Raptor Motor

The Sideways Raptor Motor: 21,000 rpm at the service of your slot preparation

Sideways is a recognised brand in the slot world for the precision and rigor of its developments. The Raptor Motor (SWMRAP) is its proposal for those who want to extract the maximum performance from their setups, with specifications that speak for themselves: 21,000 rpm and a torque of 350 gr/cm.

Main features

• Nominal speed: 21,000 rpm
• Torque: 350 gr/cm
• Brand: Sideways
• Reference: SWMRAP

The figure of 350 gr/cm of torque is particularly relevant: a motor is not only measured by its revolutions but by its ability to transfer force to the axle and, consequently, to the wheels. A generous torque like this translates into more vigorous corner exits and greater traction in acceleration zones.

Recommended applications

The Raptor is aimed at setups where a balance between power and controllability is sought. Its 21,000 rpm places it in a versatile usage range: suitable for club tracks with technical demands as well as for recreational setups where a qualitative leap is desired compared to a standard motor.

When integrating it into a chassis, it is advisable to consider the chosen motor configuration:

• Sidewinder (motor parallel to the rear axle): a common configuration in many resin and plastic chassis, with good weight balance.
• Inline (motor in line with the rear axle): favours a lower centre of gravity and a more compact mass distribution.
• Anglewinder (motor angled relative to the rear axle): a widely used intermediate solution in competition chassis.

Each configuration will exploit the torque and rpm of the Raptor differently, so the choice will depend on the type of chassis and the regulations of the category in which you compete.

Behaviour and performance

With 21,000 rpm, the Raptor is not an extreme top-speed motor, but a unit designed to offer progressive response and available torque over a wide working range. This makes it particularly interesting on tracks with many curves, where exit acceleration makes a difference more than maximum speed on the straight.

The torque of 350 gr/cm allows working with different gear ratios without the motor suffering excessively, giving the preparer room to adjust the setup according to the layout.

Usage recommendations

• Always check the braid pressure before installing a new motor: poor contact can generate sparks and affect performance.
• Carefully adjust the clearance between pinion and crown gear; the torque of this motor can accelerate wear if the transmission is not well aligned.
• Perform a gentle break-in period during the first minutes of use to settle the brushes and optimise long-term performance.
• Regularly check the guide tension and the condition of the braids if used in intense competition sessions.

Frequently asked questions

What does the figure of 350 gr/cm mean in a slot motor?

It is the torque, that is, the turning force that the motor can exert on the axle. A higher torque translates into greater acceleration capacity, especially in corner exits. It should not be confused with rpm, which indicate the speed of rotation in free run.

Is the Raptor Motor compatible with any slot chassis?

Compatibility depends on the size and format of the motor, as well as the chassis mount. Check the physical specifications of the motor and those of your chassis before installation. If in doubt, contact our team.

What type of track or category is it designed for?

Its 21,000 rpm and 350 gr/cm make it suitable for club tracks with regulations allowing medium-high performance motors, as well as for demanding recreational use. It is not aimed at extreme top-speed categories where much higher rpm figures are sought.

Which motor configuration best utilises the Raptor?

It works in the three common configurations (sidewinder, inline, and anglewinder), but the final performance depends on the chassis, gear ratio, and type of track. The inline setup usually favours a lower centre of gravity, which can improve corner stability.

Does it require a break-in period?

Yes. Like any motor with brushes, a gentle break-in period is recommended to settle the internal components and achieve the best long-term performance and durability.

Can I use it in official competition?

It depends on the specific regulations of the championship or club in which you participate. Always check the current regulations before homologating any motor for competition.

The Sideways Raptor Motor (SWMRAP) delivers 21,000 rpm and 350 gr/cm of torque, making it a solid choice for slot car builders and racers seeking a reliable, responsive power unit. Compatible with sidewinder, inline and anglewinder configurations, it suits both club competition and high-performance recreational setups. A well-balanced slot motor from Sideways, ideal for custom chassis builds and track-day tuning.
