Logitech G series X56 HOTAS system. a) Throttle used for about 6 to 8 months. Switch 5 does not work (switch 6 works) and hasn't worked from new (I only started using the throttle after my original throttle developed faults, but by this time the system was passed the guarantee period) b) Joystick base. New and unused (I attached the joystick grip to my previous base) c) Joystick grip. Has had about 18 months use, all parts working when I upgraded the joystick to a VKB). Additional springs as supplied with the unit are included in the box. I have enjoyed using the X-56 but decided to upgrade to VKB EVO and STECS standard.
