The Triden series provides superior performance and reliability by using state of the art SMT digital electronics. The Triden uses both rate and position data to efficiently control the aircraft. The swift, smooth response of the Triden will take you through rough air without a hitch. Triden features the Expandable System Architecture (ESA), a concept CFS pioneered. ESA allows you to install an autopilot then add features as your needs change or a new features become available; all without replacing the autopilot.
