AFX car (the orange Javelin) and a Herpa HO model car. (Yellow '69 Mustang)

The AFX  car is 1/64th scale, true HO scale is 1/87th scale which is exemplified with the Mustang. Many people misnomer these Slot Cars and refer to it as HO racing, but it's really 1/64th scale racing.

    While I'd love to see high detailed 1/87th cars that run like tjets, making a solid easy to work on chassis that small would be quite challenging.
