RC cars are a fun hobby, but they come with their share of problems and issues, among them the transmitters which may occasionally not work properly. There are ways to logical and safe to check a transmitter, however, so before going out to buy a new drive, run a couple of simple tests. In doing so, try to keep away from other electrical things, such as power lines so that there is no interference.
