Foil Drive Assist, DIY

I am definitely interested!

Is the box the same for the FDA and FDA+

Hi all, new to this forum but i have been taking stuff apart all my life. Sometimes i put it back together :wink:
Started a foil drive project and got the cheapest 6374 motor from Amazon.
Started to take it apart, and unfortionately the wires where glued with epoxy.
So be careful when removing the stator so you dont have to make a complete rewind…


You can see approx 10mm of one winding still glued to the stator housing. Ripped out :frowning:

Why remove the cover completely? To solder the phase wires, it is enough to move it a few millimeters.

My experience is that if you solder outside, the cables have a lot of movement at that point where they are soldered and can end up breaking.

If you weld inside it does not suffer fatigu

I was going for the complete encapsulation of stator in epoxy. (And solder on longer leads)

Sharing info that could be good to know for other diyers :+1:

Also have a cogged design of folding prop that could be fun to share:

Dont think its needed, but why not :grin:

I always solder on the outside, nothing has broken yet.

Is there an advantage for a folding propeller, when motor placed at the top part of the mast and is essentially out of the water when not in use ?

Similar question about duct. Duct gives safety and adds drag when in use, but does not add drag when not in use, considering the motor mounted at the top of the mast, right?

My logic for what it’s worth.

As the duct and/or non folding prop exit the water there is a more dramatic reduction in drag compared to a rig with no duct and/or the prop has already folded.

The inverse of course is true when the prop and/or duct enter the water

I think the goal is to make those transitions as “smooth” as possible to not disrupt the riders balance.

quick feedback on 8S3P & 12S2P - P42 with the Maytech 100A ESC. In a nutshell, it’s CRAP. The ESC saturates super quickly while reaching very quickly the 70°C temp which makes it saturate even more. In other terms, avoid this ESC. It’s money loss for what we want to do.

I’m 72kg with a 35L board and a 186mm tip to tip folding prop.

For @Jesserosco at 86kg using 8s3p 6384 150KV Maytech 100A on 56L is working fine.

Detachable motor cable connector:
Here is a little summary and I invite you to discuss

@Toto44 please can you send me stl for gong mast please :star_struck::kissing_closed_eyes::hugs::partying_face:
Thanks again

Hi, Please deposit .stl files. I can’t get .step files to read. Thank you.

Super
I didn’t see files in the folders
so okay
Thanks very much

Video of my diy system with cut down folding prop, maytech 6374 and 100A maytech controller.
The cut down prop and the 48cm Big rear wing really help reduce heating. But it is still under powered!

Hello, did you attempt a rewind? I have one here with very thin wires that were damaged from a previous project, and I would like to rewind it.

I have ordered materials to do the rewinding.
Original had 12 x0.38diam copperwire. 10 turns. Suppose to give 170 kv.
Im going for 4x 0,7 diam 11 turns. Il’l let you know how it turns out!
