3DP rally guide with screw. Stem 3.5mm and 7mm.

Precision and grip on track with the Scaleauto 3DP Rally guide

The Scaleauto SC-1655A is a guide manufactured using 3D printing, specifically designed for competition and recreational use on universal track systems like Ninco and Scalextric. With a stem of ø3.5 mm and a total length of 7 mm, this guide offers a geometry tailored for rally bodies, where the height of the stem and the depth of the piece directly influence cornering behaviour.

Main features

• Manufactured using 3D printing for precise and repeatable geometry.
• Dimensions: 21.1 × 7 mm depth.
• Stem of ø3.5 mm.
• Supplied with included screw.
• Compatible with universal track: Ninco and Scalextric.
• Pack of 2 units.

Function and performance

The guide is the component that keeps the car within the track and transmits current from the braids to the circuit. A guide with the correct dimensions for the body and track we use makes a real difference in the stability of the car, especially in fast corners or typical elevation changes found in rally circuits.

The specific design for rally of this guide takes into account the greater ground clearance common in these models, adapting the depth and stem so that the car maintains contact with the track without penalising the height of the body.

Compatibility

This guide is intended for universal track, meaning Ninco and Scalextric circuits. It is not designed for Sport track (Scaleauto, Slot.it). Before installing, check that the chassis housing accommodates a stem of ø3.5 mm and that the depth of 21.1 mm fits with your car's body.

Assembly and preparation

The included screw facilitates assembly and ensures a firm hold without the need for additional parts. We recommend checking the condition of the braids before installing the new guide: changing the guide while leaving worn braids limits the performance of the upgrade. With both parts in good condition, the current transfer is clean and the car's response is immediate.

Ideal for…

Enthusiasts competing in rally categories at clubs or preparing their cars to get the most out of Ninco or Scalextric tracks. It is also a practical option for those needing to replace the damaged guide of a high-body model without resorting to generic parts that do not fit properly.
