A Beginner’s Guide: How RC Cars Actually Work

Driving wholesale RC cars is a little like playing video games—only better. You can master reaction time and coordination skills while seeing your efforts play out on real terrain. Every move on the controller results in lightning speeds or epic turns—or disastrous crashes.

The fun of wholesale radio control cars goes beyond driving. There’s a whole community of RC car enthusiasts with whom you can connect. And learning about the ins and outs of how RC cars actually work adds to the fun.

 

Radio Waves Make RC Cars Go Around

It all starts with a wave, and we do mean radio waves. A form of electromagnetic radiation, radio waves are made of the same stuff as visible light. Electromagnetic radiation travels much like waves on water. Only with radio waves, the crests of the waves are farther apart, which is why we can’t see them.

Even though we can’t see them, radio waves are used in many of the common devices we use, from microwave ovens to cell phones. In wholesale RC cars, radio waves carry instructions from the controller, also known as the transmitter, to a receiver installed in the car.

 

Understanding Wholesale RC Car Specs

All wholesale RC cars work in basically the same way. However, once you start shopping for an RC car, you’ll see that specifications can vary. Understanding what all those numbers mean will help you buy the right RC car for you.

 

Choosing the Right Frequency

Radio frequencies are measured in Hertz. According to TechTarget, hertz is a measurement of the number of radio waves per second.

Low-quality RC cars operate at a radio frequency of 24 megahertz (MHz). At such a low frequency, these cars are prone to interference.

High-quality cars, on the other hand, operate at a much faster frequency of 2.4 gigahertz (GHz). At this frequency, wholesale RC cars are less likely to run into interference. That means you can get your friends together for a race without worrying about any of the controllers jamming the other vehicles’ receivers.

 

Wholesale RC Cars Motors

Most wholesale radio control cars come with either a brushed motor or a brushless motor.  

Brushed motors have coils winding around an iron core. On the iron core are “brushes.” In brushed motors, the brushes carry the power to the windings. In brushless motors, on the other hand, power is carried electronically through magnetism.

Brushless motors have several advantages over brushed motors. Brushless motors are more efficient and longer lasting. They also have more power and offer higher speeds.

Brushless motors have Kv ratings, which measure the motor’s velocity. Essentially, Kv stands for the revolutions per minute per volt. For example, a motor with 3,300 Kv would have an RPM of 3,300 for every volt it receives.

The higher the Kv rating, the faster your RC car will go. However, a motor with a high Kv rating will have a lower torque capacity. Bulkier, heavier RC cars need more torque to move, which is why larger RC vehicles have motors with a lower Kv rating.

 

Understanding RC Car Batteries

Most wholesale RC cars use a lithium battery in the car battery. The size of the battery will be listed at volts and milliamp hours.

Generally speaking, the higher the volts, the faster the car can go. But that doesn’t mean you can just switch out your RC car’s battery for a bigger one. If the voltage on the battery exceeds the motor's capacity, you’ll burn out the motor.

Milliamps indicate the length of time the battery will last. For example, a battery with 5,000mAh equals 5 amp hours. If five amps drain the battery, it will last one hour. If 10 amps drain it, it will last a half hour, and so on.

 

 

Buy Wholesale RC Cars from TVCMALL

Driving wholesale remote control cars is an exciting and popular hobby. You can easily find fellow enthusiasts who share your passion and participate in events in your community. Whether you race other hobbyists or just drive your RC car in your neighborhood, knowing how RC cars work is important.

Wholesale RC cars use invisible radio waves to transmit information from the transmitter to the receiver in the car. From there, the battery powers the motor, and the receiver sends information to the car’s components.

You’ll need to make sure your new RC car has the right specifications if you’re going to THRIVE in your new hobby. Cars that operate on a frequency of 2.4 GHz have a farther reach with less interference. And a long-lasting brushless motor will allow your car to go fast. Finally, the right batter will prevent your motor from burning out. You can find quality wholesale RC cars with these specs and more at TVCMALL.
