Type-2 Chassis

The Type-2 Chassis (タイプ2シャーシ) is the second Type Chassis released by Tamiya in December 1988 with the release of Avante Jr.

General info

The chassis is different than the Type-1 Chassis as it was designed purely for on-road track racing. Large wheels, low-profile slick tires as well as guide rollers are all standard features for this chassis.

It also introduced the use of driveshaft bearing attachments, which is the standard for all future chassis. The default plastic/brass bearings can be replaced with either the metal bearings or the ball bearings.

The motor mount and gear box has been redesigned to reduce difficulty of maintain the motor and gears. Battery clip is now standard with this chassis. There's also the holes around the chassis to dissipate heat from the motor and batteries.

The chassis was redesigned so it will have minimal power losses, which was one of the problems that plagued the Type-1 Chassis. In addition, the chassis has lower center-of-gravity as the inner parts are placed lower.

While it may be good for racing, it has few problems: The first is that most bodies designed for Type-1 Chassis are not compatible with the new chassis due to having longer wheelbase and the way how the motor is placed. Secondly, it is not compatible with some tune-up parts at the time of its release. Finally, its front bumper, much like every Type series chassis, could break easily

Performance-wise, it performs better than the Type-1, despite this it have poor acceleration performance due to its long wheelbase (which is shared with Type-4 Chassis, Super TZ Chassis and Super TZ-X Chassis)

The design of Type-2 would later updated into Type-4 Chassis.
