Have anyone thought of mimicking the design of the Stoke foiling with this build? Using same components but housing the electronics and battery inside one unit together with the motor. Sounds like a more efficient design with no bulky box on top of the board and less drag from the thick cable.

So the resistance of a submerged battery worries you less than thick cables?

Yes, there is a 2yo thread about it.
Sleek design but 4500usd for the Stoke system is a bit steep.
Too powerful to be plane compatible, they carefully forgot to mention the battery capacity.

Well actually they used very precise electrical language “50 starts”. You will have to Google that for a precise definition 
It baffles me they would develop what appears to be at least in the photos a nice looking product but leave out any real specifications

Don’t worry, lift has done the same on their gen 4 batteries. They’ve told everyone it can do 2.5hrs instead of giving any useful details.

I just tested the Maytech 6384 motor with AXIS ART 999 foil. ESC Flycolor 80A, 8S battery. I can fly with this wing without any problems, there is enough power, the speed is high, I am very pleased with the motor. After 10 minutes, the regulator stopped working, I will understand the reasons.

Which maytech motor is this? 6384 or 6374? What do you weigh? Which prop are you using?
Correction, motor 6374 Waterproof Outrunner 150KV. My weight is 78 kilograms. My prop is a variant of the Volker prop with folding blades.
Do you have a link to the prop blades? I can’t get enough power from the Maytech 6374 to get flying…
Can the motor get you up like an efoil without any other assistance?
Yes, I take off without pumping. Send me your email in personal messages and I will send you stl. What ESC are you using?
Jezza, will you post some feedback of how the prop does for you?
Funnily enough its the exact same prop I am already using. I downloaded it from Thingiverse and then modified the base. RTTN is 15 Kg lighter than me and using a higher volume board, but what I found in a static environment is that I just can’t get enough gas to really get going. I max out at 10kph.
ARC200, APD 120 F3x, VESC 70A are the 3 I have tried so far.
Have you got any speed data for the motor?
I don’t know how accurate it can be, but if the surface of the board and wing is too smooth, it can be a problem to reach speed. I had a situation where I felt that the board was stuck to the water. Then I sanded the surface with 320 grit sandpaper and then the board came out of the water more easily…

If you want, I can measure the thrust I get from this motor. I think it will be more useful information.
Thrust and rpm info if you can?
Not at all. You have the same worries when the batteries are above the surface but hit the water every time you fall.
I am just thinking how can we improve this design. Event the foil drive looks DIYish, meaning it has a room for improvement.
Stoke is way too expensive for what it is, but from the design aspect, it looks well thought out.
I think we can 3D print a watertight case with a rubber gasket for the batteries to solve that problem.
I think that you greatly overestimate the capabilities of 3d printers.

Rumour has it there’s a new design foildrive on the way… Not sure when it’s going to be released though.

I’ve been meaning to share this idea for ages…I started doing this design 18 months ago before the Boogie bug hit (Boogie for me is so much more fun as x practical than an assit) . If I was FoilDrive this is how I would do a V3 system.
- Weight in the best possible place
- Nothing on top of the board
- Short runs from motor/VESC/Battery
- On non carbon boards probably no need for a top side antenna.
- Great battery cooling, vesc cooling.
- Universal mounting via plate mount.
- Gives approx 25mm increase in mast height which could be useful with a prop on the mast and touch downs.
- Silicone and baking spray could be used to make a diy tidy removable seal where the box meets the board.
Issues are;
- waterproofing
- Swapping batteries easily, but a slot system from the back could work - 2170s fit between mast bolts.
- Low capacity flight packs.
- Antenna on a full carbon board probably need to come topside.
You heard it here first incase they try patent it!

Haha i have 3D printed prototypes of cases like that too but have never gotten around to building them properly. Rumour has it they system does go under the board like that, except I think it’s double volume on the batteries.
