K3APro flight controller is specially designed for agricultural sprayer drones. It has a variety of modes and exclusive functions for agriculture sprayer drones. It supports manual, semi-autonomous and autonomous flight. It can monitor pesticide flow in real time and intelligently match the spray volume to achieve precise spraying . Equipped with professional ground control station, it is efficient and easy to operate.

Diverse Operating Mode for a Variety of Operating Environments.

K3APro built-in attitude-stabilization/height mode, GPS-speed mode and other control modes, easy to operate, flexible switching, free to change operating modes according to different operating environments, to meet the needs of agriculture spraying requirements.

Stable and Reliable Performance

K3APro is a new upgraded version of K3-A, the best-selling king of flight controller in the last three years. The reliability and stability of K3APro have been further improved and optimized on the basis of the original K3-A flight controller. From 2017 to 2018, K3A was used and recognized by 70% of domestic plant protection manufacturers, covering plant protection drone users in Asia, America, Europe, Oceania and other countries around the world.
Excellent Fixed Height Mode
Straight Route
More than tens of thousands of Shipment
Wide range of use
Perfect Stability

Equipped with exclusive agricultural App, precise and convenient control.

Personalized app tailored for agricultural sprayer drones, it can provide arbitrary polygon route for unregulated terrain, autonomous operation and improve work efficiency. It has a route memory function and can calculate the spray area, which helps the operator to grasp the dosage more accurately.

With the ABT feature, spraying work more efficiently.

Set the line and angle of A and B points through the remote, and the pesticides will be sprayed in a straight line, which is efficient and convenient.

Standard dual GNSS module, more safety of flight.

Dual GNSS magnetic compass configuration realizes greater redundancy of heading positioning control and ensures safe, stable and reliable flight.
