Hi Jeff,
First I’d like to thank you for all the information you share and congrats on your different builds.
I have a question, can you tell me how you printed the mast clamp? Type of material (ABS, PLA, PETG…) and infill (100% or much less and later filled with epoxy)? I wonder if it will be strong enough if I print it in ABS with 100% infill.
If others used other solutions I’d ba happy to hear them.
Thanks and greetings from a French living in California.

Hello, why did you take lithium batteries instead of lipo batteries?
Pourquoi avoir changé de type de batteries entre la version 2 et 3 ?
Hello the board thickness is 10cm and the height battery box is 9,9 cm. I don’t understand, can you explain ?
(Sorry for my english)
Hi Coupli,
I changed for 18650 for the safty.
for the thickness the alu box is directly glue with epoxy with the bottom layer and the upper

02/03/2021 Prop and gong wing test
I didn’t finish my V4 Efoil, So I tested the new props and Wings with My V3.
First test : old wing configuration (curve XL) and new prop Flite
1 amp less than my alu prop and no more noise 
very happy
so 16A with this configuration
Second test : same wing, new alu melted prop
unfortunately 20A
3 test : prop flite, wing gong veloce XXL stab 47cm veloce
consumption 14A
and final test : prop flite, wing gong Veloce XL, stab 47CM veloce
consumption 17A/ 18A, but I increase the speed, and stability is better than XXL veloce
So for my mew V4 Efoil I 'll used the Veloce VS curve and the prop Flite with the cone is my better prop until now.
I’ll began a new thread for the construction of my V4 soon

And the contact between carbon and aluminum is not a problem ?
What speed you get at 18A with Veloce xl.
Thanks
And what is thickness of alu cover ?
Hello JeffM.
Nice job!! How do you power on your board ? By plugging your magnetic switch? Do you have an extra switch like an antispark one ?
Hello
what do you use as a pump for cooling, thanks
See upper on the parts list, you have the link on aliexpress
max36
=> yes I plug the magnetic switch to power on, I have only an connector XT90S
like that
You can see upper, you have the schematics
Coupli
=> thickness of alu cover = 2mm
and no pb with alu and carbone, but I use it only on a lake
toto44
=> at 18A with veloce XL 22-24km/H
that is increduíble low consuption! Nearly cant believe it. How do you measure amps?
Hello
Are you some cad or fusion 360 files of your board ?
Hi Pierre,
No sorry I shaped the board directly in a foam “styrodur” without CAD file
