FLY EVO3 chassis Ford GT40 for RT3 Motor Mounts

Scaleauto EVO3: the chassis that the Fly Ford GT40 deserved from the start

The body of the Fly Ford GT40 is, for many enthusiasts, one of the aesthetic references of 1/32 slot racing. Its low and aggressive silhouette directly evokes the four consecutive victories at the 24 Hours of Le Mans between 1966 and 1969. However, the original mechanics significantly limit its performance on track. The SC-9100F chassis from Scaleauto is the technical answer to that imbalance: a platform from the EVO3 series specifically designed for this model, which allows for maximum utilisation of the RT3 motor mount system without sacrificing a millimetre of compatibility with the original bodywork.

Function and performance

The EVO3 chassis is not a generic adaptation: its anchor points are calculated for the Fly Ford GT40, ensuring a precise fit of the body without play or stress on the plastic. The structure is made from technical plastic with controlled flex, a material that reduces the torsional stiffness of the assembly compared to the original chassis. This translates into better transmission of torque to the rear tyres, especially in tight corners where the car tends to lift the inner axle.

The lowered geometry of the EVO3 reduces the centre of gravity compared to the standard chassis, improving stability during acceleration and braking. The result is a more predictable vehicle that is easier to adjust for different layouts.

Compatibility and assembly

This chassis is designed to work in combination with the RT3 motor mounts from Scaleauto, which allow the motor to be mounted in three different configurations according to the needs of the track:

• Inline: longitudinal motor, perpendicular to the rear axle. Further lowers the centre of gravity and favours traction on fast tracks.
• Sidewinder: transverse motor, parallel to the rear axle. Balanced configuration, very common in club racing.
• Anglewinder: motor angled relative to the rear axle. Combines characteristics of the previous two and is particularly effective on mixed circuits.

The adjustment of the front axle height is done using allen screws, allowing for millimetric regulation of the tilt without the need for specialised tools. This point is key to adapting the car's behaviour to tracks with different radii and curve profiles.

Preparation and tuning

The assembly of the SC-9100F does not require modifications to the Fly Ford GT40 body. The anchor points respect the original geometry of the model, making the replacement process straightforward. Once the chassis and RT3 mounts are installed, the enthusiast has a much greater adjustment margin than the factory configuration, allowing for independent tuning of height, flex, and motorisation.

For club competitors looking to extract the maximum from a classic body without resorting to pure competition cars, this set offers a balance between technical accessibility and performance that is hard to surpass in the 1/32 category.

Frequently asked questions

Which Fly Ford GT40 models is this chassis compatible with?

The SC-9100F is specifically designed for the Fly Ford GT40 models. We recommend checking the exact reference of your model before assembly, as there may be variations between body versions.

Is it necessary to purchase the RT3 mounts separately?

Yes. This chassis is prepared to receive the RT3 motor mounts from Scaleauto, but these mounts are not included in the pack. You will need to purchase them separately to complete the set.

What motor configuration is most recommended for club racing?

It depends on the track. The sidewinder configuration is the most versatile and the most common on mixed club circuits. The inline configuration favours traction on fast tracks with wide curves, while the anglewinder offers an interesting middle ground for technical layouts.

Does this chassis require modification of the original Fly body?

No. The anchor points of the EVO3 are designed to respect the geometry of the original body, so the assembly is direct without the need for sanding, drilling, or any other modification.

What type of track does this set work best on?

The EVO3 chassis with RT3 mounts is designed for competition tracks, both on Scaleauto rails and other compatible systems. Its adjustability makes it particularly interesting on circuits with varied curves where tilt and centre of gravity make a difference.

Can I use this chassis solely for collection or recreational use?

Yes, although its technical profile is clearly oriented towards competition and preparation. If you are looking for recreational use without adjustments, the original chassis may be sufficient. This product is intended for those who want to make real use of the GT40 body.

The Scaleauto SC-9100F EVO3 chassis is a high-performance 1/32 slot car upgrade specifically engineered for Fly Ford GT40 bodies, offering full compatibility with RT3 motor mount supports. Built from controlled-flex technical plastic, it lowers the centre of gravity and allows fine-tuning of the front axle height via allen screws. Supports inline, sidewinder and anglewinder motor configurations, making it a versatile choice for club racing and competitive slot car preparation. A precision replacement chassis for serious 1/32 slot racing enthusiasts.
