Measured and Progressive Performance: the SC-27 Sprinter 1 Jr from Scaleauto

Scaleauto has been a benchmark in the manufacture of slot motors for years, and the SC-27 Sprinter 1 Jr (reference SC-0027B) is a clear example of its philosophy: balanced performance, honest technical data, and components designed to last. With 18,000 rpm and a torque (MPM) of 14.5 g·cm, this motor sits in an accessible yet genuinely competitive performance range within the Junior categories.

Main Features

• Nominal Speed: 18,000 rpm
• Torque (MPM): 14.5 g·cm
• Reference: SC-0027B
• Brand: Scaleauto
• Series: Sprinter 1 Jr

Recommended Applications

The SC-27 is aimed at Junior categories, those classes that prioritise driver progression and equality of means over raw power. It is an ideal motor for both those starting in club competition and those looking for a regulated category where the difference is made by the driver, not the motor.

Its rpm range and torque also make it an interesting option for street setups or recreational use where an excessively twitchy motor is not desired, but enough push is needed to enjoy on track.

Behaviour and Performance

With 18,000 rpm, the SC-27 Sprinter 1 Jr is not a pure attack motor, but a driving motor: it responds well to throttle modulation, facilitates corner recovery, and reduces wear on tyres and braids during long sessions. The torque of 14.5 g·cm provides the necessary traction for controlled starts and accelerations without sacrificing drivability.

This type of balance between rpm and torque is precisely what Junior regulations seek: for the driver to learn to manage the car before moving on to more aggressive motors.

Usage Recommendations

• Always check the compatibility of dimensions with your chassis motor mount before installation.
• Adjust the gearing (pinion-crown ratio) according to the layout: technical circuits with many corners benefit from longer ratios that favour traction.
• Periodically check the condition of the braids and their contact with the collector to maintain motor performance over time.
• In regulated Junior categories, consult your club's regulations to confirm that the SC-0027B is homologated in your class.

Frequently Asked Questions

What does MPM 14.5 g·cm mean?

MPM is the maximum torque expressed in grams per centimetre. It indicates the turning force that the motor can exert on the axle. A value of 14.5 g·cm is suitable for Junior categories, providing sufficient traction without being excessively powerful.

What competition categories is the SC-27 Sprinter 1 Jr designed for?

It is specifically designed for Junior categories, where equality of performance among all participants is sought. It can also be used in street setups or in introductory club competition events.

Is it compatible with chassis from other brands?

Compatibility depends on the dimensions of the motor mount of each chassis. Scaleauto uses standard industry measurements, but it is always advisable to check the dimensions before installing the motor in a chassis from another brand.

What maintenance does this motor require?

Basic maintenance consists of checking the condition of the braids, cleaning the collector with a dry swab, and ensuring that the pinion is securely fixed and aligned with the crown. Avoid excess lubricant near the collector.
