What are Radio Controlled Cars ( RC cars ) - Part 2
Something to keep in mind from the outset is that RC vehicles are a high-end hobby, and can get quite expensive. If you plan to race your car, there are additional costs that come with competition. But if you’re prepared for the cost, and if you make your purchases carefully, you’ll be rewarded with an amazing new hobby whose rewards certainly outweigh the cost. These are the decisions that need to be made before you buy:
* Do you want a ready to run RC car or do you want build your own?
* Do you want an on-road or an off-road RC vehicle?
* Which is right for you- a nitro or an electric RC?
* What type of RC vehicle do you want- and what size?
No matter what you decide, if you keep your own experience and commitment level in mind, you’ll be certain to get the car that’s right for you.
What does the RC in RC cars 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 with your RC vehicle that you follow a similar process.
