About motor parameters: We default to using a 48:1 gear ratio, and the actual measurement using an encoder (with a 48:1 strong magnetic motor) shows a travel speed of approximately 0.65 m/s when powered by a 7.2V rechargeable battery. This speed is decent (suitable for most intelligent car applications). Of course, increasing the driving voltage can increase its speed, and the recommended operating voltage for the motor is between 5-10V.
