@g.gregory8 let me know what batteries you end up buying because I am struggling with nz laws and import taxes on lipos.
Hi !
It’s can be brake on top.
Mast and the boart consol ist too week.
Put more carbon!
Hi,
There is an aluminium reinforced joint going through the board. The mast will then be layered in 4-5 layers of fibreglass and 2 layers of twill weave carbon

@DavidC I already have 2x 6S 8000mah batteries I use with my UAV setup I will use. I got these from ChinaHobbyLine, but you have to request for them to send from there US warehouse. They tried sending from Hong Kong warehouse first and it was turned around.
yeah i had 2 batteries come from hobbyking from the aus warehouse and the customs taxes where the same price of the batteries. Safe to say I sent them back to the seller.

Hey guys, the build is coming on good!
3d printed mast in PLA with 4 layers of fibreglass is extremely strong! Still 2 layers of carbon to go on it 
.
Board and foils are also coming along really well, we are taking our time and still looking at electronics.
Cheers, David.

Great could u send us more pictures of mast and foil ?
I didn t understand why u printed front and back of the board ? is this to have space to put electronics?
regards,
Hi there, the reason for printing the front and back was because the board is fully designed by myself.
printing the front and back and then gluing them to a block of foam in the middle gave starting curves to then replicate through the board. the rear of the board also has a hatch that in inset into the board and houses the electronics. yes I would be happy to send more mast and foil pics when they are finished.
cheers, David.

@DavidC I think I’m going to do the same, I.E carbon fibre over 3D printed centre.
How is the flex of the mast?
How’s your build going?
Hey Glen,
My build is going good , so far the mast has 4 layers of fiberglass and is really strong. Two layers of carbon too go should take all the bend out of it.
Try trade me for fiberglass and carbon ! There is a cheap supplier in panmure. 40$ per meter carbon and 65$ for 10 m of glass.
Let me know if you need any more info .
David.

Hey @DavidC,
Im a 16 year old from Wellington starting on my own Efoil build. Loving all the progress you’ve made so far. Do you think you could please post the links to the STL files for the mast? Im also building the foil from scratch and your idea looks like it works really well and id love to give it a go. I was planning on shaping the foils themselves out of foam and then glassing/carbon fibre over the top.
Thanks for the updates,
Edward

Hi Edward,
best of luck with the build, I will be posting more updates over the next few weeks.
are you planning on printing the mast and foil?. If so check out grabcad for files.
Grabcad mast: https://grabcad.com/library/kitefoil-hydrofoil-1 You can print it multiple times for different
lengths, but I would not recommend printing over 100 mm in height to keep the quality high also I have
printed the front foil but fear it is not big enough so I suggest finding another or designing your own.
Sorry the efoil forum wont let me upload my stl files for some reason.
10% infill 3 walls and 50-80mm/s PLA- 195 Bed-65
Cheers, David & best of luck, hola if you need any help.

Hi Edward,
I have an Anet A8. Very cheap machine but requires a little love and care to get it running. Print some upgrades and buy some cheap parts and you will be sorted. You will learn a lot about 3d printing too.
Cheers,David.

Latest updates! Built a vacuum bag system for carbon/glass impregnating the foils.
Because vacuum systems are extremely expensive we bought a 12v car tire pump and re engineered it to create a vacuum instead of pressurise a tire. We then bought 6$ vacuum storage bags and so far works great.
We also put the last layer of fiberglass on the board.
