Using the Joystick does not allow the same rate of change using the full range of the joystick in comparison to keyboard inputs. Joystick is properly configured Cyclic (UDLR) and Rudder, XYZ amounts vary from -100 to +100 in the configurator. So far so good.
But the translated rate of change is by far nowhere near comparing X +100 with the keyboard "D" input.
This makes flying with the stick pretty much unusable with the stick, as you can't use the full range to steer the helicopter thus allows only for light direction changes.
