I use the 120kv 65161 and the flite prop and the vesc 7520 waterproof fromflipsky. All works well no problems aft over 150 sessions.
For board the fliteboard board only is quite a deal IMO. I got the carbon pro classic and the build quality far surpasses any DIY build. I have built a lot of boards over the years but went the fliteboard as its just hard to beat.
The 120kv motor is a better solution and can handle 14s (what you are referring to as 60v). The 100kv has zero benefit over the 120kv.
The current will depend on what prop you choose, what size you are, what foil you ride, your techniques etc…
I don’t use water cooling just passive with the vesc mouited on aluminum plate atached to mast. Cooling is really good this wat. However I like the sealed vesc much less worry if it gets even a little water on it. Price is almost the same but a touch heavier than the plain one.
I was able to open your link. To do this, I needed to reload the page and quickly click on it before it changed. If you wait a little, the link stops working and leads to the main page. Looks like this is a site bug.
Thanks for the info. I read it and realized that 100KV and 120KV are almost the same. The only difference is the maximum ESC current and the winding inside the motor. So I choose 100KV to reduce losses and be able to use a cheaper ESC.
Requirements for EFoil only are different than foil assist and again if you want to do both.
My suggestion to you is either predetermine this or pick a collection of components that will allow a full range of capability. Buying individual pieces that are “less expensive” may not work out for you as they may not be up to the task that you settle on by forcing re-purchasing or at the very least a lot of initial “can’t get up on foil” problems.
Experienced builders/riders - and there a lot of them here like @jezza and @Larsb have done all that trial and error and documented the results. Ignore the advice and it’s going to cost you.
First, I’m planning to attach a motor to my windsurf boat without a foil. It has a volume of 165 liters. I’ll go for a ride on the lake and the river. Sometimes I will ride in the ocean when there are no waves.
Then I plan to purchase a foil board and, having already had some experience and understanding, attach the motor to the foil.
The most expensive thing, as I understand it, is the batteries. I need to buy about 120-140 16850 batteries to get the required power of about 6kW.
Just jump right in to foiling and save the money. You can get a new Gong xover setup really high quality for great value. Mount the vesc on the top of the mast and bypass the water cooling option. You will learn some stuff on the windsurfer but have to rebuild and almost start again for a foilboard that works. Look for a used fliteboard board only. If you can get one for less than 2k$ you win. The hatch does not leak and you don’t need to start a composites factory in your house to make several.
