Together with the Saitek Yoke there is a throttle quadrant with a “PS2” connection to the yoke’s USB. Another type of this throttle quadrant listens to the article number PZ45 and is connected with an USB plug. Both work identical.
in some situations the power to the usb connected hardware is insufficient; just buy a PZ44EX Power Adapter – Saitek Pro Flight Yoke System HERE.
Insufficient power results in unpredictable disconnection of attached usb hardware which are connected to the yoke. Read the SPAD page how to connect your USB devices and how to control them.
