PRO R-II controller for Two Fingers

The PRO R-II: the evolution of Sloting Plus's reference electronic controller

Sloting Plus has refined its PRO range with this second revision, the PRO R-II, maintaining everything that enthusiasts valued from previous versions and addressing the areas for improvement that track use had highlighted. The result is a 100% electronic controller designed for those seeking real finger response, not randomness.

Main features

• New microcontroller with greater capacity and speed, allowing for a more gradual and predictable response in medium and wide-radius corners, without sacrificing the characteristic "kick" of the PRO line.
• Redesigned two-finger trigger: improved ergonomics for greater comfort during long sessions. The support point has been lowered to accommodate those who apply more pressure on the trigger.
• New corner selector located at the front of the controller, better protected against accidental impacts and with more comfortable readability for most users.
• Adjusted traction control to cover a broader spectrum of driving styles and track configurations.
• Trigger regulation with travel and spring tension adjustment, just like in previous versions.

Track performance

The change in microcontroller is the core of this new version. The PRO R-II is less "reactive" in medium and long corners than its predecessor, resulting in greater confidence when accelerating before the tangent without the risk of launching the car. In tight corners and pit exits, the "kick" remains intact: the response is direct and immediate, a trait that has historically defined the PRO controllers with banana plugs from Sloting Plus.

The adjustment of the traction control is now more inclusive: whereas it was previously very tight for certain driver profiles, this version better balances the relationship between grip and driving freedom.

Ideal for

• Club competitors looking for an electronic controller with its own character and real adjustment margin.
• Enthusiasts who regularly drive with two fingers on the trigger and need sustained comfort.
• Drivers who want to explore mixed layouts —slow and fast corners— without changing controllers between sessions.

Considerations

Those coming from previous versions of the PRO line will notice the change in behaviour in open corners from the first minutes of running. The adaptation is quick, but it is advisable to dedicate a session to readjusting the usual braking points. New users of electronic controllers will find the PRO R-II a demanding yet highly educational entry point.

Frequently asked questions

How does the PRO R-II differ from the original PRO R?

The central difference lies in the microcontroller: the new one has greater capacity and processing speed, which smooths the response in medium and wide corners. Additionally, the trigger has been ergonomically redesigned and the corner selector has been moved to the front of the controller.

Can I adjust the travel and tension of the trigger?

Yes. The PRO R-II retains the travel and spring tension adjustment options that characterise the PRO line from Sloting Plus.

Is the controller suitable for club competition?

Absolutely. It is designed with that profile in mind: adjustable traction control, adjustable response, and the characteristic "kick" of PRO controllers, which many club drivers consider an advantage on technical layouts.

What type of track does it work best on?

The PRO R-II adapts well to mixed layouts. Its greatest virtue lies in medium and wide-radius corners, where the new version of the software offers a more progressive response. In tight corners, it maintains the lively response that has always characterised the PRO family.

Is the corner selector the same as in previous versions?

No. The selector is new and has changed position: it is now located at the front of the controller, better protected and, according to Sloting Plus, with improved readability for most enthusiasts.

Is it compatible with any track system?

Yes, being an electronic speed control controller by resistance/electronics, it is compatible with standard track systems —Scalextric, Ninco, Scaleauto, Carrera— as long as the connector is suitable for each driver's station.

The Sloting Plus PRO R-II two-finger trigger controller is a fully electronic slot car hand controller featuring an upgraded microcontroller for smoother throttle response in medium and wide-radius corners, a redesigned two-finger trigger for enhanced comfort, and a front-mounted corner selector for better protection and readability. Spring tension and trigger travel remain fully adjustable, keeping the characteristic "kick" response that PRO-series controllers are known for. An ideal choice for club-level slot car racing enthusiasts looking for precise, tuneable electronic control.
