A build thread for Excalibur, my third esk8
How it all happened
I got into esk8 in the summer of 2018, and made a little $500 shitter board with my engineer brother that worked (kinda), and it was fun. Homebrew 10s2p 25R battery with Vruzend no-weld cell holders (interesting concept), but the issues with the drivetrain always pissed me off and the shitty chinese ESC didn’t make the experience any better. Board later has battery problems that I misidentify and can’t figure out, so goes in the garage and sits for a while. Lasted till Spring 2019.
Fast forward to March 2020, quarantine hits and I’m bored out of my mind. Ideas start churning, and I go out and fix the shitter board. (Misaligned cell holder, didn’t make contact with the positive terminal and so the ESC wouldn’t boot as it wasn’t getting 36V). Fixed it up, and bought some more shitty parts to upgrade it with (with the exception of a TB6374 motor) that at the time I thought were good because I really was doing this all on my own, no forum or anything. That board also is shit and was a pain in my ass, but was definetly a step in the right direction and was better than the first iteration. The final straw was in late summer 2020 when I got stranded on a ride and had to pull over 3-4 times within an hour to fix issues with the drivetrain. I remember getting stuck in a Target parking lot and just going absolute apeshit because I had put so much cash and time into this build and it just didn’t work. So I said “fuck esk8, I’m selling it all”.
That phase lasted about a week, as now I had discovered the forum and the absolute porn that is the pictures thread and build threads. I decided to take the cash that I got from selling everything (actually recouped all the money I had spent, luckily) and put it into an actually good build that would work right and last a long time. So, Excalibur is born.

Wanted to throw this in here. Same place, one build, and 120 days apart:
And here’s the build process, in pictures!
This thing rips. I absolutely adore it, and will be building more. Next up is a street carver on metro 155s most likely . The ESCs are great, as they are literally just rebranded Trampa VESC6 MkIII’s (lol). Battery is awesome, although I had to send it back to Artem to get it fixed (absolute legend, he fixed it at no cost and I had it back super fast, AND he wrapped it in clear!). The drives sound and feel amazing, I feel like I’m riding an electric porsche! The power is insane, and the sound is just so perfect. Love this board, and everything inside it.
Thank you to all of these people (no particular order) for helping me bring this board to life!
