Excellent condition Stec 50 autopilot head, was working when removed. All buttons/lights work, new button membrane also. Autopilot head/computer was overhauled 06/2021 and was removed 09/2023 for an upgrade. Autopilot was configured to work with a G5 HSI heading source. It is currently setup for a TR182 but i believe it can be reprogrammed for any plane.
