Austria / Salzburg Build #3 ( slow )

[nice2cu]

Towards the end of 2021, I decided to build a 3rd efoil.
This time shouldn’t be based on an inflatable, but on a wingfoil board.
I quickly found what I was looking for at Gong and bought an almost new Gong Lethal 4.10 80l at a good price.

GONG WING FOIL LETHAL FSP PRO - Surfoil Boards

This time I decided to use an FR motor.

Motor system 5,5 kW

For the engine control I take a A200S V3 VESC.

A200S V3.2

In my first and second project, I have had good experiences with Gong foils. That’s why I’m sticking with this system.
As mast i will this time the V2 85cm CFK.

GONG FOIL ALLVATOR CARBON MAST V2 - GONG Galaxy

For the batteries i will use LG-Chem Li-Ion Zelle 3.65V / 51Ah / 180Wh.

At moment i had maximum less time, so i think my build will not finish this year.

First pictures for my parts and first working steps.

[privatpilot]

Thank you so much for the list.
I will preorder the A200S V3.2

Hello ,it’s easy to drill the mast ? Or just drill the plate? I love the gong board nice price!

[nice2cu]

No, not was so easy but in some hours possible.
Inside the CFK mast is a foam core but interspersed with some longitudinal ribs.
I bought the Wingfoilboard used for less money

The next parts are arrived.

[nice2cu]

Next steps are done.
I thought about using the original Mastclamp from FR or construct / build an own one.
I decide me for DIY.
I constructed in Fusion 360 my Mastclamps.

After them I thought about, how to produce that.
First I did a test print.

All fits. So should I CNC it from Aluminum or SLS print. So, I select SLS to try if the material is stong enough.
Here are the results:

Yes yes yes baby

[Ranelson93]

Is the SLS material you chose nylon 12 or nylon 11? I ask since LS nylon 12 prints with some porosity and may not be water-tight straight off the printer. Regardless I would suggest sealing it.

[nice2cu]

It is Nylon 12.
My plan is to laminate it outside and seal it with epoxy

[nice2cu]

After the ODU LAMTAC connectors have been delivered, the construction process continues.

And now the test print.
When all work like I want, I print it with an SLA Printer and Strong Resin.

[nice2cu]

[Jezza]

Those look good. You should pour mold them with some decent urethane and they would then be a lot stronger than 3D printed.

[nice2cu]

I not will print theme with an FDM printer.
It is only a prototype for playing.
My plan is to print the side with the pins in my SLA printer and use a strong and flexible resin.
The other side I will print in Strong X resin.

next step the two turned parts.
