Hi folks, being the request for 3d printable prop always actual and maybe interesting either for newbies than seasoned Efoilers, why not to gather here some design for the community?
I do design with Solidworks starting from a JavaProp sketch, 3d print in PC-Max (polycarbonate) or even in PLA and then I smooth the surface with sandpaper and epoxy. If the blades are thin (desirable for performance/efficiency) I do laminate a patch of fiberglass on both sides, just to reinforce the junction hub/blade, doesn’t matter to cover all the surface, after I will smooth all by sanding and glassing with other epoxy. Takes some time and effort but the result is worth that extra sweat.
this will be my next.
The hi pitch one, tested by some users already:
Now some render of the first listed, which I’m eager to try!
Just as “disclaimer”, I use a race type kite foil (580 Moses Vorace wing), big kite-race Royal board (dinosaur from a forgotten era), long mast (1mt) and 360KV + 4:1 SSS/Neugart combo, powered by 12s Lipos for now. Last but not least, I’m not even 65KG… which make sense for what above.
New design will come, I wish this could start a good thread.
I’ve some “Solas outboard 71/4” design also…not tested on Efoil but on a boat… if anybody what to give those a try. Diameter 182mm however…and the hub is the original.
