Choosing the correct propeller is one of the most important factors affecting UAV performance.
Different propeller sizes provide different thrust, efficiency, payload capability, and flight characteristics.
The table below helps engineers and buyers quickly select the appropriate propeller for their UAV platform.
| Propeller Diameter | Typical Aircraft | Key Advantages | Recommended Applications |
|---|---|---|---|
| 12–18 Inch | Small Multirotor UAV | Lightweight, fast response | Inspection, security, mapping |
| 20–24 Inch | Commercial Drone | Balanced thrust and endurance | Surveying, photography, patrol |
| 26–32 Inch | Agricultural UAV | High lifting efficiency | Crop spraying, monitoring |
| 34–40 Inch | Heavy Lift Drone | Stable thrust output | Cargo transport, industrial inspection |
| 42–52 Inch | Large UAV | High payload capability | Logistics, emergency rescue |
| 54–72 Inch | VTOL & Special Aircraft | Maximum thrust | Heavy payload UAV, military, experimental aircraft |
Compared with conventional polymer propellers, carbon fiber propellers provide significant advantages for professional UAV applications.
Lower rotating mass improves acceleration and flight efficiency.
Maintains blade geometry under heavy aerodynamic loads.
Precision manufacturing reduces vibration during flight.
Carbon fiber resists fatigue better than conventional plastics.
Higher aerodynamic efficiency helps increase flight endurance.
As an experienced Carbon Fiber Propeller Manufacturer, RAYI supports complete customization services.
Available customization includes:
Diameter
Pitch
Blade quantity
Airfoil optimization
Carbon fiber weave
Hub structure
Mounting hole
CW / CCW rotation
Surface finish
Logo printing
Private label packaging
We support prototype development, low-volume production, and large-scale OEM manufacturing.
Selecting a propeller independently is not enough for professional UAV development.
RAYI also provides matching recommendations for:
Brushless Motors
ESC
Flight Controller
Power Kit
Battery System
Each carbon fiber propeller undergoes multiple inspections before shipment.
Quality procedures include:
Raw material inspection
Mold accuracy inspection
Weight inspection
Static balance test
Dynamic balance test
Surface quality inspection
Dimensional verification
Mounting hole inspection
Batch consistency verification
Final packaging inspection
These inspections help ensure stable performance for professional UAV operations.
Q: What is the difference between carbon fiber integrated propellers and carbon fiber folding propellers?
A: Integrated (fixed-hub) propellers form blades and hub as a single rigid composite structure — no mechanical pivots. Folding propellers use pivot joints to allow blades to fold flat. Fixed-hub designs provide better structural stiffness, more stable dynamic balance, and cleaner blade root aerodynamics. Folding designs offer transport and storage size reduction. For continuous high-thrust operation on platforms without transport constraints, fixed-hub is the recommended configuration. Browse RAYI's folding propeller series for fold-capable options.
Q: Can I use RAYI carbon fiber drone propellers with any motor brand?
A: Yes, with correct specification matching. RAYI propellers use standard hub bore sizes that are compatible with motors from T-MOTOR, MAD, Hobbywing, KDE, and all major industrial UAV motor manufacturers. Verify hub bore diameter, bolt circle diameter, and rotation direction with your motor specification before ordering. Contact RAYI engineering if you need confirmation for a specific motor model.
Q: What sizes are available, and what is the size selection process?
A: RAYI's fixed-hub carbon fiber catalog spans 12×4 to 72×31. Start with your motor's recommended propeller diameter range (usually specified in the motor datasheet at your target voltage), then select pitch based on your platform's speed-vs-efficiency trade-off. Contact RAYI with your motor model, S rating, and target operating point for a specific recommendation.
Q: Are all propellers balanced, or only certain sizes?
A: All RAYI carbon fiber drone propellers — every size, every unit — pass precision dynamic balance inspection before shipping. There are no exceptions for smaller sizes or standard production runs.
Q: Do you supply matched CW/CCW pairs?
A: Yes. All sizes are available as CW (clockwise) and CCW (counter-clockwise) matched pairs, produced in the same batch to minimize weight and geometry variance between the two rotation directions.
Q: What are the shipping options?
A: Sample orders ship via DHL, FedEx, or UPS international express (typical 5–10 business days). Bulk production orders ship by sea freight or air freight depending on volume and urgency. Contact RAYI for current freight quotes to your destination.
Q: Do you offer custom sizes not in the standard catalog?
A: Yes. RAYI manufactures custom diameter and pitch combinations, custom blade counts, and custom hub configurations for OEM customers. Minimum development quantities apply. Contact our engineering team with your technical specification to initiate a custom project.
