I’m moving to the sea for the next month and urgently need a folding propeller
Does someone already started with a good design and is willing to share it with us.
I want to make one for the FS65161 motor mixed up with my 2-blade propeller.
I almost finished my own design yet. Today I gonna try it out. Costs: about 1€!!!
At the beginning I was quite sceptical of this one holds up or will be all over the place. But it feels rigid. There is also almost no play between the blades on the propeller hub.
It fits to the Flipsky motor without the threaded shaft.
If I’m successful I will share the files with you guys.
Ever since i first saw a folding prop and the outrageous price i’ve wondered: why don’t people just order these custom made from a machine shop? it won’t be more expensive.
There really doesn’t seem to be that much to it once you have some blades you like?
Anyway, good call in doing these, hope results are great!
I’m curious if it will have enough mass to keep the blades folded in the optimal position. Have you measure the mass between a blade from a Lift prop and on of the 3D printed ones?
Hi, guys,
this is the first working 3D printed folding propeller for Efoils. It has already been tested in water under full load (4500W). You only need two M4x40 hexagon socket screws and you can start. The propeller is designed for the 65161 flipsky motor.
It works best with the following printing parameters:
-PLA+
-no support
-40mm/s
-the wings should be printed horizontally
Wahoo !! Would you tell us more about your feeling on the water / behaviour / speed / amps drawn / comparison with other props ? Do you intend to have it CNCed into aluminium ?
I needed to reduce the pitch for designing reasons but I could achieve about 30 km/h. It’s has quite good trust (blade diameter is about 186mm). At higher speeds it will vibrate. But that’s because Its not balanced at all.
If I release the throttle completly the board will stop in short time like before. But the blades are completely folded. Also If I stop while foiling and than give full throttle again it open up the blades. For that it must be rigid. I’m really looking forward to test in waves. But that will be in October…
So please print it out and tell us how it behaves powerless
I’m really running out of time because I’m moving to the sea in the next weeks. Mabye some other forum member can do this. I know that there is already a modification for the 6300 outrunner. Ask @Ackermann
