Overview
| The optional GMC 305 control panel is a dedicated interface unit that provides advanced autopilot modes like indicated airspeed hold, independent flight director, and third axis yaw damper (when installed with appropriate servos). A control wheel integrated into the GMC 305 makes for easier pitch, vertical speed and airspeed adjustments. Plus, for added safety, the panel’s advanced LVL mode button commands the autopilot to help restore your aircraft to straight-and-level flight. And because the servos interface directly with the ADAHRS, the GMC 305 allows for standalone operation of the autopilot in the unlikely event of a display loss. Installation of the system is simple and straightforward, with industry-standard servo mounting kits available — as well as airframe-specific versions for the popular Van’s RV series (RV-4/6/7/8/9/10 models). |

Reviews
The unit was installed in an experimental CZAW SportCruiser and is working even better than expected. The Autopilot coupled to the G5 without requiring the GAD29b. We were pleasantly surprised that it also coupled with the 9 year old Garmin 496 that was already installed. I did not expect it to track a course from this unit but it does. We will return the GAD29b that was not required.
