What kind of manufacturing do you have to use?

Milling, waterjet, welding?

For the width of the gearbox, those standoff/spacers don't look substantial enough. What gears are you using specifically?

Looks like you used 0.25 plate for the bearing blocks, I'm guessing similar to 33 from 2011 style. There doesn't look like there's enough overlap between the 2x1 and the plate. I'd avoid running the chain below the chassis if you can help it.

The battery box looks like it's sitting on the garolite unsupported. Looks like an unbendable part as is.

At a glance, doesn't look like there's enough spacing for wires since you have the Vics, PD, Vics, cRio side by side.

I'd recommend 7075 aluminum for the driveshafts.
