1/24 Slot Cars
In 1/24 slot cars 1 unit of length of the model equals 24 units of the actual size of the car. So, if a real car is 180 inches in length, its 1/24 model would be 7.5 inches long.
Such a big sized model requires a lot of space on its running track to operate, hence it is not fit for home settings and is used in clubs and parks only.
