Re: Electric Hydrofoil/E-Foil

Hey Hiorth, how is the seal on your drive shaft working out? Have you ever found any water in there? Do you grease it before riding?

Re: Electric Hydrofoil/E-Foil

Good question! I'm not sure. Probably yes to start.
How did your test go?

Re: Electric Hydrofoil/E-Foil

Hey guys, Thanks for the kudos and tips. This is a slingshot NF2 kitefoil. I can ride it with my kite and behind a boat without any trouble (although you do indeed have to pay constant attention or surprise stall, and I can't jibe yet). I'm 165lbs and start to foil at slow speeds below 10 knots on m...

Re: Electric Hydrofoil/E-Foil

Here is a video of me trying to ride my E-foil. Warning: it may be a little demoralizing. The prop I used was designed for 14 knots at max RPM.

Re: Electric Hydrofoil/E-Foil

Hi All, I had some success this weekend with my build. I was ripping around the bay for about 25 minutes and used up about half of my 12S 16Ah pack. I found it quite a bit harder to ride while trying to maintain throttle and balance, with all the force coming from the bottom of the mast. I eventuall...

Re: Electric Hydrofoil/E-Foil

That is the gearbox I'm using with 500kV 12S. Just note it has a much lower torque rating than the 5:1

Re: Electric Hydrofoil/E-Foil

I belive the O-ring grooves should be machined in aluminium (not 3d printed) to ensure a good seal. The O-ring should be compressed about 30% to obtain a good seal, Cheers Have a look at the Parker O-Ring handbook. https://www.parker.com/literature/ORD%205700%20Parker_O-Ring_Handbook.pdf Probably p...

Re: Electric Hydrofoil/E-Foil

Hey Hiorth:

Beautiful design! so close to foiling.

Any chance you could give me the bolt hole pattern diameter for the SSS56104 please?

Re: Electric Hydrofoil/E-Foil

Hi Waterfox, How many Kv is your SSS56104? I have ordered the same gearbox has you, but was wondering if I should order the 500Kv or 700Kv? Thanks to all of you for sharing your amazing build Clarin, I bought the 500kV SSS56104. Given that pacific meister succeeded with a 500kV SSS, 7:1 gearbox and...

Re: Electric Hydrofoil/E-Foil

based on the BPhobbies Cheetah A5330-9 on 6S but I didn't have enough power or enough cooling. How much W in did you got? Any thrust measurements? What was the cooling path, considering its out-runner? It is so exiting to see real world chocking with reality! :) P.S. You are the man, so ahead of my...

Re: Electric Hydrofoil/E-Foil

Hey, does anyone have a CAD model or the measurements of the SSS 56104 motor. Specifically the bolt pattern diameter. Mine is on order but I would like to get to work designing before it arrives. I've taken a crack at this already with a propulsion system based on the BPhobbies Cheetah A5330-9 on 6S...
