Why resolder it, is it shorted?
One of the cables snapped off right near the stator housing. Figured if I can take it apart I can just replace all three cables.
is the black housing actually threaded to the stator? It’s hard to tell in the pictures if the housing sleeve goes all the way up.
If its not screwed together, which I dont think it is, I would heat it up with a heat gun and beat it.
It does go all the way up. It’s very hard to tell if it’s just a top piece that’s threaded.
My guess is the housing is not threaded to the stator. It wouldn’t make sense because the housing is aligned to the stator with the pin and you can clearly see the alignment slot cut. I would try and heat it up with a heatgun and pound it out like in my demonstration video.
It looks like there is a very small lip to make contact with a socket or bearing removal tool, so make sure it fits really good on that lip.
Hi everyone,
Happy to share that I found a perfect nimble ESC which fits very well on the width of the box.
Flycolor XCross 160A. 2 heatsinks on it, one is connected to my outside heatsink. You’ll have to weld motor wires at 45degrees and go !
Firmware is BLheli32, lots of settings and easy to adjust with a cheap USB tool connected from the ESC and my phone app.
Good for heavy riders

BLheli32 - that is a drones thing.
Which software you use to tune it ?
You connect to it by usb? Can add a bluetooth adapter to it in order to connect without opening the box?
Can you tune the start up current?
Able to save logs?
Does it include BEC?
Please explain and put pictures if possible - how did you attached the external heatsink to the box and attached it to the esc.
Please update us with the actual performance in the water…
As I collected information for the build, I have created this knowledge base. It is in it’s initial stage.
I would love if it becomes an ordered and accessible source of information for all of us and especially these beginning their new build.

Software : Blheli32 Android open source app
Hardware : Aliexpress Blheli USB programmer connected to my phone with the “3pins esc to receiver cable”
Bluetooth: Not found
Startup current: Rampup power in % and Acceleration in %/ms and max current also
Save logs: No
No Bec
I only use plug and play ESC, very powerful and sensitive trigger. Don’t know Vesc
Heatsink: Cut your box, cut an aluminium plate to replace the plastic meat you removed, and stick the back heatsink of the X cross on it with thermal paste.
I’ve nothing special to tell about performance because it’s a foil assist, I don’t measure anything, just burst and take off and use it sometimes longer to go offshore, it handles the temperature very well.
I’ll put some pictures later

I’m looking forward to seeing the pictures. It sounds great and it is good to hear of other inexpensive options.
So you disconnect the cable from the receiver side and connect to the programmer, or you have a T there ? It is actually two wires that active, right ?
I only use plug and play ESC, very powerful and sensitive trigger
Do you mean this Esc is PNP ?
Sensitive trigger using this ESC ? And it cannot be tuned in the settings? The Acceleration setting cannot tune it? What are the impications of sensitive trigger?
How do you isolate the box around the heatsink?
weld motor wires at 45degrees
What do you mean by 45?
What remote do you use ?
What battery configuration do you use ?
What motor do you use and how did you care about waterproofing?
How do you check the battery level when surfing?
Question about Flydragon 12s 80A/150A , @gzmann, @tosh.jah and others who use it:
- Did you try both of them, do you get a sense that 80A is enough?
- Are you able to set soft rump up current or is the soft rump built-in?
- It is hard to find a manual for these things…how do you know how to program it?
- Can I just use it as is, just make a hole in a box for it’s radiator or it’s body to protrude outside and glue it to the box, here are the body variations:
I actually have and have used all 3 of them. I was using the top 80amp version for most of the year - actually efoiling. I would probably fall every 5-10 minutes as I am always trying to improve my foiling skills. This might have helped in cooling it down. I do have a cooling plate glued to the outside of my box and with the hole inside use double sided thermal tape to stick it on. It seems to do the job.
All 3 of these ESC s do much better for cooling than the other 5 different makes/types i have used.
Only on the 150a flydragon can you program the soft start in. That being said , I prefer better control of the starting , so I dont use/ prefer it.
All the manuals are available on line. They are not difficult to program, but you do have to read instructions several times.
I only use flycolor now. They are plug and play!!! I got tired of the VESC system

Collaborative ? What a great initiative ! A Foil Drive Assist DiY is a clear first step for anyone wishing to enter the small world of efoiling.

With a bit of tinkering, it should be possible to maintain a fairing along the mast trailing edge with a strap.
here @pablo_foil Pablo setup.
Did somebody try to 3d print the Box ?
(TPU sealing?)
These 80A hv cost $30 on Ali, are they good?

It can be very cheap but great build with the 6384 motor for $55

Seems like previous model of Foil Drive didn’t have telemetry on the remote, people had to look at the box for the battery percentage. It mean they didn’t use a VESC.
I am courious what did they use…
Here ya go!! Let me know if ya need anything else.

Yes they are good I have bought several of them and others I know have as well.
They are used - some more than others— but they work well.
I spent over 1000$ on different types of esc and the one I use is 30$ hahahaha
That motor is the same one I bought. Cheap but has lasted months for me. Replaced bearing with hybrid bearings.
