A 21.5 touring car refers to a 1/10 scale, four-wheel-drive electric radio-controlled (RC) touring car that uses a specific 21.5-turn brushless motor in sanctioned racing classes. These cars are popular in "blinky" spec racing, where the electronic speed control (ESC) is set to a non-timing (blinky) mode, making motor choice and chassis setup crucial for performance
