330X not holding altitude

[Kalpazan]

My 330X is otherwise stable to hover but it does not hold the altitude. It hovers 2 meters above the ground and in the next moment it will drop to just above the ground. Then it will jump up and then it happens all over again. It is like the throttle is too slow to react. I manage to hold ALT manually but it requires constant movement of the throttle stick which is boring. Is that how it is supposed to be or there is some problem ? I understand quads tend to respond more slowly than a heli but that much ?

It is stock configuration with 2200 2S brand new nano-tech lipo.

One solution is to consider a Naza Flight Controller to replace the stock one. The Naza features an auto-hold function for altitude that works great. You may also consider replacing your esc units.
