Who is Carlo?

2WD is less strain on the drive. True. Small wheels can work with a low ratio of gearing, but the machine won't be fast. If you aim for a fast heavyweight, you'll have to look for more, or "stronger" motors.


To give you an idea. Bullfrog uses Iskra 1200W 24V motors on 10S with a gearratio of 20-1 and 10" wheels. Gravity 3 used Bosch 750 motors with 10" wheels and a gearratio of 15-1.
