Corgi servos are designed to electrically move control trim surfaces and other systems in homebuilt and other light aircraft applications. These servos can also be installed in any aircraft where electric trim control of a trim tab is desired. In modern homebuilt aircraft and LSA, they are commonly installed alongside complete avionics+autopilot systems such as those available from Dynon and Advanced Flight Systems. When integrated, they afford the pilot autopilot auto-trim capability, which reduces the need for pilots to trim the aircraft manually when under autopilot control.
