Radio Systems for Controlling Your Car

RC cars are controlled using a radio system that includes a transmitter and receiver. This allows input from the transmitter in your hands to be sent to the receiver in the car up to distances of 1 km or more.

Here are key features to look for in hobby-grade radios:

  • 2.4GHz Spread Spectrum – This modern radio technology hops frequencies for excellent resistance to interference. Replaces older 27/75 MHz systems.
  • Number of Channels – The more channels, the more functions can be controlled. Look for at least 2 (steering and throttle) but 4+ is ideal for advanced models.
  • Adjustability – High end systems allow you to dial in settings like throttle and brake curves for personalized feel.
  • Model Memory – Allows you to save programming for different vehicles and easily switch between them.
  • Range – Maximum distance the transmitter and receiver can communicate. 100-300 meters is common but longer 1km+ ranges are possible. Consider a long range RC transmitter for maximum coverage.

While toy-grade RCs come with very basic radios, buying a hobby-grade radio system separately can provide better range, settings, and long term durability. Popular options are made by hobby leaders like Futaba, Spektrum, Tactic and more.

LiPo Batteries – Powering Electric RC Cars

Rechargeable Lithium Polymer (LiPo) batteries have become the standard for powering fast electric RC cars and trucks. Here is an overview of LiPo technology:
