M-Hybrid GTP Watkins Glen 2023 No. 25 - Pro Anglewinder RT4

The hybrid prototype from Watkins Glen arrives on the track in its most technical version

Scaleauto materialises in 1/32 scale one of the most striking prototypes of the 2023 IMSA season: the BMW M-Hybrid GTP No.25 from the BMW M Team RLL that took the start in the 6 Hours of Watkins Glen. Within the category of Modern Le Mans Slot Cars, this model arrives in Scaleauto's Pro range, designed for those seeking real competitive performance without the need to prepare the car before running it.

Highlighted technical features

The reference SC-6384 incorporates a selection of high-level components that define Scaleauto's Pro philosophy:

• Pro In-Flex RT4 soft chassis (grey): designed to absorb track imperfections and maintain contact of all four tyres at all times, especially in fast corners and elevation changes.
• Anglewinder configuration: the motor is mounted at an angle to the rear axle, achieving a more balanced weight distribution and a smooth, progressive power delivery.
• SC-0029 motor at 22,500 rpm: mounted on an RT4 bracket with -1 mm offset to lower the centre of gravity and improve stability during braking and corner exit.
• Hardened steel axles of 2.38 mm: rigidity and geometric precision for a backlash-free transmission.
• Plastic wheels on the front axle and aluminium on the rear: a combination that reduces inertia in the front end and provides mechanical solidity where it is most needed, in traction.
• RT compound tyres: high-grip rubber, balanced between adhesion and durability for long competition sessions.
• Advanced SC-1608B front guide: front position that improves response in chicanes and facilitates precise guiding on Scaleauto's Sport tracks.

Scale and level of detail

In 1/32 scale, the body captures the aggressive aerodynamics and complex geometry of the real M-Hybrid GTP: the low-profile nose, large diffusers, and the official livery of the No.25 from the BMW M Team RLL as it raced at Watkins Glen in 2023. The paint and decals are factory applied with the finishing level that distinguishes Scaleauto's Pro models from the rest of the range.

Track behaviour

The combination of the soft In-Flex chassis with the Anglewinder configuration and RT tyres places this model at a level of balance that is hard to find in a production car. The chassis flexes slightly in response to track undulations rather than bouncing, resulting in a more consistent and predictable drive. The advanced SC-1608B guide reduces derailments in tight chicanes and allows for confident apex attacks. For competition on Sport track systems (Scaleauto, Slot.it), it is ready to run from the first moment; with minimal adjustments to braid pressure and guide height, its response can be further fine-tuned.

Ideal for…

• Club drivers competing in modern prototype or GTP categories who want a competitive car without hours of prior preparation.
• Collectors interested in the current IMSA era and the GTP category, with models representing real races and numbers.
• Fans of modern Le Mans slot racing looking to combine historical value and performance on the track.

Aspects to consider

• This model is configured for Sport track (Scaleauto, Slot.it). For other systems like Scalextric or Ninco, a guide change may be required.
• The soft In-Flex chassis is optimised for circuits with continuous surfaces. On tracks with pronounced joints, it may benefit from an adjustment of the braid pressure.
• The Pro range from Scaleauto does not require special break-in, although, as with any competition slot car, initial laps at a moderate pace help to settle the tyres and transmission.

Frequently asked questions

Is it compatible with Scalextric circuits?

The model comes equipped with the SC-1608B guide, designed for Sport track (Scaleauto, Slot.it). To use it on Scalextric or Ninco circuits (universal track), you will need to change the guide to one compatible with that system.

What is the difference between Scaleauto's Pro range and the standard models?

The Pro models come standard with the In-Flex RT4 chassis, higher performance motor, hardened steel axles, aluminium rear wheels, and RT tyres. They are designed for club competition or for the demanding enthusiast who wants results from the first moment, without additional preparation.

Is the soft (grey) chassis the most recommended for competition?

The soft version of the In-Flex RT4 chassis is the most versatile: it better absorbs track irregularities and keeps all four tyres in contact on almost any type of circuit. If you compete on a very smooth and fast track, a stiffer version may provide more precision; but for most club circuits, the grey version is the reference option.

What motor does it have and how many revolutions does it have?

It features the Scaleauto SC-0029 motor, with a nominal speed of 22,500 rpm. It is installed on an RT4 bracket with -1 mm offset, which lowers the centre of gravity and improves traction stability.

Does the car represent a real number and race?

Yes. The No.25 reproduces the official livery of the BMW M-Hybrid GTP from the BMW M Team RLL driven by Connor De Phillippi and Nick Yelloly in the 6 Hours of Watkins Glen of the 2023 IMSA championship.

Does it require special maintenance before running it?

No special preparation is required. It is advisable to check the braid tension and guide height before the first laps, and to perform a gentle initial break-in to settle the tyres and transmission. From there, it is ready to compete.
