Your electric car will come with instructions on how to change the brushes on the motor, as well guidelines for how often.  Remember, if you change the brushes on your motor, be sure to break it in again. How often you replace the brushes—and the motor, for that matter—depends on where and how much you’re running or racing your car.  Generally, a motor should be replaced after it has gone through five or more pairs of brushes, but it will always depend on the individual car, its motor and how well they’re running.

Nitro RC’s

Nitro RC cars are named for the special type of fuel that gives them and their motors such kick.  Though not the best choice for beginners, they are the choice if speed and power are what you want from your RC.  The great popularity of nitro RC cars and trucks is due not only to their speed, but is also because of the realism they offer—sights (smoke), sounds (tuned pipe) and smells (exhaust) just like the real thing!  Over the last several years, the quality of nitro RC’s has been greatly improved, making them safer and more reliable than in the past. 

There are four defining features of a nitro RC car:

·        special nitro fuel

·        high horsepower nitro engine

·        tuned exhaust pipe

·        Realistic, replaceable air filter.
