RT4 AW Offset Motor Mount -1-0mm ball bearings

The Scaleauto RT4 AW mount: anglewinder precision for demanding GT and LMP setups

The SC-6529AHD is the HARD version of the Scaleauto RT4 AW motor mount, specifically designed for anglewinder setups with an offset of -1/0mm. Made from extremely rigid black injected plastic, this mount meets the needs of tuners seeking stability, repeatability, and fine adjustment of motor positioning in competition.

Main features

• Motor type: Anglewinder — the motor is positioned at an angle to the rear axle.
• Motor angle: 12°.
• Offset: -1/0mm, designed for precise adjustment of the pinion-crown gear ratio.
• Material: Black injected plastic, HARD version (maximum rigidity).
• Compatibility with bearings: Suitable for ball bearings ø4.75 × 2.38mm.
• Includes: Hardware, brass bushings ø4.75 × 2.38mm, and various chassis anchoring supports.

Compatibility

This mount is designed for GT and LMP type bodies. Regarding motors, it is compatible with all long-can motors and Slot.it Flat motors, significantly expanding its range of application and making it a very versatile reference on the workbench.

Assembly and preparation

The kit includes everything necessary for assembly: hardware and the brass bushings ø4.75 × 2.38mm that ensure a proper fit before installing the final ball bearings. The different anchoring supports allow it to be adapted to various chassis geometries, making the task easier for the tuner without the need for additional machining.

The HARD version of the RT4 minimizes unwanted flexing of the motor-mount assembly under load, resulting in a more direct transmission and more predictable handling in corners. For those working with Sport track (Scaleauto, Slot.it), this type of rigidity in the mount makes a real difference on the stopwatch.

Ideal for…

• GT and LMP car tuners in 1/32 scale seeking precision in motor positioning.
• Enthusiasts who assemble or modify chassis for club racing.
• Those using long-can motors or Slot.it Flat motors in anglewinder configuration.

Considerations

This mount is designed for ball bearings ø4.75 × 2.38mm, which must be purchased separately if not already available. The brass bushings included in the kit are for assembly and preliminary adjustment, but optimal performance is achieved with the installed ball bearings. Always check the alignment of the pinion with the crown gear before finalising the assembly.

Frequently asked questions

What is the difference between the HARD version and other versions of the RT4?

The HARD version uses a higher rigidity injected plastic, which reduces deformations of the mount under load and improves transmission consistency. It is the recommended option for competitive use or for fast tracks where rear-end precision is critical.

Are ball bearings included?

No. The kit includes brass bushings ø4.75 × 2.38mm for assembly, but the ball bearings must be purchased separately. The mount is compatible with ball bearings of that same size.

Which motors is this mount compatible with?

It is suitable for all long-can motors and Slot.it Flat motors in anglewinder configuration.

What type of track is this mount recommended for?

It is optimised for Sport track (Scaleauto, Slot.it), although its actual compatibility will depend on the chassis and body it is mounted on. Always check your chassis specifications before choosing the offset.

What does the -1/0mm offset mean?

The offset indicates the lateral displacement of the motor shaft relative to the rear axle of the car. An offset of -1/0mm allows for adjustment of the distance between the pinion and crown gear to achieve correct meshing according to the chosen transmission combination.

Does the mount include the chassis anchoring material?

Yes, the kit includes different chassis anchoring supports in addition to the hardware and brass bushings, so there is no need to purchase additional items for basic assembly.

The Scaleauto SC-6529AHD RT4 AW motor mount is a high-rigidity anglewinder pod with a 12° motor angle and -1/0mm offset, designed for GT and LMP slot car bodies in 1/32 scale. Compatible with long-can motors and Slot.it Flat motors, it fits ball bearings ø4.75×2.38mm and comes with brass bushings and hardware included. A reliable choice for club racing and slot car tuning on Sport track systems.
