Motor

Most any motor rpm will work, but then you need to pay very close attention to the # of teeth on both the driven and the driver gear.
I selected the 460 output rpm of the Polou 25D. It would have been a lot easier if I had used the next higher rpm which was about 1,000 . That would have allowed the 2 gears to have been close to the same size. Do not forget the diameter of the motor when choosing gears. Mine gets very close to the axle.

Is $21 a reasonable price for a motor? Is 460 rpm good enough?

I will be using the Polulu 25D (6V), which retired1 recommended, but I am still deciding which rpm version I should get. 460 rpm was recommended by retired1, but I think it would be safer to go with the 2150 rpm, which is the highest rpm without an encoder. I can always use gears to slow down the Buggy. Or, all are of the motors the same thing, except they are geared differently, having greater or less torque depending on the rpm chosen. I'm open to suggestions of other motors as well, since I have very limited experience in this.

I see a lot of 6v motor auggestions. Any 12v motors working well?

I'd assume they are suitable...
