Plastic Propeller 2 Positive and 2 Reverse for Multiaxis Drones – 31mm PC Blades

This plastic propeller set offers a practical solution for multiaxis drone enthusiasts needing a balanced set of clockwise and counterclockwise rotating blades. The pack contains two positive and two reverse propellers, allowing you to replace worn or damaged blades on small quadcopters or tricopters without mixing types. Each blade measures 31mm in length with three fins, a pitch of 1, and is made from lightweight PC material weighing only 0.16g. With a propeller disc diameter of 4mm, plate thickness of 5mm, and a 1mm shaft, these components are designed to fit compact motor systems on aircraft under 30cm in size. Available in gray, light blue, and pink, they bring a subtle personalisation option to your build.

Features and Construction

These propellers are built for straightforward installation and reliable operation on small drones. The PC material keeps weight low, while the 31mm length and 3-blade design provide balanced thrust characteristics for basic flight needs.

Material and Build

Each propeller is made from polycarbonate, a plastic known for its good impact resistance and dimensional stability in thin sections. The blades have a smooth finish to reduce air resistance, and the central hub is moulded to fit a 1mm shaft securely. The propeller disc diameter is 4mm, and the paddle plate thickness is 5mm, ensuring a snug fit on compatible motor bells.

Size and Practical Fit

At 31mm (1.22 inches) length with a pitch of 1, these propellers are intended for very small RC aircraft, typically those with a frame size under 30cm. The 3-blade configuration helps produce a compact thrust pattern, making them suitable for indoor flyers, micro quadcopters, or lightweight test builds where space is limited.

Uses and Placement

This set is designed for multiaxis drone applications, particularly where a mix of clockwise and counterclockwise rotation is required. The 2 positive and 2 reverse configuration matches the most common quadcopter motor layout.

Event or Professional Use

For hobbyists running drone workshops, demonstration flights, or indoor racing events, these propellers provide a low-cost, easily replaceable option. The colour choices (gray, light blue, pink) make it simple to distinguish between different propellers during assembly or maintenance sessions.

Everyday Home Use

Home pilots flying small coaxial or quadcopter toys can use this set as a direct replacement part. The PC material withstands minor bumps and scrapes that occur during indoor flying, and the lightweight nature helps keep flight times reasonable on small batteries.

Benefits and Buying Value

This propeller set offers a balanced, ready-to-fit solution for owners of small multiaxis drones who need both rotation directions in one purchase. The pack includes four blades (2 positive, 2 reverse) for a complete swap, saving the hassle of sourcing individual units.

Reuse and Low Maintenance

Because the propellers are made from durable polycarbonate, they can be reused across multiple flights as long as they remain undamaged. Regular inspection and quick replacement when needed help keep the drone in flying condition without major disassembly.

Why Choose This Product

For users flying micro drones or building lightweight custom quadcopters, this set provides a reliable, lightweight, and colour-coded option. The specific 31mm length and 4mm disc diameter cater to a niche size class not always covered by generic propeller packs, ensuring a proper fit for compatible motor shafts.
