Red extraduro evo angle triangular motor support

When motor geometry makes the difference: NSR extra-hard triangular anglewinder mount

In competitive slot racing, the motor mount is not just a simple support: it is the element that defines the transmission geometry, the working angle of the crown gear with the pinion, and ultimately, the car's consistency on track. NSR knows this, which is why it offers this triangular mount for anglewinder configuration in an extra-hard version, identified in red.

Main features

• Anglewinder configuration: the motor is mounted at an angle relative to the rear axle, a solution that optimises weight distribution and the height of the centre of gravity compared to other arrangements.
• Extra-hard version (red): the colour code indicates the hardness level of the material. The extra-hard version offers maximum rigidity, minimising any flex or unwanted movement of the motor-transmission assembly under load.
• Triangular design: the triangular geometry provides a more stable and precise mounting of the motor within the chassis, reducing vibrations and maintaining a constant pinion-crown engagement.
• NSR reference: NSR1259, manufactured to the precision standards that characterise the NSR spare parts range.

Function and performance

The motor mount is one of those components that the casual enthusiast barely considers, but that the tuner or club racer knows very well. A rigid and well-aligned mount ensures that the pinion and crown always work at the same contact point, resulting in smoother transmission, less gear wear, and a more predictable response when accelerating.

The extra-hard version is designed for setups that require minimal tolerance: technical tracks with many curves where the transmission continuously receives lateral loads, or competitors looking to eliminate any variable in their car's behaviour.

Compatibility and installation

This mount is designed to fit NSR chassis compatible with the triangular anglewinder geometry. Before installation, it is advisable to verify that the chassis accommodates this type of mount and that the distance between the pinion and crown chosen is consistent with the position offered by the mount. NSR offers a wide range of crowns, pinions, and axles that allow for precise tuning of the assembly.

Usage recommendations

• Check the play between the crown and pinion after installation: it should be minimal but without rubbing.
• The extra-hard version does not require additional fixing with glue in most NSR chassis, but it is advisable to check the fit before each racing session.
• If you are looking for a more progressive behaviour or some vibration absorption, NSR also offers standard or soft hardness versions for this same mount.

Ideal for…

Tuners and club racers working with NSR chassis in anglewinder configuration who want to eliminate any variability in the transmission. Also for those building a competition car from scratch and needing the most rigid mount available to ensure that the transmission geometry remains constant throughout the race.

Frequently asked questions

What is the difference between the extra-hard (red) version and other versions of the NSR mount?

NSR colour codes the different hardness levels of its mounts. Red corresponds to the extra-hard version, which offers the highest rigidity and lowest flex. Other versions in different colours have a softer material that can better absorb track irregularities at the cost of slightly more movement in the transmission.

What exactly is anglewinder configuration?

In an anglewinder slot car, the motor is mounted at an angle relative to the rear axle, unlike the sidewinder (motor parallel to the axle, transverse) or inline (motor in line with the axle, perpendicular). The anglewinder is a compromise between both that allows for good weight distribution and maintains a compact profile.

Which NSR chassis is this mount compatible with?

It is designed for NSR chassis that accommodate triangular anglewinder mounts. We recommend checking the technical specifications of the specific chassis you use or contacting us to confirm compatibility before installation.

Do I need special tools to install this mount?

No special tools are required. Most tuners use standard slot tuning tools: precision screwdrivers and, if necessary, a caliper to check the play between the crown and pinion after installation.

Can I use this mount in a sidewinder or inline setup?

No. This mount is specifically designed for anglewinder configuration. For sidewinder or inline, NSR has specific mounts and supports for each geometry.

The NSR1259 triangular anglewinder motor mount in extra-hard red is a precision slot car component designed for competitive anglewinder builds. Its rigid construction ensures consistent pinion-to-crown mesh, reducing transmission play and delivering lap-after-lap reliability. Compatible with NSR anglewinder chassis, this mount is the go-to choice for club racers and advanced hobbyists looking to eliminate variability from their drivetrain setup.
