Go to the PID Tuning tab and then to the middle tab, Rate Profile Settings. By default, the rate type is set to Actual. I prefer using Betaflight Rates. Basically, the different types work the same way; only the variable names change. If you want to try another rate type, just experiment and see how each setting affects the curve.

The RC Rate determines the linear slope of the rate curve. A higher stick input will be translated 1:1 into drone movement. The downside is that with a high RC Rate, even small stick movements produce strong drone responses.
To gain finer control at small stick inputs, you can increase the Rate value. This turns the linear curve into a more exponential one: flatter at small stick inputs and steeper at higher inputs.
If that’s still too sensitive, the RC Expo can flatten the curve further at low stick inputs.
In the diagram, you can see how each variable changes the curve. The values at the end of the curves show the angular rate the drone will achieve for a full-stick input over one second. In the example shown, the drone would rotate 667° per second.
