Our goal is to break down the build and make a machine that is safe and runs problem free. We are focusing on using high quality parts and designs that won’t break our bank account.
We have a few VERY exciting improvements on the electric hydrofoil concept that’s going to change things dramatically but these concepts still require more details to be figured out, thus the reason we are here to start sharing our build with you for insight and help.
I’m Peter from Hungary. I’m on the beginning of my builds.
I want to build an electric surfboard with jet drive, and an universal e-propulsionsystem for beginner windsurfer. (The prop has to be here very tricky…)
I plan to use 8S configuration but with a 790 kv SSS motor.
I want to use as many 3d printed part, as I could.
(Sorry for my bad english.)
Yes there are two electric hydrofoil board patents in the USA that more or less locking up that area for “complete setups”. One has a way of steering (the older patent), and the one you linked to above is what Nick Leason for Lift foils has control of if I’m correct.
They found a way around that first patent by removing the option to steer the board and said you just use your weight to steer, and they added a “rear strut” (mast) to the hydrofoilo board. It took that patent two attempts to get it and they did. But really, if you are creative and want something bad enough, you can find a way around most patents with a little few brainstorming sessions.
Last year we’ve developed our own hydrofoils. This was the first time tried making our own foils. Bij printing the foils, filling them with glue and then using carbon makes them really stiff!! Each foil lifts around 1000N, with a resistance of 100 N at 7 m/s, which takes 700W.
