RC Car Racing – The Basics
For a beginner, the sheer amount of brands, varieties and specs of RC vehicles can be overwhelming. There are literally hundreds of types of RC cars and trucks, all with different engines, performance levels and completely customizable details. This puts hobby quality RC cars on a whole different level than toys and replicas, and is what makes them so much more interesting and exciting to play with.
While the actual mechanics of how each RC vehicle works can vary greatly from one to the next, the basic principles remain the same. Once you understand how RC cars work, you’ll have a better idea of just what’s involved, and which one would be right for you.
There are four main parts to an RC vehicle:
• Transmitter: This is the control you hold in your hand, usually powered by a 9-volt battery. Using radio frequencies, the transmitter relays the steering and control commands you give it to the receiver.
• Receiver: There are two parts to the receiver- an antenna and a circuit board inside the car. The radio frequencies sent by the transmitter are picked up by the receiver and relayed to the various appropriate parts of the vehicle.
• Motor(s): RC cars and trucks feature a variety of different types of engines, all with varying degrees of difficulty and output. The motor is often said to be the heart of the RC car and is the most intricate part of building your own RC.
• Power Source: Of course power is needed for acceleration, steering and overall engine output. Aside from the 9-volt battery in the transmitter, the power source depends on the type of car: electric cars run on rechargeable, replaceable battery pack while nitro cars use a fuel mixture similar to what runs a real car.
What does RC Stand For?
If you’re new to RC it can often be confusing just what is meant- radio or remote control cars. Though the two are often used interchangeably, this is incorrect; they are not the same thing at all, since the way they transmit signals is completely different. You can spot a remote control car by the wire connecting the controller to the car itself. Radio control vehicles, on the other hand, use radio frequencies to send messages from the steering controls on the transmitter to the receiver in the car.
There are FCC regulations for all consumer electronics that use radio frequencies, in order to properly allocate the frequencies on the band without too much interference. Usually RC vehicles operate at 27MHz or 49MHz frequencies- the same as your walkie talkie or garage door opener. More advanced RC models like planes require a higher frequency, and are regulated to 72MHz or 75MHz. Always consult your manual to make sure you’re using the correct frequency, and for instructions on how to change frequency.
As long as you’re running your RC by yourself, all you need to do is follow the manufacturer’s instructions on how to choose the correct frequency for your vehicle. But when it comes to race time or even just practicing with friends, you’ll need to make sure every one has their own frequency or the signals will get crossed. If you’re at an official race, the organizers take care of this by providing each racer with a specific frequency and a flag with which to mark your car. In order to avoid crossed signals, you’ll need to make sure when practicing that you follow a similar process.
If you are thinking of what particular remote control helicopter to buy, then this article should help.
Here are the different types of remote control helicopter:
Gas remote control helicopter – If you are thinking of flying a helicopter that somehow close to flying a real helicopter, then the gas remote control helicopter is for you. Made with an engine and powered by gas, this helicopter is the most advanced remote control helicopter to buy. Gas remote control helicopter does not come cheap with engine and more complicated moving parts. Gas remote control helicopter is for advanced rc pilot.
Electric remote control helicopter – Early electric remote control helicopters released are expensive but later models are more affordable. This makes electric remote control helicopters more popular than any type of remote control helicopters in the market. It is easy to fly. It creates no noise and smell not like the gas remote control helicopter. It is powered by a rechargeable battery. The electric remote control helicopter is suitable for beginners.
Mini remote control helicopter – Also powered by battery, this type of remote control helicopter is similar to the electric rc helicopter. In fact, it is hard to define if the electric remote control helicopter falls on the category of a mini. But to be safe about it, you can say that it is mini if you can fly it on your living room without imposing danger on your furniture.
Mini remote control helicopter is fun to fly although controlling it on air might be a little complicated at first. But once you get the hang of it, maneuvers and landings are easy. It is also far more affordable than the two mentioned types of remote control helicopter.
Micro remote control helicopter – If you have seen micro rc car, micro rc boat, and micro rc plane, then you should not be surprised if you see micro remote control helicopter. This tiny piece of aircraft can stretch up to 8 inches. But, you cannot consider it a toy. It has standard features similar to that of a standard remote control helicopter. It is so tiny that makes it look so delicate but in face, materials used such as titanium and carbon is strong.
Toy remote control helicopter – If you want an affordable remote control helicopter, then this one is for you. Only remember that to fly this type of remote control helicopter requires a lot of practice.
