Clay composite chips can be quite expensive and difficult to find due to their popularity. These chips usually are in weight ranges between 8 grams and 11.5 grams and are casino standard 39 mm diameter.

The slot less and brushless motors are third generation motors. With slot less design, motor can achieve higher efficiency, torque, fast response time and longer life time with greater with zero maintenance. Cogging problem is also eliminated even at lower speed operation. But since there is a lot of research and development involved in their development they come out as expensive solution in case of RC cars.

There are also sensor less and motors with sensors. Sensor motors are older technology with less cogging, less rpm and less power. On other hand sensor less motors are newer technology with more power and more rpm. Both have difference of cogging on start up. This can prove to be a little troublesome when you are in a race. It seems like forever for a sensor motor to start up. But sensor less motor gives smoother throttle response, efficient running and a fewer wires to mess up with.

Remote control cars have a lot to do with motors and their functioning. When preparing for a race, checking out on motors can be really helpful. If your car is heavy then may be a motor with more torque would be required. A speedy light action racer would need a greater rpm. Connections and wires to all motors need to be properly fixed and checked. If you have some cash to spare for race then going in for slot less motor can be good idea.
