The Logitech G Flight Throttle Quadrant is a USB powered, 3 axis lever for PC flight simulation. The throttle quadrant enhances control for throttle, prop pitch and mixture and the three, two way toggle switches that allows programming for nine different commands including flaps, landing gear, spoiler and external and internal views. The throttle quadrant is fully functional and has been used only on MS Flight Simulator. It requires a Logitech Yoke for interface and power.
