Overview

Taking over from the original LIMITLESS 1/7 scale All-Road Speed Bash Roller, this latest evolution has been designed to go faster than ever before. ARRMA engineers have refined the already proven LIMITLESS platform to accept larger motors and higher-capacity ESCs — simply add your choice of electronics to create an RC supercar. Sitting at the very top of the ARRMA Speed Bash range, the LIMITLESS 1/7 scale All-Road Speed Bash Roller is the new benchmark for extreme speed running.

In a head-to-head challenge against the championship-winning Red Bull Racing RB7 Formula One car, the LIMITLESS proved its credentials by coming out on top. Reaching speeds of up to approximately 240 km/h, it covered 402 metres in just 8.6 seconds.

Because the LIMITLESS 1/7 scale All-Road Speed Bash Roller allows you to choose your own electronics package, you can tailor the power system to suit your needs as your speed-running skills develop. ARRMA has optimised this rolling chassis with drivetrain and motor mount components specifically designed for extreme 8S high-speed performance.

Key upgrades include a 3 mm anodised aluminium chassis plate that repositions the motor mount to accept longer motors. The easy-access sliding motor mount can accommodate larger diameter motors with an optional motor mounting plate, while the electronics module accepts larger ESCs and includes a waterproof receiver box.

Further improvements enhance stability and control at very high speeds. A 39T Mod 1.0 spool with a long rear outdrive is paired with a shorter rear centre driveshaft to equalise driveshaft lengths and reduce drivetrain vibration. Lower-ratio GP5 gears further reduce centreline drivetrain speed and vibration. A wider rear track increases stability, while stiffer front springs and a sway bar improve high-speed handling.

Carried over from the original LIMITLESS design are big bore oil-filled shocks mounted on black anodised front and rear shock towers. These keep the dBoots Hoons all-road tyres firmly planted, delivering maximum traction on tarmac, light off-road surfaces, loose gravel, short grass, dirt, and oval tracks.

In addition to being the fastest ARRMA Speed Bash vehicle, the LIMITLESS is also the first ARRMA “Rattle Can Roller.” The low-drag body comes unpainted, ready for you to create your own custom finish. Window masks and decals are included, while trim lines on the front and rear wings make it easy to fine-tune downforce and drag.

The ultimate RC speed machine experience starts here. Install your preferred electronics, paint the body in your signature colours, and build your own high-speed RC supercar with the ARRMA LIMITLESS 1/7 scale All-Road Speed Bash Roller.
