Soft blue short box sidewinder cradle

The NSR1246 sidewinder cradle: small part, big impact on tuning

In the world of competitive slot racing, details make the difference between reaching the podium or finishing just tenths behind. The soft blue short box sidewinder cradle (NSR1246) is one of those components that, despite its modest appearance, directly influences how the motor operates and how the car responds in every corner.

Function and performance

The cradle is the element that houses and secures the motor within the chassis, determining its position, fixing rigidity, and consequently, the power transmission to the rear axle. In sidewinder configuration, the motor is placed parallel to the rear axle, allowing for a more central mass distribution and direct, efficient transmission.

• Soft hardness (blue): offers greater vibration absorption and a more flexible motor hold, which can translate into smoother and more progressive driving, especially on technical tracks with many curves.
• Short box: designed for NSR chassis that require the shorter version, optimizing internal space and the centre of gravity of the assembly.
• Manufactured to the usual precision standards of NSR, ensuring a correct and repeatable fit in every assembly.

Compatibility

This cradle is designed for NSR chassis compatible with the short box sidewinder configuration. NSR offers one of the most comprehensive and organized ranges of spare parts in the slot market, with different hardnesses and versions so that each driver can find the configuration that best suits their driving style and track type.

Check compatibility with your specific model before placing an order, as NSR has variants for different chassis in its catalogue.

Assembly and preparation

The assembly of the cradle does not require special tools, but attention to adjustment is necessary: a poorly fitted cradle can create play in the motor that negatively affects performance and transmission durability. We recommend checking the condition of the braids and guide whenever working in the motor area.

For enthusiasts competing in clubs or meticulously preparing their cars, having cradles of different hardnesses allows for configuration comparisons and choosing the one that works best on each circuit.

Ideal for…

• Club drivers who adjust their car for each training session or race.
• Preparers looking to explore the effect of cradle hardness on chassis behaviour.
• Enthusiasts who maintain a stock of NSR spare parts for quick interventions in competition.

Aspects to consider

The difference between a soft and a hard cradle is not trivial: the soft version (blue) absorbs track irregularities more and softens the motor's work, while a stiffer cradle transmits power more directly. The choice depends on driving style, track type, and the power of the motor used.

Frequently asked questions

What does it mean for the cradle to be "soft" (blue)?

The blue colour identifies the soft hardness within NSR's coding system. A soft cradle offers greater flexibility and vibration absorption in motor holding, which can improve progressiveness and stability on technical tracks.

What is the difference between short box and long box?

The length of the cradle determines its compatibility with different NSR chassis. The short box version is designed for chassis with less space in the motor area. It is essential to choose the correct version to ensure a precise fit.

Can this cradle be used with motors from other brands?

The cradle is optimized for NSR motors, although in some cases it may be compatible with motors of similar dimensions. We recommend checking the measurements before using it with motors from other brands.

How often should the cradle be checked or replaced?

It depends on usage and competition intensity. In frequent club sessions, it is advisable to periodically check the condition of the cradle to detect deformations or play that may affect the performance of the assembly.

Does the hardness of the cradle affect braid consumption?

Indirectly yes: a cradle in poor condition or with play can cause micromovements of the motor that affect the pressure and wear of the braids. Keeping the cradle in good condition contributes to a longer lifespan of the entire transmission system.
