RAYI supplies carbon fiber folding propellers from 12 to 72 inches for multirotor UAVs, agricultural drones, cargo drones and heavy-lift platforms.
Compared with a one-piece fixed propeller, the folding design allows large blades to occupy less space when the UAV is stored or transported. This becomes particularly useful as propeller diameter increases and the aircraft becomes more difficult to pack, ship and deploy in the field.
Standard sizes are available for existing propulsion systems, while custom diameter, pitch and hub configurations can be evaluated for new UAV projects.
| Selection Factor | Folding Propeller | Integrated Fixed Propeller |
|---|---|---|
| Storage footprint | More compact | Larger |
| Transportation | Better for large UAVs | Less convenient as diameter increases |
| Hub structure | Folding hub required | Simpler integrated mounting |
| Blade replacement | Individual blade replacement may be possible | Usually replace complete propeller |
| Structural complexity | Higher | Lower |
| Large UAV deployment | Strong advantage | Suitable where transport space is sufficient |
| Typical applications | Agriculture, cargo, heavy-lift UAV | General multirotor, industrial UAV |
| Selection priority | Folding mechanism + hub compatibility | Thrust + diameter + RPM |
If your main concern is payload and thrust matching rather than folding, use our Carbon Fiber Integrated Propeller range.
RAYI's folding range covers compact industrial UAVs through large heavy-lift multirotors.
Suitable for compact and medium-size multirotor platforms where folding blades help reduce storage and transport dimensions.
Typical applications include:
Industrial inspection drones
Mapping UAVs
Portable multirotor systems
Small commercial UAV platforms
This size range is commonly considered for larger propulsion systems where higher thrust requirements begin to make propeller diameter a significant transportation issue.
Typical platforms include:
Agricultural spraying drones
Spreading UAVs
Industrial payload drones
Medium cargo UAVs
Large-diameter folding drone propellers are particularly valuable when a heavy-lift aircraft needs large rotor discs but must still be transported efficiently between operating locations.
Typical applications include:
Heavy-lift multirotors
Cargo drones
Logistics UAVs
Large agricultural aircraft
Specialized industrial UAV platforms
For these systems, blade diameter, hub structure, motor torque, operating RPM and available folding clearance should be evaluated together.
A folding propeller is not automatically better than a fixed propeller. The main question is whether the aircraft benefits from the folding structure.
A carbon fiber folding propeller is usually the better choice when:
The UAV uses large-diameter propellers.
Transportation or storage space is limited.
Drone arms or propulsion modules are folded during transport.
The aircraft must be deployed frequently between operating sites.
Agricultural or industrial UAVs need more compact packaging.
The airframe has already been designed around a folding hub.
Individual blades need to be replaceable separately from the complete propeller assembly.
A fixed integrated propeller may be more suitable when compact storage is not required and structural simplicity is the main priority.
Different UAV projects may require different supply configurations.
Suitable when:
The existing hub is retained.
Only damaged or worn blades need replacement.
Blade root dimensions match an existing system.
The UAV manufacturer already has a validated hub design.
In this case, hub drawings and blade-root dimensions should be provided before ordering.
More suitable when:
A new UAV platform is being developed.
The existing hub cannot match the required blade.
Diameter or pitch is being changed significantly.
The propulsion system requires a new mounting interface.
For new designs, the motor, propeller and hub should be evaluated as one propulsion assembly rather than selecting each component independently.
RAYI supports standard and custom folding propeller projects for UAV manufacturers and propulsion-system developers.
Customization can include:
Propeller diameter
Pitch
Blade geometry
Blade root dimensions
Hub bore
Mounting interface
CW / CCW configuration
Surface finish
Weight optimization
OEM branding
Private-label packaging
If an existing catalog model already matches the motor and airframe, using a standard propeller can reduce development work.
For special motor, hub or aircraft requirements, see our Custom Propeller Solutions.
The main practical advantage is reduced storage and transportation space, especially on UAVs using larger propeller diameters.
RAYI's folding propeller range covers approximately 12" to 72", including options for compact multirotors, agricultural drones and heavy-lift UAVs.
It may be possible if the blade root, mounting holes, pin dimensions, thickness and folding geometry are compatible. Hub drawings or samples should be provided for confirmation.
Yes. Diameter, pitch, blade-root dimensions and mounting requirements can be evaluated according to the UAV and propulsion system.
Choose folding propellers when transportation, storage or folding-airframe integration is important. Choose integrated fixed propellers when structural simplicity is more important and the aircraft has sufficient storage and transport space.
