ZeroUAV YS-S4 Autopilot GPS Flight Control System (V3)

ZERO TECH continue to push the boundaries with the YS-S4 autopilot system. The V3 version has all new firmware, new attitude stabilization algorithm and optimized hardware structure, all in all the YS-S4 provides better all round flight performance than its predecessor.

The innovative mini all-in-one design simplifies the installation process and also saves space and weight. With its built-in inner damping, controllers, 3-axis gyroscope, 3-axis accelerometer and barometer, the YS-S4 V3 can measure flying altitude and attitude for autopilot / automatic control precisely. Its compact size makes it extremely simple to install to any multitotor frame.
