Hi, refugee from esk8.builders here, I was amazed to find the efoil branch, like many others I have been watching & enjoying @pacificmeister’s youtube channel.
Anyways yes esk8 loves the VESC (and it’s non copyrighted derivatives). In terms of cooling there is commercial options from a company called 3d Servitas based in Lithuania.
The owner is on ES -
His son is on esk8 builders and has worked with his father to design a case ystem for the Focbox which is probably the best price-point Vs quality VESC 4.12-based direct fet controller H/W out there right now, they have just completed a design and are making focbox controller boxes right now
No affliation, just a customer
