EVO 2 hard white inline motor mount

The NSR hard white inline motor mount EVO 2: precision and rigidity for the Mosler Evo 3

The reference NSR1243 corresponds to the motor mount in inline configuration (longitudinal motor, in line with the rear axle) in the hard white version from NSR, designed for the Mosler Evo 3 chassis. In inline motorisation, the motor is positioned perpendicular to the rear axle, aligned with the longitudinal axis of the car, which helps lower the centre of gravity and distribute weight more evenly.

Main features

• Inline configuration: motor arranged in line with the rear axle for a low and centred weight profile.
• Hard white version: the material in its hard variant offers greater structural rigidity, reducing flex in the motor assembly under load.
• Specific compatibility: designed for the NSR Mosler Evo 3 chassis.
• NSR reference: 1243.

Function and performance

The motor mount is one of the most critical components of the drivetrain in a competitive slot car. Its rigidity directly affects the power transmission to the rear axle: a mount with excessive flex introduces alignment losses between pinion and crown gear, leading to premature wear and efficiency losses. The hard version from NSR is aimed at drivers who prioritise consistency and direct transmission, especially on technical tracks or in categories where time homogeneity is key.

Compatibilities

This mount is specifically designed for the NSR Mosler Evo 3 chassis. Before installing it on another NSR chassis, we recommend checking compatibility with the specific model, as NSR offers various mount variants depending on the chassis platform.

Assembly and preparation

Installing an inline motor mount requires attention to the alignment between pinion and crown gear. It is advisable to ensure that the mount is perfectly seated in the chassis before tightening it definitively, checking for any lateral play. Once installed, a small run-in without load allows verification that the transmission rotates without vibrations or tight spots.

Frequently asked questions

What is the difference between the hard version and other versions of the EVO 2 mount?

NSR offers its mounts in different material hardnesses. The hard version provides greater rigidity, favouring direct transmission and reducing flex under load. Softer versions allow for some vibration absorption but may introduce alignment variations under demanding conditions.

Is this mount compatible with other NSR chassis besides the Mosler Evo 3?

The reference NSR1243 is specified for the Mosler Evo 3 chassis. Although some NSR mounts share geometry across platforms, we recommend confirming exact compatibility before using it on another chassis model.

What does inline configuration mean in a slot car?

In inline configuration, the motor is placed longitudinally, perpendicular to the rear axle, aligned with the car's axis. This reduces the centre of gravity compared to other configurations and favours a more balanced weight distribution.

Can I use this mount in combination with any NSR motor?

The mount is designed for motors compatible with the Mosler Evo 3 platform. Specific compatibility with each motor reference depends on the size of the motor casing (shark type, king, etc.). Please consult NSR's technical documentation or ask us if you have questions about the combination.

Does the hardness of the mount affect cornering behaviour?

Yes. A stiffer mount transmits power changes more directly, which can be noticeable in the car's response in fast corners. Some drivers prefer the hard version for circuits with few slow corners, where consistency in transmission is a priority.

The NSR1243 is a hard inline motor mount EVO 2, specifically designed for the NSR Mosler Evo 3 chassis. Ideal for slot car racing enthusiasts seeking rigid motor alignment and consistent power transfer on the rear axle. A key upgrade part for competitive 1:32 slot racing, compatible with NSR Mosler Evo 3 platforms.
