What does GHz mean in RC cars?
GHz, or Gigahertz, is a measurement of frequency used to describe the speed of a radio controlled (RC) car. It is essentially the maximum rate of speed at which the car’s radio signal can communicate with its receiver. RC cars use the frequency of their radio signal to control the car’s throttle, steering and other motor functions. The higher the GHz, the faster the car can move, as well as the further it can go without interference.
In the early days of RC cars, the industry standard was 27 MHz, which was the highest frequency then available. This frequency was capable of transmitting radio signals over fairly short distances, and had a maximum speed of around 15 mph. As technology advanced, 27 MHz was replaced with 75, 40, and eventually 2.4 GHz. The 2.4 GHz frequency was the first to offer both an extended range and low-interference transmissions which allowed for more complex motor functions, and a greater variety of motor speeds.
The higher the GHz, the faster speed and further range a car is capable of. Most RC cars now run on 2.4 GHz frequency and have a maximum speed of around 30 mph. There are even cars on the market that run on 5 GHz, allowing them to reach speeds of up to 50 mph and transmit control signals over greater distances. While these cars can often cost more than their 2.4 GHz counterparts, their range and speed can be invaluable when racing competition or on larger tracks.
Most RC car manufactures today have standardized on the 2.4 GHz frequency as it offers an ideal combination of performance and range for the average RC enthusiast. Its popularity has also meant that most battery and motor upgrades can be used with either 2.4 or 5 GHz systems.
In conclusion, GHz is a measurement of frequency used to describe the speed of a radio controlled car. It measures the maximum rate of speed at which the car’s radio signal can communicate with its receiver, and higher GHz frequencies allow for faster speeds and greater range. Most RC cars today run on 2.4 GHz frequency, with models available on 5 GHz capable of speeds up to 50 mph and greater range.
