Not necessarily a weird heli... The blades on my K2 only start to center up above the 50% throttle. Anything below that and they are off. I have a cnc head on my K2 and I fought many hours trying to get the thing to track straight thru the throttle range which just isn't possible, or at least not with mine. So I gave up trying. As long as it tracks true in the 50% plus is all that matters, aything below doesn't affect me. Unless al I ever do is let it spin up on the floor and never lift off.. LOL

Happy fly'n
