Thats really good! I'd love to see the internal design. Have you used a large thread from the mast mount to casing?

Or any other alternative for the Seaking 130A?
I have the Yep 120A. I haven't used it in the water yet, but it should be fine with sufficient cooling.

Was it quite cost effective or expensive?
Did you just glue the joint between the housing and the mast mount again?

The V2 is looking fantastic! Did you do the machining and anodizing or did you get it done elsewhere?

Re: Electric Hydrofoil/E-Foil

I'm still not sure which hydrofoil I should buy @Alibaba. Should I go for the SUP Foil (1) or the Kite Foil (4) ? I ordered the n°4, because it's the NF2 Wakefoil of Slingshot, so you can find a lot of videos with it, and I ordered differents sizes of mast to test the foil at the wakepark. I think ...

Re: Electric Hydrofoil/E-Foil

About the mast, I think that an aluminium hollow mast with a plate is the easier choice for a reasonable price, even for a personal wing setup. Could you tell me if you founded good links for that part (and maybe with a fuselage). I founded only filled aluminium masts. The Slingshot hoverglide mast...

Below seems like the right sort of gearbox spec to me - you never know with second hand parts of course. I have given it a go as only 60 Euro (accepted offer). http://www.ebay.co.uk/itm/NEUGART-PLE-40-i-8-PLANETENGETRIEBE-SERVOMOTOR-B-R-Bosch-Lenze-Gearbox-Getriebe-/332343178078?hash=item4d6132735e...

Re: Electric Hydrofoil/E-Foil

Going foiling (hopefully) tomorrow. We have never foiled before, so it will be interesting, but we have some experience with water sports, so I guess it will work out. Will start with the next version (V2), a 18650 battery pack and counter-rotating propellers (for fun) next week. Would be glad if s...

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...

I want to urge all of those building to maybe do a waterproof test with the motor unit. I found that mine was not sealing properly and as a result it has potentially saved me a considerable amount of money! If water gets in and even if the motor doesn't go, your bearings will definitely corrode in b...

Re: Electric Hydrofoil/E-Foil

Well done to all making great progress on this. Very impressive. (Winter project for me I hope) As an observer it seems to me the motor/prop creates a moment that isn't planned for in the foil design/position/angle. Especially during acceleration phase perhaps. As a result the weight of the rider s...
