NSR Anglewinder 32t Soft Crown for 3/32 Axle: Fine-Tuned Transmission for Competition

The NSR6632 crown is a 32-tooth gear specifically designed for anglewinder configurations, meaning those where the motor is mounted at an angle to the rear axle. Made from soft plastic, it provides smooth engagement with the pinion and better absorbs small transmission vibrations, resulting in quieter operation and reduced wear on the drivetrain.

The compatible axle diameter is 3/32, the most widely used standard in the NSR chassis and axle range.

Main Features

• Number of teeth: 32t
• Mounting type: Anglewinder
• Axle diameter: 3/32
• Material: Soft plastic
• Brand: NSR
• Reference: NSR6632

Anglewinder: What This Configuration Implies

In an anglewinder setup, the motor is positioned at an angle to the rear axle, allowing for a combination of advantages from both sidewinder and inline systems: a more centralised weight distribution and a relatively compact chassis profile. The anglewinder crown has a different attack angle compared to a standard sidewinder crown, making it essential to use the correct part for each configuration. Installing an incorrect type of crown would lead to poor engagement and accelerated wear.

Soft Plastic: Advantages in Transmission

NSR offers its crowns in various hardness levels. The soft version of this reference features greater flexibility in the tooth flanks, allowing it to absorb small misalignments between pinion and crown without straining the motor or generating excessive noise. It is the usual choice on wooden tracks with very smooth surfaces where smooth transmission is sought and minimal long-term wear is prioritised. On more demanding tracks or those with slight irregularities in the chassis, the soft version also acts as a natural damper for the drivetrain.

Gear Ratio and Tuning

With 32 teeth, this crown falls within the intermediate-high range of the NSR catalogue. The final gear ratio will depend on the pinion mounted on the motor: the fewer teeth the pinion has, the greater the multiplication and more acceleration available at the cost of some top speed. With 32 teeth on the crown, common club combinations range from 9 to 12 teeth pinions depending on the layout. On circuits with many slow corners, a crown with more teeth or a smaller pinion will favour corner exit; on fast layouts with long straights, adjustments in the opposite direction will be advisable.

Compatibility and Installation

This crown is compatible with NSR chassis that utilise anglewinder configuration and 3/32 axle. Before installing, check:

• That the chassis supports anglewinder mounting (refer to the corresponding NSR chassis documentation).
• That the motor pinion is compatible in module with NSR plastic crowns.
• The correct centring of the crown on the axle to avoid lateral rubbing with the chassis.
• The play between pinion and crown: there should be a small clearance allowing free rotation without rattling.

Common Mistakes

• Confusing the anglewinder crown with the sidewinder: although they may look similar visually, the gear geometry is different. Installing the wrong part will cause premature wear and power loss.
• Over-tightening the crown to the axle: excessive tightening can deform the soft plastic and cause eccentricity in rotation.
• Not checking the centring: an off-centre crown transmits vibrations to the chassis and makes the car unstable in corners.

Frequently Asked Questions

Is this crown suitable for a sidewinder setup?

No. The NSR6632 reference is specifically designed for anglewinder configurations. For sidewinder setups, you must use the crown corresponding to that type of transmission within the NSR catalogue.

What is the difference between the soft version and the standard version?

The soft version uses a more flexible plastic, which smooths the engagement with the pinion, reduces transmission noise, and better absorbs small alignment imperfections. The standard or hard version is stiffer and can provide a more direct transmission but is more sensitive to misalignments.

Which pinions is it compatible with?

You should pair it with NSR pinions of the same module designed for anglewinder transmissions. Consult the NSR catalogue or your chassis documentation to identify the appropriate pinion based on the motor you are using.

When should I change the crown?

When you notice visible wear on the tooth flanks, excessive play in the engagement, irregular noise in the transmission, or loss of acceleration without apparent cause in the motor. In club competition, periodic inspection of the drivetrain is part of regular maintenance.

Can I use this crown on any track?

The crown itself is independent of the track type. What varies according to the layout is the gear ratio that should be used, adjusting the crown-pinion combination. The soft version is particularly appreciated on wooden tracks for its smooth operation.
