New here, completely lost on ESC choice

[NoName13]

Hello,
I am looking to build my first efoil, with the following specs: flipsky 6384, molicel p42a 12s4p for power.
For ESC I was first considering a flier, then went to Flipsky 75200 VESC but I have seen people struggle to configure it, though the VX3 controller looks nice. What would be a good ESC/VESC to pair with that system?
I am looking to have a fair run time of 45 minutes and enough power to get to 30km/h at least.

Are you building a rig that will be full efoil (powered all the time) or foil assist (power aid to get foiling but power off at times) ?

[NoName13]

Full efoil, I may have over estimated the battery capacity, since I dont know if people talking about similar batteries were doing assisted or not…

[Foilguy]

I would recommend you look at some of the threads here that show successful builds for that activity (full efoil)

These are some good ones with lots of detail

Frankenstein build (Fliteboard, Gong V2 mast, Flipsky 75200 VESC and in my case a Tritonfoils X1 monofoil)

Wanted to do this for some time now, but as I’m in my test week for school I have not much time at this moment to write a full report. I’m going to post all pictures I have taken during the build, and if something is not clear, or if you have a question, then please do not hesitate to ask. I will also add some comments with the pictures when I have time todo so. But. 1st I would like to thank @MBard and @vincent. They helped and inspired me with this build. So, a BIG thank you Marcel and Vin…

Build on a Weekend

Hello everyone, I would first like to thank you all for this great community and the knowledge and help you provide. My plan was to have a functioning board for the summer as soon as possible after graduation. But as you know, I couldn’t wait until the exams were over because I was constantly looking at the parts, so I built it quickly over a long weekend. Even though many will now think that it is not a real DIY, I find the Fliteboards very beautiful. I got it for a very reasonable price, for…

I’m still new here and starting to understand everything.

You are correct with 75200 can have setup problems, I almost gave up and had numerous frustrating and inconsistent results.

However once I knew where the problems are, I had no issues and my 75200 runs well and runs cool.

For reference, the issue is using the wizard or auto configuration. You need to then go through the values and adjust them, such as max erpm, max battery amps, total watts.

I used motor amps as my only limit, and increased all the other beyond range of ESC and motor.

I basically just replaced the Foil Drive Assist Plus electronics. FD only use the maximum battery amps as their limit according to someone who managed to get into the ESC.

FD have high values for everything else, but just limit battery to 60 amp.

There seems to be different ways to control the power.

Another possible problem with the 75200 is condensation killing it, so people coat the ESC which means you need one without the case, which is usually the case to attach it to a heatsink.

I used 3M adhesive thermal tape squares. The hardest part of the build was unpeeling the cover squares.

I’m using a box and keep it open when not in use, so in time I’ll see if condensation is a problem.

I see, is condensation caused by running the water cooling loop? If it is ambient moisture, wouldnt some dehydrator packs be enough to prevent it?
Another question, does condensation appear on the VESC itself, or on its surrounding, and then the water makes its way to the VESC? If its only the surroundings water proofing would be an easy job, if its the VESC, not really looking forward to that…

I have decided to get the Makebase 75200 if I go the VESC route, or a SeaShark 200A for the ESC route.
