Current Price: 45.00 USD

I think most of you are like me, and not looking for a working rate gyro for your aircraft.  I collect interesting gyros and avionics.  This one is without its case, so you can see what is inside. 

It is a great collectable, and will make a nice display or a desk toy for that guy who has everything.

This Bendix-King KRG 331 Rate Gyro is an aircraft avionics component—specifically part of an autopilot / flight control system.

Its main job is part of what pilots call a yaw damper.

It was used to help an airplane stay stable and coordinated in flight, especially side-to-side.

The KRG-331 is a yaw rate gyro. That means it measures how fast the aircraft is rotating around its vertical axis (yaw—think nose swinging left or right).

-          It senses angular rate (turn rate) in yaw

-         Sends that data to the aircraft’s autopilot / flight computer

-         The system then makes small control corrections automatically
