Of course everyone worries about the frequency that they are one so that they all can race at the same time, but is that as far as it goes with r/c cars? I have been flying r/c planes for 3 years and just bought my first nitro r/c car. It seems like these are so common it would be hard to enforce frequency control because lots of people just drive them around their house. At my r/c plane club we have strict frequency rules. Our field is near a BMX track where some people drive cars. Some people are stupid enough to put aircraft radios in their cars and end of shooting a $2000 model out of the sky, and the pilot has no idea where it came from. If people would stick to ground radios in their cars there would be no problem. Do r/c car clubs or tracks make use of frequency boards or anything similar?
