Finished printing a new version of my jumbo Velcro footstops. Heat gunned em, put on some leather gloves and smushed them into a perfect fit on the deck and around my shoes, then put Velcro on the inside. I’ll mount them to the deck once the board is put together and I can feel out my position better.

Mounts with M6x40 flat head screws
Wait a minute… Thats very clever!
It’s like, half as good as an actual binding, but you still eject normallly in a wipeout, so I think it’s safer
My steadfast assistants are trying to make sure I get the BMS wiring done before the deadline
The balance wires are all connected and routed. This strategy looks very neat, but it actually does involve a lot of crossovers where 2 of the battery packs fork into the parallel line. I’m handling those junctions by potting the area with e6000 to immobilize the wires, as well as stuffing pieces of kapton tape between the different layers.
Here’s the busbar assembly getting prepped and installed in the enclosure
I made it through another round of inverse bomb defusal without blowing myself up. If anybody needs just like, a big pile of xt90’s, hmu.
It’s alive
Remaining items on the to-do list:
-connect balance wires to BMS
-mount foot stops and legstick to deck
-mount pinion gears on motors and mesh with wheels
I could use some, PM incoming…
Holy fucking shit it’s put together and running. Still needs the footstops, but that’s quick, and I should be able to test ride tomorrow evening.
Crazy Shit…

Ride it to my workshop 
Adam already paid for em, sorry
I’ll see how I feel about the board and let you know lol
BOTY 2027 is gonna be lit with this and Bence.
Damn this is frustrating. I bolted on the footstops and spun the motors up on the bench
You can see that upon braking, the right rear just started freewheeling, and you can hear a pop just before it finishes coasting down. I tried to accelerate again and it wouldn’t spin up. I caught a whiff of the magic smoke leaking out of one of the enclosure ports, so I pulled the loopkeys. I fear that she’s fucked, gents.
Noooooo!!! Such is DIY! 
My settings for all ESCs were FW6.02, +80/-60 battery, +120/-120 motor, running HFI. I don’t think it even got close to max eRPM back there, so a random ESC lemon failure seems unlikely.
Each side of the board has a close connection to either the high or low side of the battery, then a 1m long connection to the opposite side through a bus bar. Maybe that’s too much inductance, and I should have added more capacitors? Hopefully I can figure out the failure before buying another Solo and frying it again.
Maybe it is. Looks like you got a voltage spike when braking. Add some capacitors to the vesc battery terminals or move all the vescs to the back and extend the phase wires for the front motors
Option 2 isn’t possible since the heatsinks and batteries can’t move, but I do happen to have a bag of low ESR caps lying around. Guess it’ll just be for next year’s race though
You have VESC Settings FOC > 25khz ?
low ESR Panasonic ?
