Hisun efoil remote mods anyone?

I am helping my friend @LAHISurfDoc to make his Hisun efoil rideable. Their up/down increment remote is not working reliably which makes it hard to ride this efoil.

Has anyone successfully connected a regular PWM remote/reveicer to the Hisun efoil?

I’m interested in seeing this setup. Can you post pictures?

Maybe you can just use a Maytech remote.

That’s what we are thinking. I have no pics sorry, maybe @LAHISurfDoc has some. They have a 4-pin data cable from the ESC to a little sealed and embedded box in-front of the hatch. We didn’t try to open that box yet, I assume the receiver is in that box. The display for battery status is next to that box and it seems to be also fed from this data cable. A quick voltage measurement on the 4 pins only gave me the total battery voltage (10S). I was hoping the 4 pins would be GRD, 5V, full battery voltage and PWM - then I could have just hooked up the Maytech or other receivers near the ESC where the plug is without breaking that sealed box open. Maybe still possible if one of the pins is PWM, we just need a BEC to get the 5V. Any insights welcome.

I’d say open up the sealed boxes and create a “Hisun e-foil” thread! :grin:

I just did a quick Google search and many customers complaining about that terrible controller.

A thread with pics might help someone else who made the mistake of buying this product. Thankfully, anything is fixable as you know. Worst case scenario it will need an ESC and remote / receiver I’m thinking…

Wish I had some first hand experience with those to be of more help. maybe someone else will chime in. Good luck!

I can try to do it this evening.
On my side, the 2 buttons remote works pretty fine. It’s not very precised but it does the job.
I’ve just had headache trying to unmount it to change/check battery. One of the screw did not come as expected but Hisun sent me many spare parts (for free).

I’d love to find a way to connect Maytech remote on it, it would allow me to switch to another lighter board.

Are you referring to this piece of junk?

Wow. That looks terrible… Seriously? That’s an e-foil board remote?

Yeah!!! and it works :upside_down_face:

Here is the tiny internal chip from the remote

As far as i know Hisun has tried to work out the Maytech remote v2 but they stopped development (for reason that i do not know). They’re working on their own new remote.

What a disappointment… :sleepy:

Just dig it out. That potting material is usually pretty easy to get the components out of. You’ll probably find water got in, and signs of corrosion. I would have filled the box with corrosionX and sealed it up!

Here is the receiver. I’m not sure what is managed through it (battery lcd, magnet switch?).
So questions now are:

  • is it possible to use a different remote (Maytech?) with actual receiver
  • is Maytech receiver could replace this one ?
  • is a complete mod (esc/receiver/remote) is the only way to upgrade the Hisun?
    Thanks for helping
