the most irritating thing about that prop was it came with a 12mm mount. I had to print an adaptor for a 10mm shaft.
As i have a custom short shaft and the front cap acts as a spacer, my shaft doesn’t even touch the prop… instead it’s screwed from the front to the motor itself. It might be a slightly wobbly…
My plan is to thin the from cap, slightly slide the shaft toward the prop so it centers is properly.
and 80100 have 12mm shafts 
You can buy this propeller with 10mm adaptor et the pin but most offer is just the propeller
Do you have a link to the adaptor?
after a few weeks in the dust, new board is coming along…
all hotwired from a block of polystyrene, Plywood stich&glued for the electronic bays that extend inside toward the back and the foil screws to it. each bay is watertight from the next.
Old mast had some issues… new one is perfect, quite thin and plenty of space for the wire… but new motor holder needed.
The Plexiglas windows will have some round hatch for easier access.
it’s all filmed for a movie coming… after first flight!

I was thinking for an easy stand that you could quickly attach and take apart. I couldn’t come up with a good idea.

yes… with the weight of the board, it’s a pain to attach the foil… i was thinking tall sawhorses may be… that photo tripod thing work great to hold it, bot not stable enough when trying to attach the foil…

I don‘t care that much about the surface of my board, so I just flip it around to work on the bottom. Everything has to be secured in place though.

I do the same… with pad on the deck, you’re not scratching anything, expecially on sand or grass! Inserting mast under the board it’s not easy with my track system
regarding pad… What did you use?
i’m so happy with my paint job, i didn’t want to hide it so i’m waiting to receive that: https://waal.co/
i’ll put feedback if it does the job 
I use thin eva pad, 2mm thick, for dingy and cathamarans.
Such a good looking board mate, nice work. Look forward to the movie.
Board’s almost ready to hit the water…
finally installed the “anti slip” thing… i don’t know if it works well, but for sure it looks good!

Amazing work!! Do you plan to pull the batteries out? Or charge them through the port hole? What sort of electronics did you pack in front?

There are 2 separate electric bays: one for the batteries and one for the electronics
I’ll have to take the batteries out for now to charge them, it’s closed with bunch of screws, i might add a second hatch later on to access the batteries without unscrewing the Plexiglas.
Below is the electronic package, being assembled, not all connected yet:
same components as for the prototype, but i replace the power analyzer by a 350A TK15 Professional Precision Battery Tester. I didn’t power it on yet.
and i’m still wondering if i leave the water cooling on all the time or only when the temperature of the ESC pass a certain threshold.
What reason do you have for removing the sensor from the motor? Doesn’t the ESC rely on feedback from the sensor in order to drive the motor more efficiently?
Wicked build Mat congratulations! are the containers 3D printed?
Post a ride video as soon as you’ve got one!!
The sensor doens’t seem 100% necessary, most ESCs i saw were not made to handle sensors.
But most importantly i didn’t want to have to manage the connection and waterproof all those extra wires.
