   Manual Foldable Arm Hub
     This manual foldable arm hub is specially designed for light-payload, long-endurance UAVs. It supports 180° large-angle folding, enabling more compact storage and quicker deployment.
The main body is precision CNC machined from 6061 aviation-grade aluminum alloy and features a black anodized finish, delivering a refined texture, wear resistance and corrosion resistance.
Weighing only 40.1 grams, the lightweight design effectively reduces flight payload. It is compatible with 20mm-diameter UAV arms, locks firmly with no backlash, balancing portability and flight stability. It is an ideal component for light-payload, long-endurance multi-rotor Drones.
  
Cautions
During installation, ensure a secure connection between the arm and foldable hub. Apply moderate torque to screws to avoid thread stripping or breakage caused by over-tightening.
Do not use excessive force to pull, twist or bend laterally, as this may damage the internal structure.
Always inspect the locking status of the foldable hub before flight. Do not take off until no looseness or gap is confirmed.
After prolonged use, regularly check for wear on the springs and buckles. Replace any worn or abnormal parts promptly to ensure flight safety.
This product is intended for light-payload, long-endurance UAVs only. Do not use it for overloaded applications or high-load, high-vibration aircraft models.
