I haven’t seen you mention on this current design what the slip ring solution is. Looks like a smaller bearing, so large pancake or was it capsule stacked ?
I’m going with the M220C-0320 from Senring (0320 = 3 wires 20A each).
The bearing is 55mm OD and 30mm ID and the pipe from the caster is 2mm so it will fit the 22mm capsule slip ring. My plan is to make a hole in the deck and mount the flange with screws from the top and the slip ring goes through the pipe.

And the 4 (2A) signal wires… any special plans for that?

What about an AWACS style rotating battery/esc compartment on top of the deck? Hollow caster shaft for wire passthrough. Standard issue lazy suzan bearing for the compartment. Unlimited powaaaahhhhh.

Just have a 1p battery and a single ESC on either side of the motor and let it all spin, no slip ring or special shafts, def won’t have height issues
In that version there’s only three wires no signal cables.

Would solve a lot of things with the e-freeboard for sure.
It would make riding it really awkward though because the extra mass and height
But if you have a slipring for just battery post and neg then keep the ESC and receiver anchored to the pod it would be a lot more forgiving
I want to say you can pair multiple receivers to the same mini remote and that’ll make all the wiring really easy, then it’s your call whether to use sensors or HFI/VSS

I doubt sendcutsend could manage close together 90deg bends, however it could be less precisely bent at home later probably so just skip one or two of the harder bends might be a good idea.
