Submarine Build

This is fantastic build @drswitch. Thank you very much for sharing this info. Why do you think you need bigger motor diameter, did you feel that the torque of powerglider motor wasn’t enough? Can you please share the prop design?

What do you think about this motor below:

This 8072 motor has 70kv and twice of torque (13nm) comparing the 6384 motor.

The motor size is fine, I ment bigger cables. The prop design is a little problematic. I have so many versions I don’t remember which one I used… I can share some photos. Also I will check my CAD files and let you know.

Great build, congrats!

ok, than we should define a motor based on the winding scheme of the 6384PG 100Kv in combination with a 63100 motor to bring down the Kv to below 80Kv. It would have 30% higher ohmic resistance and almost the same current capability as the 6384 you use now. The weight increase by 10% is neglible. Some openings at the end bell and a drilling scheme like the 6384 would be good. Also it shall be available as DIY version without stator glued to hub so we can epoxy it easily.
More whishes?

I just saw you are from Slovenia also?
Maybe we could hook up sometime and ride together.
I will probably finish my e-foil this month.

What is the limitation of the 6384PG we are trying to address? It seems to be all @drswitch can handle. And, I just ordered 3 :face_with_monocle: The speed issue can be addressed by a lower pitch prop.

It seems to accept 90A phase current maybe 100A when cooled by water. 15 minutes. But you need to have a close look up at the duct, the hub and the prop. This is for Vesc motor current setting in FOC mode.

And why don’t we put more batteries in the large foil? Battery cooling looks to be the next issue to address. And if he is not going wide open all of the time then maybe the cooling issue isn’t as great.

I edited the video and here it is!

You got really nice riding skills! Congratulations! Its looking like that the 6374 100kv motor Is more than sufficient to ride at fast speeds.

Wow! I did not expect that this small motor can push you around like that! Looks like you are riding in Bled?
Please keep us updated.

hi,

after testing many 63 outrunner in the past the 100kv is a good choice, go to a 6" propeller and you might have a better control on it and less amps.

Next thing is your wing, it looks so small, what model is it ?

Maybe you should try something like surf oriented it will be 10X times easier to ride.

Really cool and impressive riding skills on that tiny board!

Hi,
I would like to buy one.
if you tell me the price and the times to receive it we will talk about it.
I am in Italy.

Great build.
I realy like simplicity.
Hmm, all thing is under water so with little modification you could easly cool your setup.
This is one of most interesting build here.
Bravo.

Hello…
Did you mabye finde model for your propeller?
