Just beginning to order parts to do this build over the winter. Figured by the time everything comes in the lakes are going to start to freeze If not, I got a drysuit!
Battery: Either 12s12p or 12s14p of samsung inr 18650 30q. Any other better battery choice? I saw a few people with 14s batteries, but the ESC above look like 12s max. No BMS, built as 2 6s12p pack and charge with my RC charger that can put out 750W.
Foil: I have a slinghost fkite with space skate 65cm wing for kiting. I’ll buy extra 90cm mast so I can swap between kiting and efoiling. Or I have a liquid force happyfoil. If I can find a big wing (Impulse wing?) for that, I might try that instead.
Board: Either a old windsurf board or a considering cutting one out of foam and fiberglassing. Might use a pelican case for the first try for waterproofing ESC/batteries.
You’re in the US so the ARC200 is a no-brainer! Their after-sales service is amazing compared to the other companies as well.
Definitely go for the 120KV motor. If I hadn’t bought I’d try convince them to custom wind me a 140Kv version. But a custom wind would definitely take longer to get it as they will need to test etc.
Hi! I also use the stl from @YAHEF. He did a great job providing this, many thanks. I printed with 0 infill and try to fill with epoxy; from printing quality (PETG) I am very happy about the result. I have a gong mast which was easily to adapt to the stl. Basically it should look like this from the inside:
I am trying it with a small amount of gyroid infill and no bottom layers. What what it looks like pouring epoxy should be able to flow throughout the part, and maybe will give me a little PLA fiber reinforcement…
Not sure why the video didn’t work for you. I just meant to post a link to the google photo video link because that is a lot easier then uploading to youtube for a short video. Apparently the forum software is smart enough to try and make it playable on the post.
Pretty cool little device. Not a kit and don’t need to buy anything else if you have a big 3s lipo. Korean guy designed them and builds them up. $70, but after shipping to the US and some international fees it was about $90.
I drilled two holes, one for injection via syringe and one for over pressure release. First I also had without top or bottom layer, but it actually looks quite nice when print is closed.
After already done with most of the spot welding, decided a different layout probably would have been a bit better for max current draw, but this should do for now. Looking at 10awg wire from the batteries to the esc with xt90s since that is what the ARC200 has already.
Had to use a little steel wire to fish the large 8awg wire the motor came with through the mast. Hopefully can get away with passive cooling the ESC! Or maybe mount the ESC to a plate of aluminum that is exposed to the bottom of the board or in contact with the mast.
Are people epoxying the mast holes so they don’t fill with water?
Hi Bryce!
Love your setup and it’s an inspiration for my eventual build.
I was looking at the Flipsky drawing and it looks like m5 screws - is that what you meant?
If not, I got a drysuit!
