Yes, no temperature problem with this gearbox because we use it far below its max input speed (50.000 rpm)
Chinese SUP foil received today:
It looks really huge compared to my kitefoil!
The quality looks good.
Weight 3.9Kg with mount and screws.
Next step: attach my thruster to the mast…
Looks like it will glide/cruise really well with as big as it is.
Is it a 2ft (60cm) wingspan? How much?
Front wing is 68x28cm
I think 10Kg of thrust should be enough to slowly cruise with this foil.
So only 400W with my thruster, so about 1h30 of cruise with my 16Ah batteries
That would be 3h with my 30Ah setup
Are you sure of the side of the front wing?
Yeah the way he’s configured it, it will pull him down into the ocean
It definitely needs to be flipped.
You’re right, I’ve flipped it!
Here is my custom mast clamp (inspired from Pacificmeister design’s, thanks him!):
Difficult to design because:
- thinner motor pod (45mm)
- wider and longer mast profile (16x124mm)
So less space for wires and screws!
Hope that will be robust enough…
fait tres attention a la platine elles sont assez fragile…
That is tiny! I hope it works. Where does the prop come from?
This is an aluminuim propeller for 2-3HP outboard motors. I think this kind of prop is much more efficient that homemade 3D printed ones. I hope they are adapted enough to an efoil. Good efficiency allows smaller motors, gearboxes, ESC, batteries, connectors, wires, … so saves a lot of money!
I really like that. I hope it works! Even if you need to go with a bigger motor I think the gear and prop will still work well!
Have you had a chance to water test the completed setup?
I’m working on the board for now.
I think in 2 or 3 weeks I will be able to perform first real test on water.
This is my board, an old windsurf board, cut off at both extremities:
I yet have to glue the hatch and make electric connections before to be able to perform first tests.
very nice , will be ready before me ! i believe your foil is the same as this one : https://redwoodpaddle.com/fr/foil/404-foil-redwoodpaddle-stand-up-paddle.html, take off fast…
you can reverse the rear wing depending on speed
do you put the larger plate to hold the mast ?
