The New King of Speed Bashers!
Taking over from the original LIMITLESS 1/7 Scale All-Road Speed Bash Roller, this new evolution of the LIMITLESS Speed Bash vehicle has been Designed FASTER so you can reach higher speeds than ever before! ARRMA engineers have improved the already proven LIMITLESS platform to accept bigger motors and larger ESCs just add your choice of electronics to create an RC super car. The LIMITLESS 1/7 Scale All-Road Speed Bash Roller sits at the very top of the ARRMA Speed Bash range. Its the new King of Speed Bashers!
In fact, in a head-to-head contest with the real championship-winning, Red Bull Racing RB7 Formula One car, the LIMITLESS 1/7 Scale All-Road Speed Bash Roller came out on top. Reaching speeds of up to 150 MPH, it ran a quarter mile in just 8.6 seconds!
Because the LIMITLESS 1/7 Scale All-Road Speed Bash Roller lets you pick and choose your own electronics package, you can adapt the power system to meet your needs as your speed run skills progress. ARRMA has refined this rolling chassis with transmission and motor mount parts that are optimized for 8S high-speed running.
New features to the LIMITLESS platform include a 3mm anodized aluminum chassis plate that repositions the motor mount to accept longer motors. Easy Access Sliding Motor Mount can fit larger diameter motors with optional motor mounting plate, while the electronics module accepts larger ESCs and incorporates a waterproof receiver box.
Additional changes have been made to increase stability for confident control at high speeds. The 39T Mod 1.0 spool with long rear outdrive combines with a shorter rear center driveshaft for equal length center driveshafts and less drivetrain vibration. Lower ratio GP5 gears reduce centerline drivetrain speed and vibration. Stiffer front springs and sway bar improve high-speed handling, and a wider rear track increases stability.
Carried over from the original LIMITLESS, big bore oil-filled shocks on black-anodized front and rear shock towers keep the dBoots Hoons all-road tires firmly planted for maximum traction over on-road, light off-road, loose gravel, short grass, dirt, and oval tracks.
Besides being the fastest ARRMA Speed Bash vehicle, the LIMITLESS 1/7 Scale All-Road Speed Bash Roller is also the first ARRMA Rattle Can Roller. The low-drag body comes unpainted, ready for you to personalize it with your own unique paint scheme. Window mask and decals are included. Trim lines on the front and rear wings make it easy to tune the downforce and drag.
The ultimate RC speed machine experience is here. Install your choice of electronics, paint the body in your signature colors, and create your own high-speed RC super car with the ARRMA LIMITLESS 1/7 Scale All-Road Speed Bash Roller!
