51-Inch Propeller Double Compatible Hole Position Toothpick Machine Rack PC Propeller Set for Multi-Rotor Drones

This propeller set is designed for toothpick-style drone frames and multi-rotor builds, offering a practical solution for pilots who need reliable thrust and straightforward mounting. The double hole position allows compatibility with standard T-mount setups, making installation simpler on compatible motor shafts. With a 2.5-inch pitch and 129.4mm disc diameter, these blades provide a balanced thrust profile suited to lightweight racing or freestyle quadcopters. The set includes both clockwise (CW) and counter-clockwise (CCW) propellers, so you have a full matching set for quadcopter configurations right out of the package. Each blade is constructed from PC (polycarbonate), chosen for its combination of rigidity and impact resistance during normal flight operations.

Features and Construction

This propeller set focuses on practical design elements that support reliable flight performance. The key specifications are derived from the source dimensions and material details, ensuring every claim is grounded in what is provided.

Material and Build

The blades are made from PC (polycarbonate), a material that offers good impact resistance while keeping weight low for efficient flight. Each blade has a 5.5mm centre thickness and a maximum prop width of 12.69mm, providing a solid cross-section for handling normal multi-rotor thrust loads. The double hole position design accommodates T-mount holes of 1.5mm or 5mm inner diameter, depending on the chosen variant.

Size and Practical Fit

With a 129.4mm disc diameter and 2.5-inch pitch, these propellers are sized for 51-inch class frames and toothpick-style racks. The centre hole options (1.5mm or 2mm in the available colour choices) ensure a snug fit on compatible motor shafts. Colour variants include Half Green, Lake Blue, Lemon Yellow, Rose, Transparent Blue, and Transparent Gray, available in both 1.5mm and 2mm centre hole sizes.

Uses and Placement

These propellers are intended for multi-rotor drone applications, particularly on toothpick-style frames and other lightweight builds. The set configuration supports standard quadcopter layouts.

Event or Professional Use

For drone racing or freestyle events, the consistent pitch and diameter help maintain predictable handling during manoeuvres. The PC material offers a practical trade-off between durability and performance for competitive use.

Everyday Home Use

Hobbyists building or upgrading toothpick-style quadcopters will find these propellers straightforward to install on compatible T-mount motors. The included CW and CCW pairs simplify replacement of worn or damaged blades on a standard quadcopter setup.

Benefits and Buying Value

This propeller set offers practical advantages for drone pilots looking for compatible, ready-to-install blades for toothpick frames. The value lies in the double hole compatibility and the paired CW/CCW set.

Reuse and Low Maintenance

PC blades are generally resilient to minor impacts, reducing the frequency of replacements during typical flight sessions. The double hole design means they fit multiple T-mount shaft sizes, so you can use them on different motors without additional adapters.

Why Choose This Product

If you need a set of four propellers with matching rotation directions for a standard quadcopter, this set provides exactly that. The 2.5in pitch and 129.4mm diameter offer a known thrust profile, while the PC material gives a good balance of weight and impact resistance for toothpick-style builds.
