The 6x3 Folding Carbon Propeller Set is a practical propeller option for small and lightweight electric RC aircraft. Its folding design allows the blades to fold back during landing, helping reduce the risk of propeller damage and making the aircraft easier to transport.
We tested this propeller on the Craycle Soar Stick, and it is one of the recommended propeller options for Soar Stick builders. It may also be suitable for other RC aircraft, but compatibility should always be checked according to the motor, battery, ESC, aircraft weight, and overall setup.
This propeller set is also compatible with the Craycle 3D printed folding spinner adapter. Since the adapter is a 3D printed part, print quality, filament strength, and assembly safety are very important.

Compatibility Note
This propeller has been tested on the Craycle Soar Stick and can be used with the Craycle folding spinner adapter. For other models, please check motor KV, battery voltage, ESC capacity, aircraft weight, and propeller clearance before use.
Safety Warning
When using a 3D printed spinner adapter, always inspect the print quality carefully. Poor layer adhesion, printing defects, weak filament, or incorrect assembly may cause the adapter to fail and the propeller to detach during operation.
The adapter can be printed with PETG. For higher strength, ABS or ASA may also be used. However, the filament must be high quality, the printer must be well calibrated, and the printed part must be inspected before every use.
Before running the motor, check that all screws are properly tightened, the blades can fold and open freely, and the adapter has no cracks or visible defects. Always test the propeller from a safe distance.
