3DP Chassis LMB SC-63 Hypercar Scaleauto for RT4 Motor Mount

3D SLS Polyamide Chassis for the Scaleauto Lamborghini SC-63 with RT4 Motor Mount

When aiming to maximise the performance of the Lamborghini SC-63 LMDh body, the factory chassis may fall short of the demands of club racing or fine-tuning sessions at home. This SC-9123B21 chassis from Scaleauto, manufactured using SLS laser sintering polyamide, meets that need exactly: a lightweight reference platform with controlled rigidity inherent to the material, designed for those who are already familiar with the RT4 motor mount and want to make the most of it.

Function and Performance

SLS polyamide is the material chosen by Scaleauto for its high-performance chassis because it combines low weight, some structural flexibility, and precise geometry that conventional injection moulding cannot always replicate. The result is a chassis that absorbs some of the track irregularities without losing alignment, which is especially valuable on circuits with tight profiles or pronounced joints.

The forward position of the guide redistributes the load on the front axle, improving response on corner entry and reducing the tendency to understeer that sometimes occurs in Hypercar configurations with long bodies and heavy rear ends.

Compatibility

• Body: Scaleauto Lamborghini SC-63 LMDh.
• Motor Mount: Scaleauto RT4.
• Scale: 1/32.
• Material: SLS Polyamide (3D printing by laser sintering).

Assembly and Preparation

The chassis is designed to accommodate the RT4 motor mount without additional modifications. The height adjustment of the front axle is done using M2 screws, allowing for precise and repeatable ride height adjustments between sessions. Before assembly, it is advisable to ensure that the RT4 motor mount is clean and well-aligned in its housing to guarantee correct transmission.

As it is an SLS printed component, the internal channels and housings come with a uniform finish; however, a light sanding of the contact areas between the chassis and body can refine the fit if any rubbing points are noticed.

Common Errors

The most common mistake when installing a 3DP chassis is over-tightening the motor mount fixing screws: polyamide tolerates static load well, but excessive tightening can create stresses that alter geometry. Manual tightening with a small amount of low-resistance thread locker is recommended. Another point to watch is the height of the guide: with the forward position, it is advisable to check that it does not rub against the track during elevation changes before the first running session.

Ideal for…

This chassis is designed for drivers who already use the Scaleauto RT4 motor mount and want an optimised base for the SC-63 body, whether in club racing, free practice format, or technical criterion collection builds. It is not an entry-level piece: it requires knowledge of the RT4 system and proficiency in assembling 1/32 slot car chassis.

Frequently Asked Questions

Is this chassis compatible with motor mounts other than the Scaleauto RT4?

No. The SC-9123B21 chassis is specifically designed for the Scaleauto RT4 motor mount. We do not guarantee compatibility with other mounts, as the geometry of the housings is unique to that system.

Does it work with Scaleauto SC-63 bodies of any decoration?

Yes, as long as it is the Scaleauto Lamborghini SC-63 LMDh body in 1/32 scale. The different decorations of the same mould are compatible.

Is SLS polyamide more fragile than conventional injection plastic?

Not necessarily. SLS polyamide has good impact resistance and controlled flexibility that often proves more beneficial on track than the rigidity of injection plastic. It is somewhat more porous on the surface, but this does not affect functional performance.

What screws do I need to adjust the height of the front axle?

The adjustment is made with M2 screws, standard in the 1/32 slot preparation universe. Ensure you have an Allen key or screwdriver of the appropriate size before starting assembly.

Can I use this chassis on Scalextric or Ninco track (universal track)?

The chassis itself is not tied to a specific type of track; compatibility depends on the guide you mount. Verify that the guide is suitable for the type of track on your circuit (universal or Sport) before running.

Does Scaleauto offer other 3DP chassis for different models?

Yes. Scaleauto has a line of 3D printed chassis for various models in its catalogue. Check the 3D Chassis, Fibre, Metal category in our store for available options.
