Triangular cradle in yellow extralight line

NSR Triangular Cradle for Inline Motor: Lightness and Precision Where It Matters Most

The reference NSR1250 is the triangular inline cradle in yellow from NSR's extralight series. In the world of competitive slot racing, weight is a factor that makes a real difference on the track, and NSR knows this better than anyone: this part is part of their range of preparation components designed to optimise every gram of the assembly.

Function and Performance

The cradle is the support that secures the motor to the chassis and determines its position relative to the rear axle. In the inline configuration, the motor is placed longitudinally — in line with the rear axle and perpendicular to it — which allows for a lower centre of gravity for the vehicle and improves stability in fast corners. The triangular geometry of this cradle contributes to a firm and snug fit, a key factor for transmitting the motor's power without losses or unwanted vibrations.

Its finish in the extralight version is aimed at those looking to minimise the total weight of the drivetrain without compromising the structural integrity of the assembly. The yellow colour also facilitates quick identification of the component during pit stops or car preparation.

Compatibility

This cradle is designed within the NSR component ecosystem, so it fits natively with the brand's chassis and motors intended for inline configuration. To confirm the exact compatibility with your specific motor or chassis, we recommend consulting NSR's technical documentation or contacting us directly.

Assembly and Preparation

• Check the alignment of the motor relative to the axle before tightening it definitively: any deviation will affect traction behaviour.
• Ensure that the crown gear and pinion have the correct clearance after installing the cradle; the axle distance adjustment partly depends on the motor's position.
• As an extralight part, avoid excessive tightening that could deform the material and compromise the fit.

Ideal for…

This cradle is aimed at club racers and competitors who prepare their slot cars with technical criteria and who already understand the advantages of the inline configuration for certain tracks and categories. It is also useful for those who rebuild or modify NSR chassis looking for controlled weight reduction.

Considerations

Before acquiring this component, ensure that your chassis accepts a triangular cradle and that the motor you are going to mount is compatible with the inline position. NSR offers a wide range of cradles with different geometries and hardnesses, so choosing the correct reference is as important as the motor itself.

Frequently Asked Questions

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

In the inline configuration, the motor is placed longitudinally relative to the chassis, in line with the rear axle. In the sidewinder, the motor is positioned transversely, parallel to the axle. Each offers a different behaviour on track and is compatible with different transmissions.

Is the extralight version less durable than the standard?

Not necessarily. The extralight version is manufactured to provide sufficient durability under competitive conditions, simply optimising the material to reduce weight. With correct assembly and without excessive tightening, its durability is fully adequate for regular club use.

What is the purpose of the cradle's colour?

The colour in NSR cradles is not decorative: it serves to visually identify the type or hardness of the component quickly during preparation. In this case, the yellow colour corresponds to the extralight version of the triangular inline range.

Can I use this cradle with motors from other brands?

The cradle is designed within the NSR system. Before using it with motors from other brands, check the motor dimensions and compatibility with the chassis. If you have any doubts, consult us and we will help you find the correct combination.

Do I need special tools to install this cradle?

The assembly does not require special tools, although having a good caliper and the usual axle distance adjustment tools in slot preparation facilitates precise and quick assembly.

The NSR1250 is a triangular inline motor mount in the extralight yellow version, designed for slot car preparation and competition use. As part of NSR's lightweight component range, it offers a precise fit for inline motor configurations, helping reduce the overall weight of the drivetrain without sacrificing structural integrity. A key choice for club racers and slot car builders looking to fine-tune their NSR chassis setup.
