Hey there,
I’m currently building (collecting my parts on the web) my own E-foil. I have experience with the Vesc and electric batteries and build some esk8 and DIY outboard motors with 15kW motors. The whole surf and foil thing are kinda new for me and that’s where I kinda just go with what I see and read from others.
What my parts list for now is…
Electronics
Flipsky 200A VESC
Flipsky 100KV inrunner (with the standard prop)
A battery from an electric VW car 25Ah 12s Li-ion capable of 200A no problemo.
10KG 36x12x15cm
An Arduino on a custom PCB to take care of some safety things as lowering the PWM signal to Vesc if the safety cord came off or the BMS gives a low cell voltage. Also, this is going to take care of the precharge and the pump, measuring possible water leakage, temperature, LCD, indication light, and so on.
Propulsion
the Flipsky prop
The board its self I’m going to custom make, I have experience with epoxy, so with seeing some make your own surfboard tutorials I feel confident of trying to make one or maybe two.
My questions
What foil should I use, I couldn’t really find anyone posting some square centimetre value so I just went with something close to the ones from Lift (1300cm2 or 200 square inch).
I found these 3 on Aliexpress but would any of these work? I know that rider experience is a thing but don’t really worry about it since I have some wakeboard/wakeskate experience so if the learning curve is bigger I don’t mind. I’m aiming for a more efficient foil rather than a fast one, so if these appear a bit bigger (+/- 1500cm2) I was thinking that that wouldn’t hurt for the efficiency because of the slower foiling speed.
First, because of the looks.

Second, because of the price.

Third, since its closes to the Lift foil size.

Also, any advice on the Flipsky motor mine is still not shipped so can possibly switch to the 120KV if that would be better.
Thanks for reading my long story and your possible feedback.
Greetings a new foiler.
if there is any interest in the VW battery or PCB just let me know.
If curious for some of my projects and possible project updates.
