Dear friend, the X9 three-dimensional stage design features a seamlessly integrated motor and electric motor base, creating a lightweight structure that's a breeze to install and use. It's compatible with 40mm diameter circular carbon fiber tubes and can be utilized with 34.7, 3411, or 36190 blade options. An intelligent upgrade from the underlying system ensures a smoother power operation, enhancing the compatibility and matching of the flight control, thereby making the aircraft more stable and reliable overall. The four-axis plant protection multi-rotor aircraft, capable of handling 16kg or larger loads with FOC electric modulation, has been robustly upgraded for the diverse and challenging environments within the plant protection industry. The X9 power system now boasts overall protection and a closed motor design, safeguarding against the elements. The waterproof and corrosion-resistant plug-in design for the electric adjustable full potting protection and connector adds another layer of durability, with an impressive IPX6 overall protection level. The X9 system integration design seamlessly connects the electrical and mechanical bars and motor base, increasing the conduction heat dissipation area for higher power loads. The motor rotor's built-in centrifugal fan function ensures uniform and efficient heat dissipation, making the overall use even more reliable.
