PRO R-II one-finger controller

The PRO R-II: the most refined evolution of the electronic controller for a finger from Sloting Plus

The PRO R-II (ref. SP130038) is the latest iteration of the renowned PRO family from Sloting Plus, 100% electronic controllers with banana plugs that have earned a fixed place in the hands of the most competitive drivers in clubs. This new version is not just a simple facelift: it incorporates a new microcontroller with greater capacity and speed, a renewed sensor, and rewritten software that significantly changes the on-track behaviour.

Key Features and Improvements

• New software and microcontroller: greater processing capacity translates into a more progressive and controlled response in medium and wide radius corners. The controller is no longer as "reactive" in these situations as it was in the previous version, making it easier for drivers of all levels to handle.
• Improved sensor: more accurate reading of the trigger travel, contributing to a more natural modulation of the power delivered to the track.
• Intact PRO "kick" feature: the energetic and instantaneous response when opening the throttle —a hallmark of all PRO controllers with banana plugs— is maintained for drivers who enjoy that tactile sensation on corner exits.
• Recalibrated traction control: it has been slightly softened to broaden the spectrum of drivers it adapts to, without losing effectiveness in demanding track conditions.
• New one-finger trigger design: shorter and with a slight curvature —in line with the LITE EVO model— that improves ergonomics and the driving feel during long sessions.
• Repositioned curve selector: now located at the front of the controller, better protected from accidental knocks and with a more comfortable reading for many users.
• Trigger adjustment retained: the adjustment options for travel and spring tension remain unchanged from previous versions.

On-Track Behaviour

The most noticeable change of the PRO R-II compared to its predecessor is in the management of medium and wide radius corners. The new software moderates the trigger response in these sections, which in practice means less chance of unintentional over-acceleration and more margin for fine-tuning the driving line. In tight corners and standing starts, the PRO "kick" remains present with all its force, maintaining the competitive advantage when immediate power is needed.

The recalibration of the traction control expands the range of use: both the driver seeking a more predictable and manageable controller and the one who already masters the PRO family will find in the R-II a better-calibrated balance point than in previous versions.

Design and Ergonomics

The one-finger trigger —shorter and slightly curved— reduces fatigue during prolonged driving sessions. The new curve selector, integrated at the front, is protected during races and allows for quick consultation of the active position without needing to change grip.

Ideal for…

• Club drivers looking for a competitive electronic controller with refined response and customizable adjustments.
• Enthusiasts coming from previous PRO versions who want to feel the evolution without giving up the characteristic "kick."
• Those who prefer a one-finger trigger and value ergonomics during long training sessions.
• Mid-high level drivers who desire greater control in fast corners without sacrificing performance in slow ones.

Frequently Asked Questions

How does the PRO R-II differ from the previous PRO model?

The main difference lies in the software and microcontroller: the R-II is less reactive in medium and wide radius corners, giving the driver more control margin. Additionally, the one-finger trigger has changed shape —shorter and curved— and the curve selector has been moved to the front.

Does it retain the characteristic "kick" of PRO controllers with banana plugs?

Yes. The energetic response when opening the throttle that defines PRO controllers remains intact in the R-II. What has changed is the progression in fast corners, not the sensation of immediate power.

Can the trigger travel and spring tension be adjusted?

Yes, the PRO R-II retains all the adjustment options for the trigger —travel and spring tension— present in previous versions.

What type of track or racing modality is it designed for?

The PRO R-II is aimed at use on track, both in club circuits and home setups. Its traction adjustment and new behaviour in corners make it versatile for different layouts and competition levels.

Is it compatible with any track setup?

As it is an electronic controller, its compatibility depends on the power system and the type of connector used in each setup. Check your circuit specifications before purchasing if you have doubts about the connection.

How does the trigger of the PRO R-II differ from that of the LITE EVO model?

The new one-finger trigger of the PRO R-II shares design philosophy with that of the LITE EVO —shorter and with a slight curvature— although they are controllers of different ranges and specifications. The PRO R-II maintains the banana plug architecture and the electronic set typical of the PRO family.

The Sloting Plus PRO R-II SP130038 is a fully electronic one-finger trigger slot car controller featuring an upgraded microcontroller, redesigned software for smoother mid- and high-radius corner control, and a revised trigger shape for improved ergonomics. It retains the signature PRO throttle punch and full trigger adjustment options, making it a top choice for club-level slot racing enthusiasts seeking precision and control.
