If you have a computer radio, try playing around with the throttle curve feature. Your throttle curve is probably linear at this point. That is, the throttle servo moves in a direct relation to the stick position.

By changing the throttle curve, you can lengthen the 'feel' of the powerband with your stick. In other words, when the throttle is in the powerband your throttle servo will not be moving a lot in relation to the stick.
