Key Features
- Optimised for 8S LiPo Power — The entire chassis, transmission, and motor mount have been engineered specifically for high-voltage 8S operation, allowing you to safely run more powerful motor and ESC combinations whilst maintaining reliability and component longevity. This optimisation is crucial for achieving the consistent 110+ mph speeds this platform is capable of delivering.
- 3mm Aluminium 6061-T6 Chassis Plate with Repositioned Motor Mount — The upgraded chassis plate not only increases longitudinal stiffness for high-speed stability but also repositions the motor mount to accept longer motors, giving you vastly more electronics options when building your system. This flexibility means you're not locked into a single motor choice.
- Easy-Access Sliding Motor Mount — The innovative sliding design accepts larger diameter motors, and when combined with an optional motor mounting plate, expands your selection even further. This modularity is essential for a roller platform where you're selecting your own drivetrain components.
- 39T Mod 1.0 Spool with Long Rear Outdrive — This transmission innovation, paired with a shorter rear centre driveshaft, achieves equal-length centre driveshafts that dramatically reduce drivetrain vibration at high speeds. Less vibration means more precision handling and better power delivery to the wheels.
- GP5 Lower Ratio Gears — These gears reduce centreeline drivetrain speed and vibration further, complementing the spool and driveshaft improvements to create a drivetrain system optimised for smooth, vibration-free high-speed running.
- Wider Rear Track for Increased Stability — The extended rear track width improves lateral stability at extreme speeds, preventing twitchy steering inputs and giving you confidence to push the vehicle to its limits on straights and through fast corners.
- Stiffer Front Springs and Sway Bar — These suspension upgrades improve high-speed handling characteristics, reducing body roll and maintaining consistent aerodynamic trim as you reach maximum velocity. Better handling means better control when running at 110+ mph.
- Big Bore Oil-Filled Shocks — With front shocks measuring 77mm and rear shocks 87mm, these aluminium dampers feature oil-filled chambers that provide consistent damping across the extreme speed range this vehicle is designed for. The black-anodised shock towers add both durability and visual appeal.
- Safe-D Input Cups Front and Rear — These safety features on both gearboxes protect your drive shafts and differentials from damage during hard driving sessions, extending component lifespan and reducing maintenance requirements.
- Waterproof Receiver Box in Electronics Module — The easy-access electronics module doesn't just accept larger ESCs; it incorporates a dedicated waterproof receiver enclosure, protecting your radio receiver from moisture and debris during outdoor bashing sessions.
- Clear Low-Drag Body with Custom Paint Potential — As the first ARRMA "Rattle Can Roller," this vehicle ships with an unpainted clear body ready for your personal colour scheme. The aerodynamically optimised design reduces drag whilst the included window mask and decal sheet provide everything needed for professional-looking customisation.
- Tunable Aerodynamics — Trim lines on both front and rear wings allow you to adjust downforce and drag characteristics, giving you the ability to fine-tune the vehicle's balance between straight-line speed and cornering grip based on your local track conditions.
- Independent Double Wishbone Suspension Front and Rear — This professional-grade suspension geometry provides superior control geometry throughout the suspension travel, maintaining consistent handling characteristics even when the vehicle is pushed to its absolute limits on the track.
- dBoots® Hoons™ All-Road Tyres on Speed Dish Wheels — These premium all-road compound tyres mounted on specially designed speed dish wheels deliver excellent grip across multiple surfaces — on-road, light off-road, gravel, grass, dirt, and oval tracks — whilst the low-profile tread pattern minimises rolling resistance for maximum speed.
- Heavy-Duty Servo Saver — This component protects your steering servo from damage caused by sudden impacts or lock-to-lock steering inputs, extending servo lifespan and ensuring consistent steering response throughout your driving sessions.
- Steel Driveshafts — Constructed from durable steel rather than plastic or aluminium, these drive shafts withstand the extreme torque and shock loads generated by 8S power systems and high-speed running without bending or breaking.
- Two Large Battery Straps with Perpendicular Hook-and-Loop Retention — The dual-strap system with perpendicular hook-and-loop fasteners provides reliable battery retention during aggressive acceleration, braking, and cornering, preventing battery movement that could affect weight distribution and handling.
- Oil-Filled Metal Gear Differentials Front and Rear — These differential units feature metal gears and oil-filled chambers, providing exceptional durability and smooth power distribution whilst maintaining the precision necessary for high-speed stability.
- 4WD Drivetrain — All-wheel-drive power delivery provides superior traction and stability compared to 2WD alternatives, crucial for maintaining control when running at 110+ mph speeds and during aggressive acceleration from a standstill.
Technical Performance
The ARRMA 1/7 LIMITLESS V2 Speed Bash Roller represents the absolute pinnacle of engineering excellence in the 1/7 scale high-speed RC car category. Built upon a precision-engineered 3mm anodised aluminium chassis, every component on this vehicle has been selected and optimised for one purpose: enabling you to safely and reliably achieve extreme velocities with absolute control. The platform is engineered to accept 50-series motors with maximum dimensions of 4.33 inches in length and 1.97 inches in diameter, with a 25mm screw pitch, giving you flexibility across a wide range of premium brushless motor options from leading manufacturers. The vehicle measures 730mm in length, 312mm in width, and 165mm in height, positioning it as a large-scale precision platform rather than a toy or beginner vehicle.
