Yes, there is some loss with all of those gears, but I think that it is a
small price to pay for not having to worry about the vehicle veering off
course because of a mismatch in motor speed due to the direction the
motor is working. I believe Leo's original design used the lower torque
motors, so a little loss was acceptable.
