How Does An RC Car Work?

Early on in my exploration of amateur radio, I purchased a NooElec NESDR Nano 3, an SDR or Software Defined Radio USB dongle. With the SDR# application, and the rubber ducky antenna that came with my Baofeng handheld transceiver, we are able to monitor a wide variety of radio frequency transmissions. This includes FM Radio, Weather channels, amateur radio, and yes, RC cars! Today, Jordan and I learned how the remote for an RC car tells the cars when to go left, right, backwards and forwards.
