That's because it IS responsive, they are not near as stable as larger heli's, which is why they are the hardest to fly. The bell-hiller would make it even more responsive, if you can't control it now I don't reccomend that upgrade. I can tell you right now what the problem is, EXPERIENCE. Invest in a simulator such as Realflight G3, log some hours, then come back and you will be flying like you've done it for a while. You can crash as much as you want and you won't be losing money, it's an invaluable learning aid.
