Motor question
 

The green motor provides no torque benefits over the orange, correct?

its hard to say the orange motor goes faster but that has nothing to do with tourque...i dont really think it does

green has more torque than orange

Dunno about the MT motors, but a common misconception about the regular ZipZaps motors was that the slower motors had more torque.

The faster RPM ZipZaps motors have more torque than the slower ones -> http://support.radioshack.com//suppo.../zz-motors.htm

Ok from what I know the motor only deals with Top speed the gearing is where you find your tourqe so the green gears with thwe orange motor should have more tourqe than the stock green/green I'll do some test when i get home.;)
