AW RT3 Offset Motor Mount -1mm Extra-Hard

Fine-tune your anglewinder geometry with the Scaleauto RT3 Offset -1mm Extra-Hard motor mount

When competition heats up, every tenth of a millimetre counts. The Scaleauto SC-6528C motor mount is designed for those who work on the chassis with precision: a specific tuning part for the anglewinder (AW) configuration with RT3 motor, combining a -1 mm offset from the standard position and an Extra-Hard hardness to maximise the rigidity of the assembly.

Function and performance

The motor mount is the element that secures and positions the motor within the chassis, and any variation in its geometry has direct consequences on the car's behaviour on track. In an anglewinder configuration, the motor is positioned at an angle to the rear axle, allowing for efficient weight distribution and lowering the centre of gravity.

• Offset -1mm: slightly shifts the motor position relative to the axle, allowing for adjustment of the belt tension or transmission gearing and fine-tuning the dynamic response of the assembly.
• Extra-Hard hardness: the stiffest version in the range. Minimises deformation under load, ensuring that the geometry defined during assembly remains stable throughout the race.
• Compatible with RT3 motor: designed and validated to work with the Scaleauto RT3 motor, commonly used in competition setups and advanced club preparations.
• Red colour for quick identification on the workbench.

Compatibility and assembly

This mount is designed for anglewinder chassis that accommodate the Scaleauto RT3 motor. Before assembly, it is advisable to verify that the chosen offset (-1mm in this case) is suitable for the belt length or transmission ratio you are using. An incorrect offset can generate excessive tension or slack in the transmission, directly affecting performance and component wear.

The Extra-Hard hardness level is particularly recommended for high-power setups or on Sport track systems where accelerations and braking are more abrupt. In softer configurations or for recreational use, the lower hardness versions of the same family can offer a more progressive response.

Usage recommendations

• Always check the belt play after mounting the support: the -1mm offset may require fine adjustment relative to your usual setup.
• If using the RT3 in competition configuration, the Extra-Hard version helps maintain consistency from lap to lap.
• Combine with other spare parts from the Scaleauto range to ensure total compatibility between components.

Ideal for…

Tuners and club drivers working on anglewinder chassis with RT3 motor who seek to fine-tune the transmission geometry. Also for those already familiar with the Scaleauto range who want to try different offsets to find the optimal configuration on their usual track.

Frequently asked questions

What is the difference between the hardness versions of the motor mount?

Scaleauto offers different hardness levels for this type of mounts. The Extra-Hard version is the stiffest: it minimises deformation under load and is the preferred option in competition. Softer versions better absorb track irregularities but may compromise geometric precision in high-power setups.

Is the -1mm offset compatible with all anglewinder belts?

Not necessarily. The offset modifies the distance between the motor pinion and the crown gear, so it may be necessary to adjust the belt length. Check your chassis specifications and verify the belt tension after assembly.

Is this mount suitable for any RT3 motor or just for a specific version?

It is designed for the Scaleauto RT3 motor in anglewinder configuration. If you have doubts about compatibility with your specific motor or chassis version, consult Scaleauto's technical documentation or contact us.

Can I use this mount on a chassis that is not Scaleauto?

It is primarily designed for Scaleauto chassis, but some tuners adapt it to chassis from other brands as long as the motor housing dimensions are compatible. This is a modification that requires prior verification.

Does the red colour have any technical significance?

In the Scaleauto range, the colour is typically used to visually identify the hardness or offset of the component, facilitating material management on the workbench. It does not imply any performance difference regarding the colour itself.

The Scaleauto SC-6528C is a specific anglewinder motor mount for the RT3 motor, featuring a -1mm offset and Extra-Hard compound for maximum rigidity. Designed for slot car competition and advanced club racing setups, it ensures precise transmission geometry on Sport track systems. A key tuning part for serious slot car builders looking to fine-tune their anglewinder chassis configuration.
