Formula 90-97 Chassis - Medium

A specific chassis for 1990s formula single-seaters

The SC-6670B is the Medium size chassis from the Formula 90-97 line by Scaleauto, designed for those who build, prepare or restore single-seaters from the golden era of Formula 1 and formula categories of the 1990s. The designation "90-97" refers to the time frame of the cars it is intended for, a period characterised by narrow body shapes, pronounced sidepods, and proportions very different from those of current single-seaters.

Main functions and features

The chassis is the backbone of any slot car. It defines the geometry of the drivetrain, the position of the motor, the height of the centre of gravity, and the structural rigidity of the assembly. Scaleauto designs its chassis with tight tolerances to ensure that the components —motor, rear axle, guide, braids— fit precisely and without unnecessary play.

• Medium size: intermediate dimensions within the Formula 90-97 range, suitable for the body shapes of single-seaters from this period that require specific wheelbase or width measurements.
• Sport track-oriented design: compatible with the Sport track system used by Scaleauto and Slot.it, although it can also be adapted to other systems with the appropriate accessories.
• Base for construction and preparation: ideal for both scratch-building projects and for renewing a worn or damaged chassis in an existing car.

Compatibility and assembly

This chassis is part of the Scaleauto component ecosystem, so it is designed to work in combination with the motors, axles, gears, pinions, and guides of the same brand. Before purchasing, it is advisable to verify that the Medium size corresponds with the measurements of the body you will be using, as Scaleauto's Formula 90-97 range offers various sizes to accommodate different body proportions.

Who is it intended for?

This chassis is of particular interest to three types of enthusiasts:

• The kit builder: who starts with an empty body and seeks a reference chassis on which to mount all the components.
• The club preparer: who wants to replace a worn or damaged chassis while maintaining the original geometry of the car.
• The active collector: who keeps their 1990s models in running condition and needs specific spare parts for that era of single-seaters.

Considerations

Before placing an order, confirm that the Medium size (SC-6670B) is the correct one for your project. Scaleauto has other references within the same Formula 90-97 line in different sizes. A chassis with incorrect measurements may cause fitting issues with the body or with the internal components.

Frequently asked questions

What does "Medium size" mean for this chassis?

It indicates that the dimensions of the chassis —wheelbase, width— are intermediate within the Scaleauto Formula 90-97 range. There are other sizes for smaller or larger bodies within the same line.

Is it compatible with Scalextric or Ninco track?

The chassis itself is a mechanical structure, but the components mounted on it (guide, braids) determine compatibility with the track. Scaleauto's reference system is the Sport track. To use it on universal track (Scalextric, Ninco), the corresponding guide would need to be adapted.

Does it include motor, axle or guide?

No: the SC-6670B is exclusively the chassis. Other components (motor, rear axle, crown gear, pinion, guide, braids) must be purchased separately from the Scaleauto catalogue.

What type of motorisation is it compatible with?

The type of motorisation (inline, sidewinder or anglewinder) depends on the specific configuration of the chassis. Consult the technical documentation from Scaleauto for the SC-6670B or contact us to confirm the motor layout before assembly.

Can I use this chassis with bodies from other brands?

In principle, yes, as long as the measurements of the body match those of the chassis in Medium size. It is common in the hobby to combine chassis and bodies from different manufacturers, but it requires verifying dimensional compatibility before assembly.

The Scaleauto SC-6670B Formula 90-97 Medium chassis is a slot car component designed for 1990s Formula 1 and open-wheel racing car bodies. Part of Scaleauto's dedicated Formula chassis range, it offers precise geometry for Sport-system track layouts and is compatible with the brand's full range of motors, axles, gears and guide blades. An essential reference for scratch builders, club racers and collectors restoring or building classic single-seater slot cars.
