Remote control cars, like rock crawlers, have become popular, and with good reason. From kids to adults, everyone has or wants an RC vehicle. In this article, I tell you everything you need to know about your RC rock crawler controller.
Why? The thrill of driving at high speed through different terrains is simply unsurpassed. However, to do this, you need to know how to use your RC rock crawler controller.
The controller is the link between the driver and the car, so every command you make, you must make using the controller. Therefore, if you want to turn left, you will turn your controller’s wheel or joystick to the left.
Further, the controller transmits radio signals to the RC rock crawler, allowing you to control its movement. For this reason, it is vital to understand how it works.
Here we go!
What is an RC Rock Crawler Controller?
This is a device that you purchase with your RC car, and it helps you control your RC rock crawler. It translates your commands, sends them to the vehicle, and the car behaves accordingly.
For instance, when you want to accelerate, you will press the appropriate button on the controller, and the controller will send a signal to the RC car, and it will start accelerating. This is the case with every command you make.
Components of an RC Rock Crawler Controller
RC controllers have a few parts that allow you to drive the vehicle conveniently. These components are:
- Wheel or joystick: they work as the steering wheel
- Switches: for extra features like shifting modes and taking photos
- Throttle: used for speed and acceleration
- Trim buttons: modifies throttle and steering response
- Antenna: receives and sends signals between the controller and RC rock crawler
How RC Rock Crawler Controllers Work
As pointed out, RC controllers significantly affect how your RC car operates. They are vital since they help you control your RC car.
So how does this happen? Here is a brief explanation of how RC controllers work:
The controller input is a vital part of your controller’s operations. When you press any button on your controller, be it the joystick or throttle, you will send a signal to the transmitter.
The transmitter then turns the input from the controller into a digital signal, which is decoded to a carrier frequency.
The decoded signal is sent to your RC rock crawler through the antenna on the controller. Typically, the transmitter’s range is based on several factors, including the controller’s power, interference in your area, and the frequency at which the transmitter operates.
The moment the signal is sent, it’s sensed by the antenna on your rock crawler. Then, your rock crawler’s receiver decodes the signal and, once more, turns it into a digital signal.
The final step of this easy-to-understand process occurs when the digital signal is transmitted to the motor, which deciphers it into a physical reaction like acceleration or turning.
Advanced Features of an RC Car Controller
The market offers plenty regarding RC rock crawler controllers, but I recommend the more feature-filled high-end options. While you can find something that works, even on a budget, the expensive options have more to offer than their counterparts.
Most advanced controllers usually have profiles that allow you to bind them to several RC rock crawlers simultaneously. This is incredibly convenient when you want to head out with two or more cars and don’t want the burden of hauling several controllers along with their batteries.
Again, on the advanced models, you will appreciate the USB port, which is perfect for updating firmware. Besides, some models have GT3B, which lets you use your controller like a PC controller.
So, what exactly does this do? It lets you learn how to drive with your controller in a virtual space. This way, you can practice as often as you’d like, and your RC car won’t be at risk of getting damaged.
RC Rock Crawler Fail-Safe
This affects the receiver more than the transmitter. Most controllers feature a fail-safe mode. Therefore, in the event that the link between the receiver and transmitter is severed, the receiver will revert all signals to the servo and ESC to neutral. This will successfully stop your RC car from moving further.
You can test your RC car fail-safe by positioning it wheels-up and then accelerating it to allow the wheels to spin before switching it off while still pressing the throttle on the controller.
What Is An RC Rock Crawler Receiver & Transmitter?
The transmitter is the gadget that transmits control signals from the controller to the car. On the other hand, the receiver receives these signals and deciphers them into physical actions for your RC rock crawler.
How Many Types of Receivers and Controllers Are There?
A few. Controllers and receivers are categorized according to frequency, with the most common ones being 72MHz, 5.8GHz, and 2.4 GHz. Each is unique in its own way, and the type you choose should be based on how and where you intend to use your rock crawler.
What Does Transmitter Range Mean?
This is the distance between the controller and your RC car within which the controller can send signals. Generally, the range can be anywhere from 100 feet to a few miles, based on your controller’s features and the conditions of your driving area.
What Occurs If the Controller and Receiver Communication is Interrupted?
If the controller’s and receiver’s communication is cut short, your RC rock crawler will stop responding to your commands. This will continue until the communication link is re-established.
It’s important to understand the basics of your RC rock crawler’s controller since, as the name suggests, it controls your car. Ensure you know the components and follow safety precautions to operate your RC car efficiently.
Additionally, it would help if you cleaned it often, along with your rock crawler, for optimal performance.
