I'd suggest you just find yourself one big and brawny gearmotor to use as the transmission. We could calculate a good ratio for you, based on tire size, motor selection, and the voltage you want to run. As long as we know the motor's RPM per volt, or Kv rating, and an idea of how fast you want this thing to go.
thanks Nate , she's a work horse (bone stock) I got my speed issue taken care of . when I ran it the 1st time hauling 20 loads of coal it worked OK but I had a delay between fwd and rev . so I reprogramed the esc ( castle) to eliminate the delay . Also when I hooked it back up I desided to put the trotle on the throtle stick like evreyone else ( I know ) not realizing you have to reset the radio with the esc when you change parameters on the esc . now the bone head that put the shims in wrong on the fwd rear also did so on the rear rear so I'm getting there
