The Fox chassis is a one off, meaning there were no second model using the same chassis. There are not many of those in the Tamiya range. The front and rear suspension is a double wishbone system with a mono-shock in the front and two shocks in the rear. The radio box is an enclosed type and the battery is mounted from the underside. In 20143 Tamiya re-released the Fox as the Novafox. The modifications to the chassis were minor.
