RAYI is a carbon fiber propeller manufacturer producing fixed (non-folding) multirotor propellers from 12" up to 72" in diameter, purpose-built for platforms ranging from standard industrial quadcopters to heavy-lift cargo and eVTOL drones. Every blade is molded in-house from 3K carbon fiber with a PMI aviation-grade foam or resin core, giving each pair the structural safety margin required for continuous commercial operation — not a hobby-grade part relabeled for industrial use.
If your team is sourcing a carbon fiber propeller manufacturer capable of producing at scale rather than a reseller quoting from someone else's catalog, this line is built specifically for that requirement: in-house molding, matched CW/CCW pairs, and documented thrust data at every size step.

Sourcing carbon fiber propellers for a commercial drone program is not a catalog purchase — it's a load-matching exercise. A carbon fiber propeller manufacturer needs to prove three things before a buyer commits: material integrity at scale, dimensional consistency pair-to-pair, and compatibility with the motor stack already selected for the airframe.
In-house molding, not outsourced pressing. Blades are laid up from 3K carbon fiber over a PMI aviation foam core, giving roughly twice the safety factor of standard hobby-grade construction — critical for continuous-duty agricultural, mapping, and cargo platforms.
Matched CW/CCW pairs as standard. Every order ships with correctly balanced Clockwise and Counter-Clockwise blades so multirotor thrust stays symmetric — a detail buyers frequently get wrong when sourcing from mixed suppliers.
Motor-stack compatibility documented. Sizing is cross-checked against mainstream industrial motor brands (Hobbywing, T-motor, MAD-compatible mounts) so procurement teams don't discover a mismatch after the blades arrive.
Heavy-lift range covered end to end. As a heavy lift drone propeller manufacturer, our range spans standard 12"–24" multirotor sizes up through 60"–72" oversize blades used on cargo and eVTOL platforms rated above 100kg thrust.
OEM/ODM and bulk production ready. Custom pitch, custom hub bore, private-label packaging, and volume production for teams scaling from prototype to fleet deployment.
This is the difference between a carbon fiber propeller manufacturer and a trading company reselling generic stock: we can tell you why a 64x20 clears a 130kg thrust envelope at ≤2900 RPM, and back it with tested data — not just a price sheet.
For multirotor industrial and heavy-lift platforms, propeller diameter is dictated primarily by target thrust and airframe class, while pitch is tuned for the balance between climb rate and hover efficiency your mission requires.
Standard industrial multirotor (12"–24"): Mapping, inspection, and light payload drones typically run in this range, prioritizing hover efficiency and flight-time-per-charge over raw thrust.
Mid-duty agricultural and payload drones (26"–40"): Spraying, spreading, and multi-kilogram payload platforms need higher static thrust at moderate RPM to sustain lift under load throughout the mission.
Heavy-lift and cargo-class drones (52"–72"): eVTOL, cargo delivery, and heavy industrial platforms operate at thrust envelopes from roughly 30kg up to 130kg+ per propeller pair, requiring the oversize diameters and reinforced hub structures found in our largest series.
| Payload Class | Typical Diameter | Thrust Envelope |
| Standard multirotor | 12"–24" | Light payload / mapping |
| Agricultural / mid payload | 26"–40" | Spraying, multi-kg payload |
| Heavy-lift / cargo / eVTOL | 52"–72" | Up to 130kg+ thrust |
If you already have a target diameter x pitch from your motor manufacturer's datasheet or from an existing supplier's part number, jump straight to that spec in the table below — most procurement teams reach this page already knowing the exact size they need.
Browse by exact diameter x pitch. Heavy-lift sizes below (52"–72") are industry-standard reference dimensions widely used across cargo and eVTOL platforms; RAYI produces matched equivalents in-house rather than outsourcing these larger molds.
What makes RAYI a carbon fiber propeller manufacturer rather than a reseller?
Blades are molded in-house from 3K carbon fiber with a PMI aviation foam or resin core, with dimensional and balance checks performed before shipment. As a carbon fiber propeller manufacturer, we control the layup process directly, which is what allows consistent thrust and structural performance across full production batches rather than single-sample quality.
Can you produce heavy-lift propellers larger than what's shown, such as custom diameters between 20 and 72 inches?
Yes. Our OEM program supports custom diameter, pitch, and hub bore specifications outside the standard catalog, including prototype runs for teams validating a new heavy-lift or cargo airframe before committing to full production volume.
Are your carbon fiber propellers compatible with Hobbywing, T-motor, or MAD-style mounts?
Hub and mounting dimensions are cross-checked against mainstream industrial motor brands during sizing. Send us your motor's shaft/mount specification and target thrust requirement, and our team will confirm compatibility or recommend an adjusted spec before you order.
Do propellers ship as matched CW/CCW pairs?
Yes, every multirotor order includes correctly matched Clockwise and Counter-Clockwise blades as standard, which is required for balanced thrust on any multirotor airframe.
