1147 Propeller 11-inch مروحة درون

The 1147 Propeller 11-inch مروحة درون is a replacement rotor blade designed for use on compatible multirotor aircraft and hobby drones. Its 11-inch diameter provides a balance between lift and efficiency, making it suitable for applications where stable ascent, responsive throttle control, and predictable handling are required. The propeller is intended for users who need a reliable spare or a direct replacement for worn or damaged blades.

Installed correctly, this propeller contributes to smoother motor load distribution and can help reduce vibration when paired with properly matched motor and ESC combinations. The blade geometry is engineered to generate consistent thrust across a typical RPM range while maintaining predictable control response in hover and during maneuvering. Users should inspect mounting hardware and hub interfaces for wear and ensure the propeller is secured to the motor shaft according to manufacturer torque recommendations to avoid imbalance or loosening in flight.

Prior to each flight, visually check the blade for cracks, chips, delamination, or deformation, and replace the propeller immediately if any damage is detected. Do not attempt to repair compromised blades. Always verify compatibility with your aircraft's motor shaft diameter, rotation direction, and recommended propeller size before installation. Follow all safety guidelines when handling and installing propellers, and keep clear of rotating blades during testing and operation.
