Soft blue inline Formula 1 motor mount

Precision from the chassis: NSR's inline mount for Formula 1 in soft version

When we talk about serious preparation in slot racing, every component matters. The NSR1280 is the motor mount in inline configuration designed by NSR specifically for their Formula 1 chassis, available in the soft version identified in blue. An apparently small piece that has a direct and measurable impact on the car's behaviour on the track.

Function and performance

The motor mount is the element that anchors the motor to the chassis and determines its position relative to the rear axle. In inline configuration, the motor is oriented longitudinally — perpendicular to the rear axle — which helps to lower the centre of gravity of the assembly and improve traction during acceleration and stability in corners.

The soft (blue) version offers greater absorption of vibrations transmitted from the motor to the chassis, resulting in smoother driving and less loss of grip on technical circuits or uneven surfaces. It is the usual choice of tuners looking for a more docile and predictable car, especially in configurations with high-revving motors.

Compatibility

This mount is designed for NSR Formula 1 chassis that accept inline configuration. Before installation, it is advisable to check that the chassis in question accepts this type of mount and that the chosen hardness (soft/blue) is suitable for the motor and the circuit where it will compete.

Installation and preparation

The installation is straightforward for someone with basic slot preparation experience. However, it is important to consider some aspects to get the most out of it:

• Ensure that the mount is perfectly seated and without play before tightening.
• Check the alignment of the motor with the rear axle once installed: any deviation directly affects the performance of the transmission.
• Combine the hardness of the mount with that of the other elastic elements of the chassis (springs, rubbers) to achieve a coherent setup.

Soft or hard? The importance of choosing the right hardness

NSR offers mounts in different hardnesses, usually identified by colour. The soft (blue) version better absorbs the irregularities of the circuit and reduces the transmission of vibrations, benefiting grip on tracks with joints or less uniform surfaces. The hard version, on the other hand, offers greater stiffness and a more direct response, being preferred on very smooth and technical circuits where precision takes precedence over comfort.

Knowing the characteristics of your usual circuit is key to choosing the correct hardness.

Frequently asked questions

What is the difference between an inline mount and a sidewinder?

In the inline configuration, the motor is placed in line with the car, longitudinally and perpendicular to the rear axle. This reduces the centre of gravity. In the sidewinder configuration, the motor is parallel to the rear axle, transversely. Each arrangement has different implications for the car's dynamic behaviour.

Which chassis is the NSR1280 compatible with?

This mount is designed for NSR Formula 1 chassis in inline configuration. We recommend checking the technical sheet of your chassis or contacting us to confirm the exact compatibility with your specific model.

When should I use the soft version instead of the hard one?

The soft version (blue) is most suitable when the circuit has uneven surfaces, pronounced joints, or when you are looking for a more stable and predictable car. If the circuit is very smooth and you seek maximum response and stiffness, a higher hardness may be preferable.

Does the hardness of the mount affect motor wear?

Indirectly, yes. A softer mount better dampens the vibrations from the motor, which can help prolong the lifespan of the bearings and the motor itself by reducing mechanical stress.

Is it sold in individual units?

This product is marketed as indicated in the specification. Check the quantity information on the product page or contact us if you have any questions.

NSR's inline motor mount for Formula 1 chassis (ref. NSR1280), soft version in blue, is an essential tuning component for slot car enthusiasts focused on performance. The inline motor configuration lowers the centre of gravity, improving traction and cornering stability. The soft durometer absorbs vibrations and enhances grip on technical or uneven tracks. Compatible with NSR Formula 1 chassis designed for inline setup. A key part for competitive slot racing builders looking to fine-tune their car's dynamic behaviour.
