BETAFPV 16pcs Gemfan 45mm 3-Blade Propeller 1.5mm Shaft for 1S FPV Drone | Compatible with 1102 Brushless Motors for 1S Whoop Drone Quadcopter such as Meteor75 Pro 1S Racing
Product Description
Overview
BETAFPV offers a set of 16 Gemfan 45‑mm propellers, each with a 3‑blade design and a 1.5‑mm shaft. These components are engineered for use with 1S FPV drones. The propellers are intended to fit 1102 brushless motors, a common motor size for 1S whoop‑style quadcopters. An example of a compatible drone is the Meteor75 Pro 1S Racing, which utilizes the 1102 motor configuration.
Product Composition
- Set contains 16 individual propellers.
- Each propeller measures 45 mm in diameter.
- Design features three blades for balanced airflow.
- Shaft diameter is 1.5 mm to match standard 1102 motor hubs.
Compatibility Details
The 1.5‑mm shaft size ensures that the propellers engage securely with the motor shaft on 1102 brushless units. Because the motors are typically mounted on a 1S whoop‑style quadcopter, the propeller set is appropriate for models that use this motor and motor mounting geometry. The Meteor75 Pro 1S Racing is cited as an example of a drone that can utilize this propeller configuration.
Installation Guidance
When mounting the propellers, align the 1.5‑mm shaft with the corresponding motor hub. Tighten the propeller screws to secure each blade firmly in place. It is recommended to verify the correct orientation of the propellers before powering the drone, ensuring the blades rotate in the intended direction for the motor setup.
Performance Context
The 3‑blade design of these propellers is a standard choice for small, lightweight FPV drones. The 45‑mm diameter is a common size for 1S configurations, providing sufficient thrust while maintaining manageable weight. The compatibility with 1102 motors supports a range of 1S quadcopter builds, allowing pilots to use a single propeller set across multiple vehicles that share the same motor specification.
Maintenance and Longevity
Propellers should be inspected periodically for cracks or deformation, especially after a hard landing or collision. If a blade shows signs of damage, replace it promptly with a fresh component from the same 16‑piece set. Storing the propellers in a dry environment helps prevent moisture buildup, which can affect performance over time.
Typical Use Cases
These propellers are designed for recreational FPV flight where the drone operates on a 1S battery system. They are suitable for hobbyists who build or maintain drones that use 1102 brushless motors. The 16‑piece assortment allows users to swap out propellers as needed for different flight conditions or to replace worn units without purchasing additional components.
Purchase Information
Each unit is sold as a complete set of 16 propellers, providing a convenient supply for small‑drones enthusiasts. The set is packaged to preserve the integrity of each blade during shipping and handling. Buyers receive the full range of blades in a single shipment.
