Black medium angle triangular motor mount

The support that keeps your anglewinder motor perfectly aligned

When we talk about fine-tuning in slot, the small details make the difference. The NSR1235 triangular motor mount is a preparation piece specifically designed for anglewinder configurations, where the motor is positioned at an angle relative to the rear axle. Its triangular geometry provides a rigid and stable anchoring point, eliminating vibrations and transmission losses that can ruin a fast lap.

The black finish is not just aesthetic: it is a treatment that protects the piece against wear and heat generated during competition.

Main features

• Anglewinder configuration: designed to position the motor at an angle relative to the rear axle, optimizing the mass distribution of the chassis.
• Triangular geometry: maximizes the structural rigidity of the anchoring with minimal material, helping to keep the weight low.
• Black finish: heat-resistant surface treatment for intensive use.
• Reference NSR1235: official NSR catalogue piece, with the guarantee of the brand's own tolerances.

Function and performance

The motor mount is one of the most critical components of any slot chassis. Its main function is to keep the motor perfectly aligned with the pinion and crown gear, ensuring that the transmission works without play or lateral tension. A poorly adjusted or worn mount directly translates into power loss, premature wear of pinions and crown gears, and even erratic behaviour in corners.

The medium angle variant allows for a balance between a compact drive shaft and a motor height that does not compromise the centre of gravity of the assembly, something especially valued in competition setups where every tenth of a second counts.

Assembly and preparation

The assembly of this mount follows NSR standards: precise fit, without play. Before permanently fixing the mount, it is advisable to check the alignment of the pinion with the crown gear using an alignment ruler or rolling paper to check the contact between teeth. Once correctly aligned, the locking must be firm to avoid any movement during the race.

We recommend periodically checking the condition of the mount, especially after intensive use sessions, to detect possible micro-cracks or deformations that may alter the alignment.

Compatibilities and applications

This mount is designed for NSR chassis in anglewinder configuration. To confirm the exact compatibility with your chassis and motor model, consult the official NSR catalogue or contact us: we help you choose the correct reference for your setup.

Frequently asked questions

What is the difference between a low, medium, and high angle mount?

The angle of the mount determines the inclination of the motor relative to the rear axle in an anglewinder configuration. A low angle places the motor closer to the ground, lowering the centre of gravity; a high angle raises it. The medium angle offers an intermediate point, balancing efficient transmission and mounting height, and is usually the most versatile option for mixed tracks.

Is it compatible with motors from other brands besides NSR?

The mount is designed following the standard dimensions of motors commonly used in competitive slot racing. However, exact compatibility depends on the motor format. Please consult us with your motor reference to confirm it before placing your order.

Can I use this mount on an inline or sidewinder chassis?

No. This mount is specifically designed for anglewinder configurations, where the motor is positioned at an angle relative to the rear axle. For inline (motor in line with the axle) or sidewinder (motor parallel to the axle) setups, there are specific mounts with different geometries.

How long does this type of piece last before needing replacement?

With normal use and periodic inspection, the lifespan is high. Mounts usually degrade mainly due to strong impacts in track accidents or excessive tightening during assembly. It is advisable to visually inspect it after each competition session.

Do I need special tools to mount it?

No special tools are required beyond the usual ones in slot preparation: precision screwdrivers and, to check alignment, a pinion-crown alignment ruler. A careful adjustment on the workbench is sufficient for a professional assembly.

The NSR1235 triangular motor mount in medium angle and black finish is a key component for anglewinder slot car builds. Designed for precise motor alignment, it ensures efficient power transmission and stable handling on the track. Compatible with NSR chassis in anglewinder configuration, this motor support is a must-have for serious slot car racers looking to fine-tune their setup. Ideal for 1:32 scale slot racing, club competition, and high-performance hobby builds.
