Professional-Quality Adjustable Analog Control – Made in USA

TheProfessor Motor Scale Racer PROis a professional-quality transistor analog controller offeringadjustable sensitivity and brakingat a sensible mid-range price.

Made in the USA by Professor Motor, it's our recommended step up for racers who want substantially more control and adjustability than a conventional resistor controller without moving into the price range of high-end competition models.

Unlike a fixed-resistance controller, the Scale Racer PRO can be adjusted to suit different cars, motors, track conditions, and driving styles. SeparateSensitivityandBrakecontrols let you tune both throttle response and braking to the car you're driving.

Key Features

• Made in USA by Professor Motor
• Transistor-Based Platinum Series Circuitry– Smooth, precise electronic throttle control
• Adjustable Sensitivity / Minimum Speed– Tailor initial throttle response to the car and motor
• Adjustable 25-Ohm Brake Control– Tune braking response to the car, track, and driving style
• Internal Aluminum Heat Sink– Helps manage heat under load
• Heavy-Duty 13-Gauge Silicone Leads
• Positive-Polarity Design
• Professional-Quality Constructionfor home and club racing

Double Adjustable – Sensitivity + Brakes

The two adjustments address some of the most important differences you'll encounter when switching between slot cars.

Sensitivity:Adjusts the controller's initial throttle response. This allows you to soften the response of a more powerful car or increase responsiveness with a milder motor.

Brakes:The adjustable brake control lets you change braking strength to suit the car and track. A car that stops aggressively may benefit from less braking, while another may need stronger braking to attack corners effectively.

Together, these controls make one controller useful with a much broader range of cars than a conventional fixed-resistance controller.

Connector Sold Separately – Choose What You Need

This listing is for the controller itself and does not include a track connector.

Rather than creating separate controller variants, we offer connector installation as a separate service. If you'd like your controller ready to plug into your track when it arrives, simply add the appropriateConnector Installationitem to your order.

Available installation options include:

• OmniSlotBox Gold-Plated 3-Pin Male XLR
• 24K Gold-Plated Banana Plugs
• OmniSlotBox Copper Alligator Clips

For OmniSlotBox systems, we recommend XLR.It provides a fast, secure, foolproof connection and is the standard we use on our own analog racing installations.

If you're unsure which connector your track requires, contact us before ordering and we'll be happy to help.

Recommended Applications

• Operating Voltage:14–19 volts
• Polarity:Positive
• Excellent for1/32 scale analog racing
• Suitable for manyHO and moderate-power 1/24 applications
• Recommended for motors through approximately16D class
• Well suited tohome tracks and club racing

Why Choose an Adjustable Transistor Controller?

A conventional resistor controller has a fixed resistance range. A controller that works beautifully with one type of motor may feel too abrupt or too slow with another.

The Scale Racer PRO's electronic design and sensitivity adjustment provide considerably greater flexibility. Instead of changing controllers when you change cars, you can adjust the controller to better suit the car.

Add adjustable braking and you have control over both sides of the corner:how the power comes in and how the car slows down.

A Good Match for OmniSlotBox

We particularly recommend the Scale Racer PRO forOmniSlotBox true analog operation.

OmniSlotBox can open a Carrera track to a remarkably wide range of analog cars—from relatively mild home-racing cars to much quicker competition equipment. Having adjustable sensitivity and braking makes it much easier to adapt one controller to cars with very different characteristics.

Add ourXLR Connector Installationservice and we'll prepare the controller for an XLR-equipped OmniSlotBox installation before shipping.

Note:This is a conventional analog controller for true-analog systems such asOmniSlotBox Prime, XMR, and OmniSlotBox 4. It is not a Carrera Digital controller and is not the controller type used for Emulator analog operation.

Jim's Racer Perspective

I'm Jim Cunningham, founder ofOmniSlotBoxand host of theSlotCarClubhousein Sherwood, Arkansas. I've been racing, building, tuning, restoring, and collecting slot cars since the 1960s.

The Professor Motor Scale Racer PRO is one of my preferred recommendations for racers looking for a capable adjustable controller without spending considerably more for a high-end competition model.

It provides the controls that matter:smooth throttle response, adjustable sensitivity, and adjustable braking. For many home and club racers, that's a very useful sweet spot between a basic resistor controller and a much more expensive competition controller.

Handle Colors

Professor Motor offers these handle colors: Clear, Red, Blue, Yellow-Green Fluorescent, Amber, and Black.

Our stocking preference is clear, and unless a specific color is requested we may ship clear or another available Professor Motor handle color. If you want a specific color, message us before ordering. When requested, a specified handle color can be drop-shipped directly from Professor Motor to expedite delivery.

Handle color does not affect controller performance.
