Lower framerates can excite this kind of behavior with the multirotor flight controller. It's not normally an issue. But the Tempest 250 is tuned much closer to the edge than other vehicles in order to attain higher levels of performance in acro mode. As a result, it will get twitchy well before any of the other models do the same thing.
If you take steps to increase your framerate (try things like flying at a less demanding airport and/or turning down graphics quality settings) you should be able to eliminate the issue you're seeing and experience the intended behavior.
