Performance Proven in Extreme Applications

The unique high dynamic algorithm flight controller, which combines Kalman filtering technology and inertial navigation algorithm, is widely used in high-speed autonomous drones, such as the documentary “Amazing Drone Race China” shot by Tencent in 2018, the movie “WU KONG” shoot by mobile phone Huawei P30 Pro in 2019 and the XPENG T1 prototype Flying car. In 2021, the control system designed for agricultural vehicles can execute programmed missions automatically and has achieved the ideal operational effect, solving the industry problem of agricultural vehicles pressing seedlings when changing lines.

Autonomous Flight

Supports auto-path planning for search and rescue, material delivery, crop spraying; features one-touch return on signal loss or low voltage.

Instant Braking & Hover

A proprietary high-dynamic algorithm enables an instant stop at 180km/h in position-hold mode, delivering professional racing-grade handling for high-speed cinematography.

GeoFence

Geofence settings according to the drone management regulations promulgated by the country. It can fly within the prescribed flight airspace and fly law-abidingly.

Battery Monitoring

Integrated battery monitoring enables real-time voltage of the aircraft tracking via FPV goggles, FPV screens, or Mission Planner, ensuring safe return with sufficient power reserve.

Log Analytics

Multi-dimensional visualization with full-chain data traceability for flight optimization.

OSD Module Integrated

The pilot can intuitively grasp the status and coordinates of the aircraft at any time during the first-view (FPV) flight of aircraft such as racing drones and long-distance fixed-wing aircraft.

Proprietary High-Dynamic Algorithm

22 years of industry accumulation, 10 years of research in the field of flight control systems, continuous independent research and development capabilities, developed by the same technical team behind the eVTOL Flying Car control system. Through algorithmic optimization, domestic sensors achieve comparable or superior performance to imported alternatives, ensuring stable supply while maintaining product excellence, redefining core UAV supply chains.

Universal Airframe Compatibility

Effortless Mastery for Any Craft

Adaptable to diverse platforms including VTOLs, 3-8 axis multirotors, helicopters, UAV logistics systems, unmanned delivery vehicles, baitboats, underwater robots, aerial swarms, surveying drones, agricultural sprayers, firefighting drones, water quality monitors, forest patrol UAVs, epidemic-control robots, firefighting robots, and youth training platforms (e.g., UAV vocational competitions).

Compatible with SBUS/PPM/CRSF signal protocols

10 PWM output channels supporting multi-craft configurations

Software Vibration Suppression

Optimal Positioning in Complex Flight Conditions

Featuring the same software vibration suppression algorithm as Mini Pix, this technology effectively filters high-frequency vibrations to ensure sensor data accuracy and superior damping performance. Delivers precise altitude hold and position lock even during high-speed aerobatic maneuvers. For helicopters equipped with CrossFlight-CE flight controller, it maintains exceptional tail-holding precision and stable flight, without requiring physical damping mounts.
