Bandit, Schutt is using a X45 throttle and a CH Fighterstick.
You have to plug the X45 Throttle (serial) into the Stick and then the Stick USB into Computer. You need a second USB port on your Computer for the CH stick. Unfortunatly, youll have to keep the Saitek stick to route the signal through - cant plug the throttle directly into the computer.
Then, when programming in AH, select the CH Stick, and Map it. Then, when mapping the Saitek X45 Flight controller, just leave the X and Y axis and all stick buttons unmapped and just map the throttle axis/buttons. If you do not know which button is which in the list in AH, just click the button on the stick/throttle and it gets highlighted outomatically (double pressing the button will even open the MODIFY window).
Im not sure if or how programming with the respective Software (saitek/CH) would work, but id guess very much alike (ie just "ignore" the X45 Stick functions when mapping). Neither me nor Schutt ever installed any of it.
