Foil Drive Assist, DIY

I want to duplicate the Foil Drive Assist at Electric Foil Assist Kits | Foil Drive™ – Foil Drive Pty Ltd. It’s an lower powered efoil. I would appreciate ANY help in the build process. I’d like to start with a list of parts for the potential build. The company in Australia is retailing it for $3,400. Thanks, if my build is successful I’ll share it with others. Again, I really need help in determining what parts I need for the build. I already have the board and foil.
