Propellers and matched hubs
Geometry, direction and hub fit must be defined together. The rotor choice also belongs in the motor and ESC review.
What to specify
Use these fields to describe your requirement. Values are supplied by the buyer or the responsible integrator; this reference does not list an in-stock SKU or a universally compatible replacement.
| Requirement | Information to include |
|---|---|
| Geometry | Diameter, pitch and blade count |
| Rotation | CW/CCW and viewing convention |
| Mount | Bore, bolt pattern and hub |
| Construction | Fixed/folding and material |
| Limits | Manufacturer-documented speed limit |
| Pairing | Motor and aircraft reference |
Sample and acceptance review
Use the maker’s installation and operating-limit documents and preserve the exact propeller part number. Request a fit sample and condition inspection.
A common purchasing mistake
Two propellers with the same nominal diameter may differ in hub interface and operating limits.
Related purchasing decisions
Identify a propeller beyond diameter and pitch
Propeller procurement needs exact identity, rotation and mounting details. A familiar size label does not resolve the hub or the applicable operating limit.
