The fuselage adopts a low-front and high-rear design to reduce air resistance during flight and improve spraying efficiency.
The arm adopts an oblique folding design, which reduces the volume by 60% compared with the same capacity drone. The new model is more convenient to transport and store.
The folding part of the arm is upgraded to a one-button buckle, which greatly enhances the stability and makes it easier to operate.
The battery slider material of the new model has been upgraded to nylon carbon fiber, which is smoother and more stable than before, making it easy to replace.
The bottom of the medicine tank is integrated with water pump and flow meter. The waterproof joint is pre-installed, which is convenient for future maintenance and replacement.
The waterproof level of the distribution board reaches IPX7, and the connectors of spraying and spreading are detachable. It allows users to replace different operating devices at any time.
The new model is equipped with a smart distribution board and a tiled heat sink to make its heat dissipation more efficient. It supports fault detection and storage, accurately locates the cause of the fault, and integrates functions such as anti-ignition, power monitoring, data recording, and CAN communication.
