Zero Chassis

The Zero Chasssis (Japanese: ゼロシャーシ, Zero Shāshi) is a Mini 4WD chassis released by Tamiya in September 1990 with the release of Dash-0 Horizon.

General info

The chassis has lower center of gravity due to its lower height, and it is lighter compared to other chassis at the time. The side-guard has now become optional (through tune-up parts), the gear cover was now attaches to motor case instead of the main chassis, and has the hard-point for the rear stay for further tuning.

Unfortunately, it suffers one problem: due to massive weight reduction, the chassis structure is weak and its front bumper, as a result, could break easily. Tamiya would release the FRP front bumper plates to fix this problem.

The design was later reused on Super-1 Chassis.

  • It is the first chassis to be equipped with the 1.4 mm propeller shaft.
    • It is also the first chassis to have the newly designed, pink-colored helical crown gears.
  • Oddly, the Dash-0 Horizon bodyshell was originally designed for Type-3 Chassis, but for some reason Tamiya switched to Zero Chassis. This results in some inconsistant gap between the body and chassis.
  • Earlier Zero Chassis car batches has the A parts molded in different color (light warm gray) than the main chassis frame. This practice was dropped in later batches.
