Receives all commands from the Digital Controller, and Digital Control Unit. Note: Ninco chips are too large for some types of body styles such as Formula 1 and some smaller types of sports cars. Ninco does not warrant these chips if installed in cars other than Ninco. We have heard it is harder to chip SCX Analog cars; we don"t recommend them for beginners.
