RC race cars come in two primary forms: the battery-powered models and the gas powered models. Gas-powered models, called nitros, are capable of travelling substantially faster than their battery-powered counterparts, making them a popular choice among those looking to race their remote-controlled cars. While any RC nitro car can be operated at high speeds, choosing the right car and working to make the little adjustments which ensure the best results are essential parts of successful racing.

  1. 1

    Choose a smaller scale model if looking to have a faster car. The 1/8th scale models use an engine nearly twice as powerful as the engines in 1/10th scale models, making them harder to control and poor choices for beginners, but capable of much higher speeds for experienced drivers.

  2. 2

    Check on your RC car's air filter, which keeps dirt and debris out of the engine. The filter will become dirty over time and should be replaced regularly, as a dirty engine will be slower and more prone to breakdown.

  3. 3

    Use a standard alkaline battery for the glow plug, as rechargeable batteries can lose their charge over time, leading to decreased performance.

  4. 4

    Adjust the carburettor's low-end adjustment screw based on the car's performance. Skewing toward low end power will increase acceleration at the expense of top speed, while a higher setting will yield higher top speeds against lower acceleration, better for open courses with long straights.

  5. 5

    Replace the batteries in your transmitter before any races. Losing power in your transmitter will leave your car stuck in place, with no controls being given.

  6. 6

    Fill your car with RC fuel before any races to ensure you do not run out in the middle of the race.
