Here ? https://www.prop-shop.co.uk/
The shop burned back in 2017 when i wanted to start my built , it seems open now !
@maxime_ecn , you should have enough power 
Nice, i’m curious about this propeller, keep us updated

It’s quite a power-hungry prop, but with a foil it should be a bit different beast altogether.
One recommendation for your setup is to make sure both the gear and motor are properly heatsinked. I noticed when I tested the setup that both produce a bit of heat. I had started cutting the aluminium pieces, but never finished.
where did you purchase that green prop ?
it looks very nice
Hi, i made it myself with my 3D printer. Not tested yet

Above 50kmph (30 knots), falling off the board could mean loosing a eardrum + soar neck. Kiteboarders wear a helmet that hide ears (for ex Gath helmets) otherwise earplugs. That’s where board foothooks become useful NSI Foothooks otherwise we will soon see efoil riders holding a leash attached to the board nose like esurfs.
Foothooks are expensive. It’s possible to make DiYs using a PVC pipe (and hot water) filled with epoxy resin for extra stiffness and durability.
Hey guys, I need an advice on mast length.Currently i have 92cm but it seems really high. Which length is the best?
That was exactly one year ago so opinions might have changed. New foilers appreciate 65/70cm. The ones used to 90cm either regret their lost 90cm or don’t want to use anything else. To get best of both worlds, buy a cheap 65/70cm and adapt it. Once you feel confident, try your 90cm mast. Choice is luxury.
Then there is the cable length issue: don’t cut your motor cables too short if it is possible.

I tested 45-50cm and 60-65cm
45-50cm was short and my motor often ended up spinning in the air…
I feel 60cm-65cm is a great length and easy to carry.
Thanks for your answers. I will try at 90 and cut it if it’s too long
Beware that the thread is often 3/5 cm long on each side of the mast. So cutting = making 2 or 3 new threads.
Never seen one: could you post a pict of the Horue mast airfoil section with chord length;max thickness and screw hole distance 
It’s not a horue mast, bought it from ebay at a very good price : https://www.ebay.fr/itm/113672072772
see the link for specs.
They also make the black part to fix the mast to the board for 77€ (they have an efoil version with 3 holes for the motor cables)
The brand is RLboards you can contact them on facebook

By 'Black part to fix to the mast" I suppose you mean the plate.
49 then 45€ is really a very good price for such a long mast. Gong is 79€ for such a length but their plate cost 29€. So mast + plate price are comparable for both manufacturers.
How much did they ask for the shipping from DE ?
It is very interesting to follow the evolution between 2017 until now… they have inserted a ‘I beam’. They offer a high wall thickness comparable to Axis masts.
[Edit] Thanks V_S for mast and wall thickness of this RL Wind version.
15mm as shown, Wallthickness ist 3mm +0-0,1

Yes the plate sorry 
Yes it’s cheaper than what you can find on aliexpress etc. I think it’s a great source for efoil parts.
For the mast shipping was free because i have a friend in germany (i’m living in France really close to the border).
For the plate i paid 12€ shipping to Germany and they were asking 22€ to France.
If i remember the mast was sent directly from Czech republic.
The 45€ deal for a 90cm doesn’t seem to be available any more.
Looking at the FB page.
Maybe an old stock…
Looks great!!! Glad to see it’s taking shape.
