GMC 305 Autopilot Controller

Adding the optional GMC 305 to your G3X autopilot gives you features normally reserved for high-end aircraft that utilize the GFC 700 digital autopilot system.  Functions include indicated airspeed hold, independent flight director, VNAV steering and for added safety, a dedicated level button that returns the aircraft to straight and level flight from unusual attitudes.  When installing a third servo, the GMC 305 will also add yaw damper capability to your system.
