I’m am completely new to this scene but have been inspired to have a go at building my own efoil by this site and all the contributors terrific builds.
Before I start collecting all the bits I need I thought I’d run some ideas past you all with how I’m proposing to proceed bearing in mind that this is just a toy for me to use so aiming at keeping the costs lean.
Motor - SSS 56114 KV360. Would it need to have a cooling set on it? I’d prefer a direct drive for simplicity. I intend to set up the motor so that it can be mounted on the board with or without the foil “ewakeboard style”. This is mainly to encourage less adventurous members in the family and young kids to give it a go. In addition, I would like to use the motor and electronics/battery setup on my Kayak as well in the long term.
Battery - I’m in the process of buying an ebike conversion kit which comes with 48V 15Ah battery with built in BMS and am considering using it for the efoil. Ideally, I’d like to set up the connections from the electronics on the efoil to suit so that I can “plug & play” the battery between the different toys. I will build a waterproof box to fit in all the electronics and battery. Can this be done? How much board time am I likely to get with this size battery? How is everyone keeping the batteries and electronics cool?
Electronics - This is where I need some serious help. I have read a lot of info about EMS, waterproof remotes, cruise controls, safety gear etc. but I’m still quite confused how it all comes together. Would it be possible for someone to share a wiring diagram with all the components required from the battery to the motor and if possible links to reliable equipment you have used. Because I would like to have kids have a go at using the board, I’d like to be able to limit the speed if possible when they’re on it.
Board - One option is to build my own with XPS foam like most of you have done, but I am not very confident with shaping of the board. Other option is to use a wave ski as a starting point as it already has the depth to house the electronics/battery box, cutting the top for the box, reshaping the front to make it more square and filling it with expandable foam and strengthening it as necessary to suit the foil. Thoughts?
Foil - Ease of riding is very important for me. From the bit of research I’ve done it seems like something similar to this photo would be suitable with a max mast height of around 700mm.
I came across this kit for sale on this site which may be a good starting point for me. Thoughts?
This my thinking so far. It may be that I’m trying to do too much but your help and advice will be very much appreciated. Thanks in advance.
