What is “Emulate USB HID jostick”
When “Emulate USB HID joystick” is selected, the simulator part of the application will be deactivated and all control inputs will be sent to the USB joystick for use with third-party software.
No simulation information will be interpreted, dynamic functions such as autopilot or force change with airspeed are deactivated.
Trimming works, but will not be sent to the simulation.
Select Hardware Trim for enabling the Trim function
