Boxer 2-20h motor open/closed box

Power and flexibility in a single motor: the Boxer 2-20h from Slot.it

The Boxer 2-20h Motor (reference SIMN08CH) is one of the most established offerings in the Slot.it catalogue for those seeking a balanced motor, with clear performance figures and a construction that allows for various pod configurations. The ability to mount it in both open and closed long cans provides an unusual versatility in this range, making it suitable for different types of chassis and tuning projects.

Main features

• No-load speed: 21,500 RPM at 12 V
• Torque: 330 g·cm at 12 V
• Pod configuration: long, open or closed depending on mounting needs
• Included wires for easy direct installation
• Reference: SIMN08CH
• Manufacturer: Slot.it

Behaviour and performance

With 21,500 RPM and 330 g·cm at 12 V, the Boxer 2-20h operates in a medium-high performance range that is particularly interesting for club competition builds or recreational setups that prioritise consistency over raw power. The torque is sufficient for good traction in corners and offers progressive acceleration, without the abrupt character of more extreme motors.

The long can favours a more balanced weight distribution within the chassis, something that experienced tuners particularly appreciate in cars where mass distribution makes the difference between a twitchy car and a planted one.

Recommended applications

This motor fits well in tuning projects on chassis compatible with Slot.it's long can range, both in sidewinder configuration (motor parallel to the rear axle) and in other arrangements depending on the chosen pod. The inclusion of standard wires simplifies the installation process and reduces preparation time before hitting the track.

It is a common choice in club categories with free motor regulations or with RPM limits in the 20,000-22,000 range, where the combination of speed and torque offers a real advantage over more polarised options.

Usage recommendations

Before installing the motor, it is advisable to check the condition of the pod and ensure that the fit between pinion and crown gear is correct to avoid premature wear. A gradual break-in at reduced voltages during the first few minutes will extend the motor's lifespan and properly seat the braids and collector. Slot.it typically recommends not exceeding the nominal voltage continuously during break-in phases.

Frequently asked questions

What is the difference between the open and closed can in this motor?

The open can allows for easier access to the interior of the motor for maintenance or inspection, while the closed can offers greater protection against dirt and track particles. The choice depends on the intended use and the tuner’s preferences.

Does the motor include a pinion or crown gear?

The motor is supplied with included wires, but it does not specify that it comes with a pinion or crown gear. These elements must be selected and purchased separately according to the desired gear ratio.

Is it suitable for club competition?

Its 21,500 RPM and 330 g·cm at 12 V place it in an appropriate range for many club categories. It is advisable to consult the specific regulations of your championship before homologating the motor.

Which chassis is it compatible with?

It is designed to be mounted on long can compatible pods within the Slot.it range. To confirm exact compatibility with your specific chassis, we recommend checking Slot.it's technical documentation or consulting with us.

Can I use this motor in an inline configuration?

The motor's configuration (sidewinder, inline or anglewinder) depends on the pod and chassis it is mounted on, not the motor itself. The Boxer 2-20h can be used in different configurations depending on the installation set chosen.

The Slot.it Boxer 2-20h motor (ref. SIMN08CH) delivers 21,500 RPM and 330 g·cm torque at 12 V, making it a reliable choice for slot car racing and club-level competition builds. Long-can configuration available in open or closed versions, with cables included for straightforward installation. Compatible with Slot.it long-can motor pods and suitable for sidewinder or inline setups depending on the chassis used.
