32-Tooth Angle Crown Gear for High-Performance Anglewinder Setups

The 32z Angle Crown (AV20658) from Avant Slot is a transmission component specifically designed for anglewinder configurations, where the motor is positioned at an angle to the rear axle. Its 32 teeth provide a gear ratio that balances torque and top speed, suitable for both club circuits and high-level tracks.

Technical Features

• Number of Teeth: 32z
• Diameter: 16 mm
• Compatible Axle: 2.38 mm
• Mounting System: M2 screw (included)
• Mounting Type: anglewinder

Function and Performance

In an anglewinder setup, the crown gear operates at an angle with the motor pinion, requiring very precise tooth geometry to ensure smooth and vibration-free engagement. This crown from Avant Slot is manufactured with the necessary tolerance to ensure fluid transmission from the first laps, reducing power loss and premature wear of the pinion and crown.

With 32 teeth and a diameter of 16 mm, it sits in a versatile range: it allows for competitive speeds without sacrificing acceleration torque, which is particularly valued on mixed layouts with slow corners and medium straights.

Compatibility and Mounting

The 2.38 mm axle is the standard used in competition slot cars from brands like Avant Slot. The anchoring with an M2 screw — which is included in the blister pack — ensures that the crown is fixed without play, avoiding one of the most common problems on track: crown slippage under load.

For optimal mounting, it is advisable to check that the axle is free of burrs and that the fixing screw tightens onto the flat area of the axle if present, or otherwise onto clean metal. A moderate tightening torque is sufficient; over-tightening may deform the crown hub.

Common Mistakes

• Mixing angle crowns with straight pinions: the tooth profile is different and the resulting engagement generates noise and accelerated wear.
• Not checking the tooth gap distance with the pinion before closing the chassis: too tight or too loose an adjustment directly affects transmission efficiency.
• Forgetting to include the M2 screw during assembly: without it, the crown may rotate freely on the axle under load.

Frequently Asked Questions

Is this crown suitable for a sidewinder or inline configuration?

No. This crown is specifically designed for anglewinder setups. In a sidewinder or inline configuration, straight crowns are used, with a different tooth profile. Using this crown in an incorrect setup would result in poor engagement and premature wear.

Is the M2 screw included or does it need to be purchased separately?

The M2 anchoring screw is included with the crown, as indicated in the product description.

What axle diameter is it compatible with?

This crown is designed for 2.38 mm axles, which is the standard size in most competition slot cars from Avant Slot.

What gear ratio do I get by combining this crown with a standard pinion?

The gear ratio depends on the number of teeth of the pinion it is combined with. Dividing 32 (crown teeth) by the number of teeth of the pinion gives you the ratio. A higher ratio provides more torque and lower top speed; a lower ratio provides higher top speed and less torque.

Can I use it on Scalextric or Ninco circuits?

The crown itself is an internal component of the car and does not depend on the track rail system. You can use this spare part in any slot car that has an anglewinder configuration with a 2.38 mm axle, regardless of the circuit it runs on.

The Avant Slot AV20658 is a 32-tooth anglewinder crown gear for 2.38 mm axles, 16 mm in diameter, secured with an included M2 screw. A precision slot car replacement part ideal for anglewinder setups, offering smooth power transmission and consistent performance on the track. Compatible with standard 2.38 mm axles used in competition slot cars.
