Why are there only two frequencies for remote control cars?
I bought three remote control cars, one for me and one for each of my two boys. But I ended up taking mine back because it had the same frequency as one of my boys and we couldnt use both of them at the same time. Upon checking the store for a third frequency vehicle I found that they were all either one or the other.
There are only a small set of "public" frequencies that can be used for all wireless devices including remote control vehicles, telephones, wireless networks, and other equipment. These public domain frequencies must all coexist in the same environments, so you will generally find that one device uses one set of frequencies while other devices uses a slightly different set.
It is quite common to see some completely different devices using the same frequencies because the manfucaturer didn't really have much of a choice. This directly limits the frequencies that any particular product can use.
You might look for some wireless devices that use similiar frequencies but have different channels. I doubt you'll find remote control vehicles that use different channels, but you might. They'd probably cost more though because they'd need more electronics inside to let you select which channel each one was on.

If they used any more frequencies it would interfere with other things such as telephones or radios.

i saw a rc helicopter with eight frequencys. if you buy the expensive cars they come in more. the hobby shop down the street has races with about 7 or 8 cars at a time. so there has to be more.

It depends on the price and brand.Some come with more and if there were to many of them it would interfere with outh things like scanners and tvs

I just bought three vehicles myself. One of them says 27 another says 49 and the last one says 27.095 on channel B. What does that mean? I haven't had a chance to try it yet, but I will let you know how it works. I did see another remote control vehicle that stated it had 4 available channels to operate off of. This would allow it to race 3 other vehicles. If the last mentioned vehicle doesn't work, then I will go back and buy the multi channel vehicle. I will let you know how I make out!
