John,

Your diff and brake question is a good one! I don't know for sure, but the guys scratch building the bigger tracked machines are all using two motors I think? I would guess that getting the brakes to work as smoothly and easily as using two motors would be harder than the simple two motor setup.

As you prowl around here on the site you will figure out the handful of guys with the bigger scratch machines and they should have a good answer.

Tom,

I ordered three more sets of motors. They make three different versions of the motor in that size. I think there is going to be at least one that should work. What I have now is almost strong enough. On the bench, they feel real strong, but they need just a bit more grunt.

I think one set is a bit higher rpm and higher stall torque, so I'm hoping I can re gear for the rpm and get about what I need for speed and torque.
