Its not moved directly by the joystick...
I'm using Keith's Portdrvr ( http://www.etherealsounds.com/ ) that retrieves all flight data needed and after some math they sended on the serial port, where a microcontroller translate them on servo positions. Be noticed that the refresh rate of Portdrvr is 45ms way too faster than
the 300ms that FSUIPC updates...
There in no real lag as way you think of. It does not use the real angle of the aircraft but calculates and sends forces. The lag you may notice on some cases are from the proportional servo code I'm using to protect the motors from breaking apart by doing some ramping on start-stop of the motion. But its okay and produces no motion sickness so far.
