Pro-Range 1447 (14x4.7) Glass Fiber Nylon Propeller 1CW+1CCW Pair - Gray

These propellers feature a 7.86mm bore and include plastic reducers (adapters) for 3mm, 4mm, 5mm, and 6mm motor shafts. They are designed for large, low-KV brushless motors commonly used on heavy-lift drones and industrial multirotors. Always ensure your motor's KV rating and power output are suitable for a 14-inch propeller load.

Pro-Range propellers are precision molded for consistent weight and geometry. However, for optimal performance on large, sensitive platforms, it is always recommended to perform a final dynamic balance check before flight. Imbalance can cause vibrations that affect flight controllers, camera gimbals, and overall frame durability.

Glass fiber reinforcement significantly increases the stiffness and tensile strength of the nylon base material. This results in a propeller that is more resistant to bending under high thrust loads and more durable upon impact compared to standard plastic props, while still maintaining a favorable weight for efficiency.
