Axle suggestions?

As of right now i'm thinking i'll be trying some of these asian 12v 90 degree worm gearboxes

Shaft drive coupler to bolt flange adapter things should let me get wheels mounted.

With the 4" tires these run = 1 foot per revolution, 12v motor at 7.6v, i thought 90 rpm seemed like a good starting point? I may want to drop lower speed once i see how it looks and start load testing

I got one and my BIG concern with Wormgears doesn't look like it'll be an issue. This motor does have a short coast-down to stop before it locks the output, so hopefully i won't be blowing the teeth off the worms. Since it can slow gradually to reduce stress on gears and locks when stopped, I definately do NOT want to use an esc with brake.

My other concern is that this still doesn't look like a lot of motor to drag around a bunch of steel & dirt.
