DIY Foil Drive Assist and Downwind SUP Foil Board

This is a project I have been working on for the last 6 months. I initially wanted to build a DIY foil assist to help me get onto waves earlier with my SUP foil board. After a few tweaks, a lot of help from people on the foil.zone forum and a lot of 3D printing, I had a working prototype.
I then began to see the new down wind sup foil boards hitting the market. I thought that this sleek shape would compliment the foil assist perfectly to get extra speed and even earlier entry onto a wave. I set about building a 6ft 8" by 25" down wind sup foil board. Swift foiling helped me out with a shaped EPS blank which I then sandwiched with cork and carbon fibre under vacuum to make a really nice and light board. This board with the foil assist, is amazing. I can now catch unbroken waves with ease and can enjoy conditions that were otherwise impossible for me to have fun in.

Excellent job and nice video! I have been planning a DIY foil drive for a little boost in the surf and for DW. Good to see the success on yours!

@jamesdixon2219 Год назад

Thanks. I’m still using it frequently and it is still working well. 👍

@jldsurf1983 Год назад

Great stuff James. Making it look easy. 🤙🏻

awesome video! I really dig the dig the diy electronics + foiling vibe

@jamesdixon2219 Год назад

Thanks 👍

Amazing mate what a inspirational film

@jamesdixon2219 Год назад

Cheers Chris. A lot of hours work but good end result 👍

Cool build and great video! Very inspiring 👍👍 For the non engineer/handy types of people (asking for a friend) would you mind doing a video or blog post on how you sourced the parts from which supplier on Aliexpress and also your process for the 3D Printing?

@jamesdixon2219 11 месяцев назад

Glad you like the video. Unfortunately I haven’t got the time right now to do a video like that. There is quite a lot involved. None of it is particularly difficult and all parts are readily available. The best source of information is foil.zone. That is where I started.

Great idea on the dw board. Epic you can make them. What’s ya thoughts? Motor powerful enough to efoil? I was thinking a battery on the backpack. Such a cool space the diy efoil. Thanks for video!

@jamesdixon2219 4 месяца назад

I have since built a few different versions. All still with the 6384 120kv motor. To Efoil I use a higher voltage battery. A 10s2p or 12s2p is enough to use mine like the gen2 foil drive product on a prone board.

@tdubmaui Год назад

Very cool, I'm trying to build a similar setup too.

@jamesdixon2219 Год назад

Good luck!

@thruthfultodd Год назад

What cabling did you use for the 3 phase wiring on the motor. I’m almost there. Also which waterproof box is that?

@ptj6412 6 месяцев назад

have you thought about purchasing the new GEN2 Foil Drive Assist? Are you still happy with your DIY version?

@jamesdixon2219 6 месяцев назад

I’ve been through a few iterations since this video. The latest is as powerful as the gen2 and I have built a prone board that takes the faux drive internally. I’m really happy with my DIY version. 😃

@glimpseireland2005 Год назад

Unreal, well done!!! How many litres in the board do you think, and what weight?

@jamesdixon2219 Год назад

Thanks. It all works really well together. I was quite surprised! It is 125 litre and weighs 7.2kg with deck pad, foot strap and leash. Probably around 6.8kg without.

@elchiminero 4 месяца назад

great vid mate. . . . what motor did u end up going with?

@jamesdixon2219 4 месяца назад

Thanks. I use a 6384 120kv BDUAV brushless and sensorless motor. It works really well for this application.

@kriscsandli2147 Год назад

Great Video. Are the CAD files available you used to print?

@jamesdixon2219 Год назад

Thanks. Absolutely. You can find the stl files in my post on foil.zone here: foil.zone/t/foil-drive-assist-diy/12927/355 My username on there is nekitesurfing

@davidrimmer1986 Год назад

I joined foilzone with an interest in building my own e-foil. To save me reading though 100s of pages are you able to link to a parts list/ websites etc? How many hours would you expect a self build to take after all parts have arrived?

@eligrinfeld8782 Год назад

I love the engineering behind it but would also be interested in the list of parts to save hours of researching them. I would donate some money to compensate you for your efforts.

@GreggOwens25 11 месяцев назад

Same! Great idea@@eligrinfeld8782

@guenaetienne561 Год назад

Hi, currently doing my own too. Do you confirm a 8s3p battery would fit with the 150A flycolor controller in this box please ? I m currently choosing my controller. Tks a lot

@jamesdixon2219 Год назад

The standard Flycolor 150a esc is meant for a maximum of 6S so will not be ok for your 8s3p. You need an esc that will work with 8s. Are you using 21700 cell batteries? Do you have a BMS on discharge? If so, what is your max amps? Let me know as I might be able to suggest an esc that fits your specs.

@guenaetienne561 Год назад

@@jamesdixon2219 I have a 8s3p with BMS only for charging, Molicel 21700. My motor is a 6384, for the moment I have the flycolor flydragon V3 ESC 80A, but nothing is connected, I just received everything today but I think it's risky for my battery to use this simple esc. Let me know what do you think. Cheers

@jamesdixon2219 Год назад

@@guenaetienne561 that esc is fine with the 33.6v you will get from the 8s. I think it’s max for bursts is 90A. If your cables and connections allow, you have the capacity to be outputting more amps than that. I have not tried that ESC although I do have one on order for a 7s3p battery I have with an 80a discharge. The ESC I’m using is a Hobbywing EZRUN MAX6 V3 which is fine with 160A but does cost more.

@richyandliz4802 Год назад

How much did it cost to build the foil drive?

@jamesdixon2219 Год назад

Around £700.

@remyruff Год назад

Wow that's massive difference to foil drive

@jamesdixon2219 Год назад

@@remyruff it really is. All except the 3d printed parts can be bought individually on AliExpress. You just need the time to put it together. Local e bike battery builders can build the battery.
