RC remote controls work by utilizing specific frequencies when connecting to RC toys or other devices. Those frequencies allow for the device to know what it is supposed to do when you press the remote control. Below I will discuss the different frequencies for RC devices and how everything works together. I will also discuss the differences between radio control and remote control when it comes to both toys and models.
RC technology allows us a choice for the kind of toy we can control. With RC technology, you can pick from cars, trucks, airplanes, helicopters, robots, animals, boats and many more. With so many different styles, the mechanics of how these toys operate can vary quite a bit between the various models.
When you press a button on your remote, it will send a signal out to your receiver via radio waves, which then controls the motor and creates a specific action. For example, if your RC toy is a car, then using the engine might make your wheels turn. Also, most of these RC toys feature a power source that usually comes in the form of a rechargeable battery pack, although some toys only have standard batteries.
For most RC toys, the use of the radio-controlled motor is what guides the toy, and the source of power used by the toy is what moves the toy forwards or backward. That transmitter is used to send a signal over a frequency, which then goes to the receiver on the toy. The remote has its power source, which is typically a 9-volt battery.
That battery powers the controls and helps transcribe the signal. So that leads us to the difference between radio-controlled toys and remote-controlled toys. However, with radio-controlled toys, your device would be wireless. These two frequencies are what the FCC allocates for simple consumer devices like walkie-talkies, garage door and gate openers, and RC toys. However, more advanced RC models which are also usually more expensive use MHz or Mhz frequencies.
Still, most RC toys feature labels with the rate ranges the use. For instance, most RC trucks have labels that say the toy is a MHz model. Some manufacturers of RC toys make versions of their models for both of the most popular frequency ranges, 27Mhz and 49 MHz.
By doing that, customers can use two of the same types of RC toys at the same time if they want to race each other or play together without interference. As far as transmitters go, most of them range from a single-function controller with one option to a full-function controller with a bevy of control options. A single-function controller usually makes the toy move forward when you press the button, and then the toy moves backward when you release it.
If you want to stop the toy, you need to turn it off. On the other hand, your more complex controller would be a full-function controller. Typically, a full-function controller will offer six control options: forward, reverse, forward left, forward right, reverse left, and reverse right. Many advanced RC controllers have dual joysticks as well. If you think about it, remote controls have been around for a long time.
Back in WWI, the Germans used the first set of remote controls that were radio-frequency devices that were guided to crash into Allied boats. During WWII, remote-control technology was used for the first time to detonate bombs from far away. Nowadays, we see remote-control technology all around us. Infrared light is heat or light that carries signals from the remote control to the device it is instruction.
Infrared light works as the invisible part of the electromagnetic spectrum. So, how does an IR remote control work? With an IR remote control, the transmitter kicks off the process by sending out a certain amount of infrared light that symbolized specific binary codes.

Parts of an RC toy Transmitter: The remote control contains a radio transmitter which operates on a particular frequency that the receiver is designed to receive.
The higher frequency also allows the RC vehicles to work at longer distances 30 to 80 meters. The standard 27 and 49 MHz transmitters and receivers both take special plug-in crystals that are set to communicate and work at the same frequency. But if there are ten people with RC vehicles nearby working in the 2.
The receiver and the transmitter have to be bound first for the RC vehicle to work properly. Something very similar to how certain remote control garage doors work Some RC vehicles come already bound, so you may not have to do that with every RC car.
Every time you press a button, trigger, or a switch, an electrical signal is created and sent to the RC car. When you press a specific button, this causes a specific circuit found on the circuit board to be completed a lot similar to how electrical circuits in our homes work. When the circuit is completed, it sends electrical pulses. These electrical pulses are comprised of a set of synchronization pulses, followed by the actual pulse sequence.
The synchronization pulses inform the receiver that there is incoming information then the actual pulse sequence tells the receiver what the information is. So when you pull the throttle trigger, the receiver will send a signal that contains 16 pulses.
These pulses will have the receiver send positive current through the circuit board to the motor powering it up and making the RC car go forward. All of these pulses operate in one particular MHz range.
Any other signals with different MHz are filtered out. Each function of the RC Car works on separate channels. These channels should not be confused with radio channels or radio frequencies. Rather this refers to how the separate electric components are connected.
To work properly, RC vehicles need to have at least two channels. The channels are designated and associated with the control of different aspects of the vehicles. The first channel always controls the steering. And the second channel is dedicated to speed control. If the vehicle has other accessories and features like LED lights, wench, reverse movement, and more, each one of these may need a separate channel. Electric RC Cars use an electric motor that is powered by electricity.
Usually, this is done through the use of a battery pack. The most widely used type of electric motor used for RC toys is the brushed electric motor. However, recently the brushless electric motors are becoming increasingly more popular.
Brushed vs Brushless RC Motor. The nitro RC cars have an engine that works with fuel. The fuel is usually methanol-based mixed with oil and nitromethane and hence why they are called Nitros.
