Aluminium 3 blade prop

Hi community,

Sharing something I’ve been working on for a while. Pics below of my DIY aluminium 3 blade propeller.

The prop has been designed as a b-series and slightly tweeked to be able to be machined in my homemade 3 axis CNC machine. Blade area ratio and diameters are very similar to the FD and so far very pleased with it.

So far blades are aluminium and the hub is printed in PETG in my trusty prusa MK3. The hub I have at the moment is for the 6384 Aliexpress motor.

Few pics of the process.

The whole jouney has taken a bit but I’m quite pleased with the results.

Next I would love to have some more feedback on how these compare to the original FD or other propellers available. Anyone in Spain hit me up.

Thinking I could even loan a unit to some European members to get some feedback on performance?

Anyone interested write me a PM!

Jordi
