uxcell Bullnose Propellers 5045 5x4.5 Inch CW CCW 2-Vane for RC Quadcopter Hexacopter Multirotor, Black 2 Sets

Product Overview

uxcell Bullnose Propellers 5045 are a set of two black propeller blades designed for use on RC quadcopters, hexacopters, and other multirotor aircraft. Each propeller measures 5 inches in diameter with a 4.5-inch blade length and features a bullnose tip design. The set includes blades that can be used in both clockwise (CW) and counter‑clockwise (CCW) flight configurations. Two blades are supplied per set, allowing for direct pairing on multirotor platforms that require opposing spin directions.

Dimensions and Construction

The specified dimensions are 5 inches for the overall diameter and 4.5 inches for the blade length. These measurements are standard for small multirotor drones that use 5x4.5 inch propeller sizes. The bullnose tip is a characteristic shape that provides a rounded blade tip, which is commonly used in hobbyist drone builds to reduce tip vortex noise and improve thrust efficiency at lower RPM ranges.

Design Features

Bulletnose Shape – The bullnose tip offers a smoother transition at the blade tip, which is a common design choice for hobby drones. This shape can aid in maintaining stable flight in light‑weight multirotor systems.

Two‑Vane Configuration – Each propeller blade in the set has two distinct vanes, a design that is typical for smaller propellers and provides a balance between lift and structural integrity. The two‑vane layout is compatible with a broad range of multirotor motor hubs that accommodate standard blade attachment.

CW/CCW Compatibility – The set includes blades that can be mounted for both CW and CCW rotations. This dual‑direction capability allows users to pair each blade with the appropriate motor on a quadcopter or hexacopter that uses alternating spin directions to balance thrust.

Application and Usage

These propellers are intended for integration with RC quadcopter, hexacopter, and multirotor systems. They are suitable for hobbyists who require a replacement or upgrade for existing 5x4.5 inch propeller slots. The black finish matches common drone motor housings and provides a neutral aesthetic for most builds. The dual‑set configuration allows a user to install blades directly without needing additional adapters.

Package Contents

• 2 Black Bullnose Propellers, 5x4.5 inches (CW/CCW)
• Compatible with standard 5x4.5 inch multirotor propeller mounts
• Ready for immediate installation on supported aircraft

Installation Guidance

When installing these propellers, ensure that the motor hub is clean and free of debris. Align the blade mounting points with the motor shaft, tighten the fasteners securely, and verify that the propeller is seated fully on the hub. For platforms that require alternating spin directions, mount one propeller on a CW motor and the other on a CCW motor. This arrangement maintains balanced thrust and reduces the risk of vibration during flight.

Maintenance and Care

After initial use, inspect each blade for signs of wear or damage. A damaged tip can affect flight stability, so replace any blade that shows cracks or significant wear. Store the blades in a dry environment to prevent moisture buildup, and keep them away from sharp objects that could nick the blade edges. Regular inspection is recommended to keep flight performance consistent.

Conclusion

The uxcell Bullnose Propellers 5045 offer a reliable 5x4.5 inch solution for hobbyists working with quadcopter, hexacopter, and multirotor aircraft. With a black finish, dual‑vane construction, and compatibility for both CW and CCW rotations, this set supports the standard needs of small drone builders.
