Don't let the simple look of the EZI-NAV system fool you. It's a complete three-axis autopilot system. The EZI-NAV System is a fully integrated digital autopilot and ground station system that can be used to operate Unmanned Aerial Vehicles (UAV) with wingspans of 1 meter and up. There’s no calibration required and it weighs around pound. The EZI-NAV autopilot controls the vehicle's flight path using GPS technology and our exclusive auto rate-of-turn sensing software that takes the guesswork out of setting up the aircraft's control system. The system is available with the original IR horizon sensing attitude control for roll and pitch or our new IMU.
