Got the tracks refit with steel pins. And, put the 1000:1 gear motors on it.
I think is is just a bit slow now, not much but a bit, especially in reverse?
I already took teeth off of one gear in the left side drive motor, so I'm going to find a way to run a bit bigger motor, faster and use a bigger spur gear to maintain the wheel speed close to the current video.

Good thing it is fun to try stuff, make it go, break, and repeat!
