That 9.87:1 Toughbox seems interesting, but if we're going to buy more Toughboxes, we might as well just make our own (lighter) gearboxes. I just threw the Toughboxes in the CAD in the event that the team wanted to save money and use the Toughboxes we already have.

If you like the gearing in the Toughbox, there are lot of weighs to reduce weight. You can mill out some of the material in the side plates, get aluminum gears instead of steel, or just cut out material in the gear sand sprockets like this

I'm all for custom gearboxes, but if you want to keep it simple, you have a lot of options.
