Logitech FLIGHT THROTTLE QUADRAN Repair

The Flight Throttle Quadrant is a desktop flight-simulator control module designed for tactile, manual control of throttle, propeller and mixture (or multiple engine throttles) in flight-sim setups. It is built from durable materials — high-strength ABS plastic housing with metal lever arms and a steel mounting/bracket interface — for high-cycle mechanical durability in repeated use. Key features include three full-range analog levers, a stable weighted base with rubber feet, programmable switches on the base, and standard USB-HID connectivity for plug-and-play operation. Logitech's support notes that downloads and legacy software for some older devices are no longer maintained, so it uses standard OS HID drivers for basic functionality.

The Logitech FLIGHT THROTTLE QUADRAN can be identified by the model number (M/N JU0026). The model label is on the FLIGHT THROTTLE QUADRAN can be identified by its three-lever quadrant layout with Logitech/Saitek branding and a model/serial label on the underside of the base. Controls and user-accessible switches are on the top face of the unit; the USB cable exits the rear. This label lists the model (M/N), part (P/N), and serial (S/N) numbers.

Common repair-relevant faults include worn or noisy potentiometers causing axis jitter or dead zones, sticky or misaligned levers from dirt or worn bushings, and USB connectivity issues. Diagnose by verifying USB enumeration and axis movement in OS/Game controller properties, recalibrating in software, listening/feeling for mechanical binding, and testing potentiometers with a multimeter for smooth resistance change.
