TDC crosshair too sensitive for buttons

I have to bind my TDC control to my flight joystick main Axis, because my pov buttons are not Axis, when using the pov buttons or keyboard, even with TDC deadzone to 0, it still move way too fast, and almost impossible to select a target.

Try to adjust this: Options --> Special --> JF-17 --> MFCD Radar slew Rate
