RC Car Radio Transmitter and Other Electronics in your Toy

Radio-controlled cars are amongst the most popular products when talking about toys for the big boys. They are fun to play with, but they can also be complicated, especially for beginners who have no adept technical knowledge. It is important to carefully follow instructions in their use and to know each part, as well as how to troubleshoot them when a problem arises. Its parts, like the RC car radio transmitter, can be too technical for some people, but this should not be an excuse for you to be not knowledgeable about it, especially if you are serious about your RC cars.

In the rest of this post, we will have a quick look at some of the most important parts of an RC car, including how they function. Each part is an important component of the whole, which is why it is vital to make sure that they are all working at their best.

RC Car Radio Transmitter

RC Car Radio Transmitter

This is one of the most important components of the entire system and can be highly influential of the functionality of the RC car. It makes use of radio signals that you can remotely control in order to steer the car and to direct its movement. It follows whatever commands you input and in turn, it sends these commands to the motor and the servos. This can be considered as the steering wheel of your RC car.

If you are looking for a transmitter or your RC electronics, you will be overwhelmed with the choices that are available, making it challenging to decide which one to pick. Some could even be priced as low as $30. The high-end ones, on the other hand, can be as expensive as $3,000. They are feature-rich and technically meant for those with more experience in RC cars.

There are several things that should be taken into consideration when it comes to a transmitter. Among others, one of the most important would be its ease of use. The controls should be easy to operate, especially if you are just starting to discover the wonderful world of RC. It should also have long-lasting batteries, which will allow you to use it longer. Consider as well the distance range that it can cover.

Receiver

This is the part that is located in the car. It consists of an antenna and a circuit board. The signal that is sent by the transmitter will be directed to the receiver. This will activate the command based on what has been inputted in the controls or the transmitter.

The antenna, which receives the signal from the transmitter, can often experience several problems. The issue can be evident when the car is not following the commands that are inputted through the remote control. For instance, if you steer to the right and if the car does not move, one of the first things that should be looked at would be the antenna. It can be burnt, twisted, or broken. Before opening the car and complicating things, an inspection of the antenna is one of the most basic things that can be done in troubleshooting your RC car.

In some instances, however, the RC car may not have an antenna as part of the receiver. This is especially true in the case of more modern and higher-end alternatives. Rather than the usual exposed antenna, they make use of infrared signals.

Servos

Available in a variety of shapes and sizes, they are the ones that are basically responsible for moving the control surfaces. More often than not, their weight is used in order to have them classified. They are directly connected to the receiver, and hence, the functionality of the two will be interdependent with each other.

Generally speaking, there are three different sizes. They can be micro, standard, or giant. The size of the car will often be an indication of the size of the servo that is appropriate to be used. Aside from their size, they can also be rated based on their speed and their torque. Torque ratings will refer to the maximum amount of the rotational force that can be produced. Speed, on the other hand, will measure the time that will be needed by the servo to turn at a specific degree.

Electronic Speed Controller

Also known as motor controller, it will be the one responsible for controlling the speed of the motor depending on the commands that have been sent by the transmitter. It is plugged to the main battery of the RC car.

Generally, the electronic speed controller can be categorized into two: brushless and brushed. The simpler and cheaper option is the brushed controller but takes note that they are only suitable with brushed motor. The brushless controller, on the other hand, can deliver more advanced functionalities for your RC car.
