For a heavy-lift multirotor UAV, the propeller is not a consumable accessory. It is a structural and aerodynamic part of the flight system. When a drone carries cargo, LiDAR, thermal cameras, agricultural equipment, industrial tools, or large battery packs, the propellers must produce stable lift while coping with high torque, long hover periods, and repeated load changes.

This is where glass fiber nylon has become a practical material choice for large UAV propellers. It combines the molding consistency of nylon with added stiffness from glass fiber reinforcement. For industrial drone manufacturers and operators, that balance matters because blade deformation, vibration, and hub movement can all affect flight stability and maintenance requirements.

GEMFAN HOBBY applies this material approach to its large-scale heavy-lift tri-blade propeller range, including the [Gemfan 20X10X3 Heavy Lift Propeller](https://www.gemfanhobby.com/20x10x3-glass-fiber-nylon-3-blade-cwccw.html) and the [Gemfan 22X10X3 Glass Fiber Nylon Tri-Blade Propeller](https://www.gemfanhobby.com/22x10x3-glass-fiber-nylon-3-blade.html). Both are designed for professional multirotor platforms, but they serve different aircraft sizes, motor systems, and payload targets.

@Archer Am a bit confused about this post. Is this supposed to be a company update? Or like an ad?
