NSR Ferrari Hypercar chassis Slotit Kevlar two-component cradle

The chassis that carries the DNA of the Ferrari 499P at 1/32 scale

Cumbre Racing Technologies has developed the CRT-029SK with a clear objective: to provide competitive slot drivers with a mechanical base that meets the demands of the most challenging body in the NSR catalogue. The bicomponent process with Kevlar is not an aesthetic choice; it is an engineering decision that changes the car's behaviour on the track.

Material and manufacturing process

The bicomponent with Kevlar combines two materials into a single 3D-printed piece. The result is a structure that integrates areas of high rigidity with areas of greater elasticity, depending on where each property is needed. Kevlar adds impact resistance and a "torsion memory" that allows the chassis to regain its geometry after impacts or intense vibrations, which is critical in long endurance races where the accumulation of micro-impacts ultimately degrades conventional chassis.

This technology, unique to the Bicomponent Kevlar Series from Cumbre Racing Technologies, clearly elevates the CRT-029SK above standard resin or PLA printed chassis.

Compatibility and configuration

• Compatible body: NSR Ferrari 499P Hypercar
• Cradle type: Designed for Slot.it pods (SICH compatibility)
• Front geometry: Adjustable front axle height to optimise guide support
• Material: Bicomponent structure reinforced with Kevlar
• Reference: CRT-029SK

The choice of the Slot.it cradle as the mounting reference is not accidental: it is the most widespread pod system in club and organised series slot racing, with a wide range of interchangeable motors, crown gears, and pinions. The CRT-029SK maximises that ecosystem.

Track behaviour

The design of the CRT-029SK has been optimised to minimise friction with the track and maintain constant traction in corners. The adjustable front axle allows for guide pressure adjustment according to the type of track and session conditions, resulting in fewer derailments in fast corners and greater stability during braking.

The vibration absorption provided by Kevlar favours continuous contact of the braids with the track, reducing micro-cuts in current that can make the difference between winning and retiring in long races.

Assembly and preparation

Upon receiving the CRT-029SK, it is advisable to check that the Slot.it pod fits correctly before mounting the NSR body. The adjustable front axle should be set with the complete car on the track, ensuring that the guide supports with the appropriate pressure without lifting the rear end. A fine adjustment at this point can mean several tenths of a second per lap on tracks with many slow corners.

Who is the CRT-029SK aimed at?

This chassis is aimed at drivers who are already familiar with the operation of a Slot.it pod and want to take their NSR Ferrari 499P to the next level of performance. It is also a very interesting option for enthusiasts looking for a reliable and durable mechanical base for long club races, where chassis durability matters as much as top speed.

Frequently asked questions

What real advantage does Kevlar provide over a standard resin chassis?

Kevlar adds impact resistance and structural elasticity. While a standard resin chassis may crack or permanently deform after a strong impact, the bicomponent with Kevlar tends to absorb that impact and regain its geometry, extending the chassis's lifespan under competitive conditions.

Is it compatible with all Slot.it pods or only specific models?

The CRT-029SK is designed for Slot.it pods with SICH compatibility, which is the most common standard in the Slot.it catalogue for side motors. Before mounting, check that your specific pod fits within the chassis housing dimensions.

Does it work on Scalextric tracks or only on Sport tracks?

The chassis itself is compatible with any type of track; the guide and braids are the elements that determine compatibility with the track system. Mount the appropriate guide for the track you will be using —universal track (Scalextric, Ninco) or Sport track (Scaleauto, Slot.it)— and the CRT-029SK will work without issue.

Does it come assembled with the Slot.it pod included?

No; the CRT-029SK is supplied as an independent chassis. The Slot.it cradle or pod must be purchased separately.

Is it necessary to sand or treat the chassis before mounting it?

The bicomponent printing from Cumbre Racing Technologies offers a ready-to-mount finish, but it is advisable to check the support surfaces of the pod and the front axle to ensure there are no burrs that could affect the fit. A light touch-up with fine-grit sandpaper is sufficient if necessary.

Can I use this chassis for long endurance races?

Yes, it is precisely the scenario for which it has been designed. The impact resistance of Kevlar and the traction stability it offers make it especially suitable for long sessions where mechanical reliability is as important as speed.

The CRT-029SK by Cumbre Racing Technologies is a 3D-printed bicomponent Kevlar chassis for the NSR Ferrari 499P Hypercar body in 1/32 scale slot car racing. Engineered for Slot.it motor pod (SICH compatible), it delivers superior impact resistance, structural elasticity and adjustable front axle geometry. Ideal for competitive club racing and endurance events, this advanced slot car chassis is a top-tier upgrade for NSR Ferrari 499P builds.
