blades as fast, parts wear out quicker, engine will bake and so on. The 30's are small and like a high head speed. I did not mean to be rude when I said your info was false sorry if you took it that way, what I ment was it is still safe to run it that high.
