Adjustable hard angle cradle

The AV20561 adjustable hard anglewinder cradle redefines the anglewinder installation in long-can motors, separating the motor block and rear axle to ensure the gear ratio is exactly what you need.

Main features

The design of this cradle is based on a very specific premise: to separate the motor support from the rear axle support. This has a direct and very practical consequence — you can adjust the relative position of both elements and achieve a precise mesh between practically any pinion and crown gear available on the market, without compromises.

• Motor and rear axle in separate pieces, allowing for free adjustment of the transmission distance.
• Material: hardened plastic with fiberglass, denser and less fragile than standard plastic, with better response to motor vibrations.
• Anglewinder orientation: the motor is positioned at an angle to the rear axle, combining compactness and efficiency in transmission.
• Compatible with long-can motors.

Function and performance

In an anglewinder installation, the geometry between pinion and crown gear is crucial for the transmission to operate without play or unnecessary friction. With single-piece cradles, the adjustment margin is limited, and one often has to settle for suboptimal pinion/crown combinations. This cradle solves that problem at its root: by separating the motor housing from the axle support, the builder can adjust the distance between both axes and find the perfect mesh point for each configuration.

The fiberglass-reinforced plastic provides structural rigidity without adding unnecessary weight and withstands the heat and vibration cycles generated by a continuously running motor better.

Assembly and preparation

As it is adjustable, it is advisable to set the motor position before permanently securing the anchor screws. A common trick is to check the backlash by manually turning the pinion: a smooth mesh should be felt, without excessive dead space or tightness. Once the optimal position is found, secure both pieces and check again before gluing or screwing to the chassis.

We recommend cleaning the contact surfaces between the cradle and the chassis to ensure a flat seat and avoid parasitic vibrations during the race.

Ideal for…

This cradle is designed for builders and enthusiasts working with long-can motors in anglewinder configuration who want total freedom in choosing the gear ratio. It is especially useful when working with combinations of pinions and crown gears from different brands, where the distance between centres may vary slightly.

Considerations

• Designed exclusively for long-can motors. Check your motor dimensions before installation.
• Adjusting the distance between pinion and crown gear requires some practice; do not rush when securing the pieces.
• The fiberglass-reinforced material is stiffer but also somewhat less flexible against strong impacts: keep this in mind if racing on tracks with tight chicanes.

Frequently asked questions

What is the difference between a single-piece cradle and this two-piece cradle?

In a single-piece cradle, the distance between the motor shaft and the rear axle is fixed, limiting the usable pinion and crown gear combinations. In this cradle, as the motor and rear axle are independent, you can adjust that distance and achieve a perfect mesh with a much wider range of pinions and crown gears.

What motors is it designed for?

It is specifically designed for long-can motors. If you are unsure whether your motor fits, compare the dimensions of the motor housing with those of the cradle before installation.

What advantage does fiberglass-reinforced plastic offer over conventional plastic?

The material is denser and structurally stiffer, which reduces the micro-vibrations transmitted to the chassis and extends the lifespan of the part. Additionally, it is less prone to deforming with the heat generated by the motor during long sessions.

Can I use this cradle with crown gears and pinions from different brands?

Yes, that is precisely one of its advantages: the adjustability allows it to adapt to the slight differences in module or centre distance that exist between different brands on the market.

Is it compatible with resin chassis or only with plastic chassis?

The available information does not specify the exact type of chassis with which it is supplied or recommended. Please consult us if you have a particular configuration to ensure compatibility.

The AV20561 adjustable hard anglewinder motor mount is designed for long-can motors in slot car applications. Its two-piece construction — separate motor housing and rear axle support — allows precise adjustment of the pinion-to-crown distance, ensuring a perfect mesh with a wide range of gears available on the market. Made from fiberglass-reinforced hardened plastic for improved rigidity and durability. Ideal for slot car builders and racers looking for maximum flexibility in their drivetrain setup.
