General EFoil Build Help

Hello, I’m planning to build my first efoil and am looking to get some general advice on components & setup. I’ve browsed some topics, and pulled some common parts for the list below. Tentative components & materials so far (please provide feedback on better alternatives or combinations):

Budget: $2500ish

Motor: $438.99

  • Flipsky 6kw 65161 100KV w/ stock propeller - $419.00
  • CorrosionX - $19.99

ESC: $319.00

  • Flipsky FSESC 75200 75V 200A ESC

Batteries (series): $389.90

  • Turnigy 16000mAh 6S 12C Lipo Pack w/XT90
  • Turnigy 16000mAh 6S 12C Lipo Pack w/XT90

Wing/Mast: $699

  • 2019 Starboard Wave DT 1300 Foil Complete
    1300mm front wing, 270mm rear wing, 67cm mast

Controller/Reciever: $125.90

  • Maytech MTSKR1905WF V2 - $125.90

Board: $233.90+

  • Home depot XPS 3"x4’x8’ - $49.27
  • Home depot XPS 3"x4’x8’ - $49.27
  • Home depot Aluminum Support/heat sink 24"x48"x0.125" - $43.84
  • Additional Support Boards, wood 1"x2"x8’ - $2.54
  • Fiberglass sheet 39"x16.6yards - 32.99
  • Epoxy Resin 1 quart - $55.99
    -waterproof cases, wires, & fittings TBD - +$


  • Antispark Switch Amphibia 26S 200A - $55
  • 3D print mounts/etc - essentially free, I have plenty of filament from other projects.

Running total: $2,135.79

TBH I’d prefer to purchase a complete unit, but for a $2,000++ premium I’m willing to do a fair amount of work. I’m mostly concerned about the mystery prop that comes with the motor, and if the wing I found would be an adequate fit. I’m not interested in going very fast (for now) and the closest lake to me has a speed limit, so I’d also like to be able to enjoy this while going fairly slow (10-15mph/16-24kph). And with my poor timing, I’d like to avoid sourcing stuff from China and avoid 6+ week shipping times since it’s already spring and Minnesota has a limited season for watersports.

Have you drive or build one Efoil?
No… You write and write and write, but it is no work from you too see?
You just keep asking about pruducts and data, as you have already tried to get an engine from me. That’s not fine!

I dont see any reason why the above won’t work. Just add a flite prop (cheapest, functional and quickest to get your hands on) to it and your good to go.
Search forum for ‘flite propeller’ and you should find a nice link

I think that when I write something, it is always useful information for a larger number of people. For example, here’s my work The Lift E1 eFoil thread - info for the DIYer - #105 by Dynamik or here Lancaster Build Log - #18 by Dynamik or I’m about to post the basic shape of a paddleboard propulsion system (certainly better than SCUBAJET). I am now waiting for a reasonable price from a company that is able to make me a fiberglass hull/housing for the propulsion system, possibly for other interested parties.

If you post the motor specs, I might consider designing an ideal propeller for it. This could create an ideal propulsion for, say, e-foil, assisted propulsion, or universal propulsion, etc. Propellers are always designed to the specific motor and the material used (metal, fiberglass, plastic). The opposite is not possible!!! If an motor has good parameters, that’s the reason to publish them, show them off here, etc.

You’ve been talking about your magic propeller desigs for years (literally) and yet not a single proof/experimental evidence on how great they are compared to the “unscientific” approach that everyone but you follows.

Also, saying “So all the current wings are one huge improvisation, not the result of scientific research” and things like that, is a blatant lie. I don’t see how writing these type of things is useful for a large number of people. Your posts only show that you think you’re smarter than all the manufacturers together, but anyone who’s been on the forum long enough has learn to skip your posts.

So I invite you to prove me and others wrong and post back when you have your revolutionary design up and running and show us how you were right all along


You can’t think over my engines, I think, you are not clever enough.
