How fast are they really?If your interested in buying an electric RC car then you likely have a few questions regarding what you can expect from them. The main question that arises the most kind of speeds can it reach. Fast electric RC cars, the ones that are tuned just right and have a custom engine are still no match to a gas powered RC car. You can realistically expect speeds of 30-45 MPH on an average electric RC car and 50-75 MPH on a more advanced and properly tuned vehicle.
Battery Life/Run TimeAnother factor that should be considered before making a purchase is the battery life. The battery life on an average RC car will give you 15 to 20 minutes of run time - full speed. Some radio control cars will deplete energy faster depending on accessories like working lights, alarms and the like. Check the battery charge rating on the specifications sheet to ensure it will run on a single charge according to your expectations.
Space Requirements/Where To RaceUnlike gas powered RC cars, electric RC cars can be driven/raced in apartment complexes due to being slower and the reduced noise levels no worrying about complaining neighbors! Most fast electric RC cars are built with standard street tires which are smaller and use less rubber. This is ideal if your in town and you'll only be driving on pavement. If your into offroad racing then you will need to upgrade your RC car tires to a larger size with better tread for increased grip.
