Motor King 50000rpm EVO 365gr/cm 12V Long Box High Magnet

The NSR King 50000rpm EVO is the most radical long-can motor in the NSR catalogue for 1/32 slot racing competition.

With 50,000 rpm at 12V and a torque of 365 gr/cm, this unit belongs to the most demanding range of motors that NSR offers for the long-can replacement segment. The EVO architecture is not just a cosmetic revision: it involves optimised internal winding and assembly to achieve a constant power delivery without sharp peaks throughout the motor's lifespan.

Main features

• Rotation speed: 50,000 rpm at 12V
• Torque: 365 gr/cm
• Format: long-can
• Technology: High Magnet
• Nominal voltage: 12V
• Reference: NSR3030

High Magnet: invisible grip on the track

The feature that most distinguishes the King EVO within the NSR motor family is its High Magnet effect. The reinforced magnetic field acts as an additional load on the car's rear axle, improving corner traction and reducing the tendency to skid on exit. On tracks with large radius variations, this property makes a real difference compared to standard magnetic motors: the car stays glued to the track at points where others begin to float.

Behaviour and performance on track

The combination of high torque and high magnetism makes it an especially effective motor on mixed circuits, where there are long straights that demand top speed but also chicanes and tight corners that require stability. Thanks to the 365 gr/cm of torque, it is possible to work with long gear ratios (pinion-crown with higher development) without sacrificing acceleration on corner exit. This allows for very flexible transmission configuration tuning according to the layout.

The long-can format is the standard for pods designed for motors of this size, so its integration into compatible chassis is straightforward and hassle-free.

Recommended applications

The King 50000rpm EVO is designed for club and competition drivers looking to extract the maximum from their cars in categories with free motor configuration. Its ideal usage profile includes:

• Speed championships on plastic or wooden tracks with fluid layouts.
• Endurance tests where reliability and consistent power are priorities.
• Mounting in long-can pods in NSR cars or other brands compatible with this format.

Usage recommendations

As with any high-performance motor, it is advisable to respect a progressive break-in period before demanding maximum performance. A brief period at low voltage helps to settle the braids and stabilise the operation of the assembly. Checking the pod tightness and the alignment of the pinion with the crown before each extended session significantly extends the motor's lifespan and maintains performance at its optimal level.

Frequently asked questions

What is the difference between the King EVO and other NSR long-can motors?

The King EVO is distinguished by its high torque of 365 gr/cm and, above all, by the High Magnet technology, which adds an extra magnetic load on the rear axle. Other NSR long-can motors offer different combinations of rpm and torque, designed for different driver and circuit profiles.

Is it compatible with all long-can pod cars on the market?

In general, the long-can format is a widely adopted standard by the main manufacturers of chassis and bodies for 1/32. Nevertheless, we recommend always checking the specifications of your car's pod before installation, as some specific geometries may require adjustments.

Is the High Magnet effect allowed in all championships?

It depends on the regulations of each championship or club. Some championships have limitations on the allowed motor magnetism. Before using it in official competition, consult the specific regulations of your category.

What power supply voltage does this motor need?

The NSR King 50000rpm EVO is designed to operate at 12V, which is the standard voltage in most slot 1/32 track installations.

Does it require a special break-in before use?

Yes. It is recommended to run the motor for a few minutes at low voltage (around 6-8V) before taking it to full power. This helps to settle the braids and stabilise performance, extending the lifespan of the assembly.

Can I combine this motor with any long-can pinion and crown?

Yes, as long as the pinion module is compatible with the crown you use. NSR offers a wide range of pinions and crowns in different modules and developments, allowing you to adjust the transmission to the profile of each circuit.
