B02Propellers

Accelerate air to produce thrust.

Manufacturers & products

Propellers are matched rotating pairs, with diameter, pitch, blade count and hub geometry defining a specific motor load. The blueprint uses nominal 127 mm props; commercial five-inch-class products can be larger.

American sourcing options appear first. A U.S. company or distributor label does not establish U.S. manufacturing. The origin notes identify the specific evidence and any limits.

manufacturer

APC Propellers

BD5.1x5.0E-3-B4

Three-blade FPV propeller bundle containing both rotation directions. [2][1]

U.S. manufacturing claim

APC explicitly states that its model-aircraft propellers are manufactured in USA. The referenced FPV product belongs to that range; upstream resin origin is not established. [2][1]

Program / application

Five-inch-class candidate; 5.1-inch clearance required [2][1]

Published manufacturing site: United States

Online catalog / ordering

Public product catalog; confirm the selected variant and current fulfillment directly. No stock or delivery promise is made.

manufacturer

Gemfan

Hurricane 51466 V2

Polycarbonate three-blade propeller with published geometry and mass. [3]

International supplier

Gemfan identifies a Ningbo, Zhejiang office. The product page does not identify its manufacturing plant or material origin. [3]

Program / application

Five-inch-class candidate; 131.8 mm clearance required [3]

Company location: Ningbo, Zhejiang, China

Manufacturer inquiry

Manufacturer product page provides contact details; use those or a verified retailer for the exact variant.

What remains unverified

The source set includes one explicitly U.S.-manufactured brand and one non-U.S. manufacturer; a third vendor was not added merely to fill a quota.

Where it comes from

A company address is shown separately from a published factory location. Request the manufacturing site and lot traceability for the exact part when sourcing.

What to compare

Actual diameter
Use the measured/published swept diameter when checking adjacent props and frame clearance.
Pitch definition
Product names can differ from the stated aerodynamic pitch; use the specification table.
Blade count
Additional blades change load, inertia and response, not only appearance.
Hub interface
Match bore, thread clearance, hub thickness and fastening arrangement.
Rotation pair
A quad requires the correct opposing rotation variants, not four identical handed parts.
Material
Compare stiffness, impact behavior and documented material rather than appearance.
Motor operating point
Compare thrust and current using the intended motor winding and voltage.
Mass and RPM limit
Mass influences rotational inertia; confirm applicable manufacturer speed limits.

Selection & integration notes

APC’s listed example is 5.1 inches; Gemfan publishes 131.8 mm for its five-inch-class example. Neither should be treated as exactly 127 mm.
No thrust or flight-time estimate is inferred from pitch and diameter alone.