The transmission has been completely re-engineered for 8S LiPo compatibility, with the new 39T Mod 1.0 spool working in concert with an optimised driveshaft arrangement to eliminate vibration that would otherwise compromise handling at extreme speeds. The gear pitch has been standardised at 1.0 MOD across the drivetrain, and the internal gear ratio of 2.8:1 has been selected to balance acceleration with top-end speed capability. The vehicle's 406mm wheelbase provides excellent stability whilst the 310mm front track and 312mm rear track (wider rear track) geometry creates a planted, stable platform even when cornering hard at maximum velocity.
Suspension geometry is where the LIMITLESS V2 truly excels — the independent double wishbone design front and rear means the suspension maintains consistent geometry through its entire range of motion, essential for predictable handling at speeds where aerodynamic forces begin to dominate the vehicle's behaviour. The 77mm front and 87mm rear oil-filled shocks with their black-anodised aluminium towers provide progressive damping without harshness, keeping the dBoots® Hoons™ all-road tyres planted on the ground across multiple surface types. Ground clearance sits at 15mm, sufficient for light off-road bashings without compromising the low-slung aerodynamics that help maintain stability at high speeds.
The vehicle ships as a roller, meaning you must supply your own electronic speed control, motor, receiver, transmitter, servo, and batteries. The platform is rated for 4S, 6S, or 8S LiPo battery configurations, though ARRMA specifically optimises this platform for 8S operation, where the refined transmission and motor mount truly shine. An 8S system will demand an appropriately rated ESC (typically 160A or higher) paired with a 1250KV or lower motor to avoid overspeeding the transmission. The vehicle's 8.6 lb (3.9 kg) dry weight is remarkably light for a 1/7 scale platform, contributing significantly to the acceleration and handling responsiveness you'll experience once you've added your chosen electronics package.

Frequently Asked Questions
- Is the ARRMA LIMITLESS V2 Speed Bash Roller suitable for beginners? — This is not a beginner vehicle. ARRMA specifically markets it as suitable for intermediate to advanced drivers who understand high-speed RC operation, component selection, and the safety considerations of running a vehicle capable of 110+ mph. However, if you're a competent driver upgrading from smaller or slower vehicles, and you're willing to learn about electronics compatibility and 8S LiPo safety protocols, you can absolutely grow into this platform. Start with 6S power until you're completely comfortable, then upgrade to 8S components.
- What speed can I expect from the LIMITLESS V2? — ARRMA rates this vehicle at 110+ mph in optimum conditions with recommended electronics. The actual speed depends entirely on your chosen motor and ESC combination — higher KV motors will spin faster but with less torque, whilst lower KV options provide more punch. ARRMA has confirmed that in testing conditions, this platform achieved 150 mph speeds, completing a quarter-mile run in just 8.6 seconds, but such performance requires premium electronics and ideal conditions. Conservative estimates for a fully built 8S system would put you at 120-140 mph on a smooth, straight stretch of tarmac.
- What battery does the LIMITLESS V2 require? — This is a roller platform, so you select your own batteries. ARRMA recommends 8S LiPo configuration (achieved by running two 4S batteries in series), though the platform is compatible with 4S and 6S as well. For 8S operation, look for high-discharge-rate batteries (100C or higher) from reputable manufacturers like Spektrum, to ensure you have adequate power delivery for the motor and ESC you've chosen. At 8S, total pack voltage will be 29.6V nominal.
- Is this a ready-to-run RC car or does it require assembly? — This is a roller, not a ready-to-run vehicle. The rolling chassis arrives fully assembled and ready to accept electronics, but you must source and install a transmitter/receiver, servo, ESC, motor, and batteries before you can operate it. Approximate assembly time for the complete electronics package is 1-3 hours depending on your experience level. However, the chassis itself requires no assembly.
- What makes this better than other 1/7 speed bash vehicles? — The LIMITLESS V2 combines several advantages: it was engineered specifically for 8S power (most competing vehicles are optimised for lower voltages), it features a completely clear body allowing unlimited customisation, it incorporates the new 39T spool and shorter driveshaft design that reduces vibration at extreme speeds, and it includes the widened rear track for improved stability. The waterproof receiver box and easy-access electronics module are also exclusive features that make electronics installation and maintenance simpler than competitors.
- Can I run this vehicle in the rain? — The receiver box features waterproof sealing, but ARRMA doesn't rate the entire vehicle as fully waterproof. The motor, ESC, and other electronics will be exposed unless sealed separately. For wet-weather running, you'd need to add individual waterproofing to your specific electronics package. Running lithium batteries in wet conditions also introduces safety risks, so we recommend reserving this vehicle for dry-track use.
- How do I customise the clear body? — The clear body ships untrimmed and unpainted, supplied with a window mask sheet and decal set. You should trim the body using the provided trim lines, then mask the windows using the included masking sheet. Apply your chosen paint colour(s) using spray cans or airbrush (hence the "Rattle Can Roller" name), allow it to fully cure, remove the mask, and apply decals as desired. Professional paint results require proper technique and dry conditions — allow 24 hours minimum drying time.
- What size motor does the LIMITLESS V2 accept? — The motor bay accepts 50-series motors with maximum dimensions of 4.33 inches (110mm) in length and 1.97 inches (50mm) in diameter, with 25mm screw pitch mounting. The repositioned motor mount on the new 3mm chassis plate also accepts longer motors compared to the original LIMITLESS, expanding your options considerably. You can fit larger diameter motors with an optional motor mounting plate, giving you tremendous flexibility in motor selection.
- What transmission and gear ratio does this vehicle use? — The LIMITLESS V2 features a sophisticated transmission with a 39T Mod 1.0 spool, lower-ratio GP5 gears, and an internal gear ratio of 2.8:1. This ratio is designed to balance acceleration with top-end speed, though you can fine-tune it by changing the pinion gear size to suit your power system and local conditions. A smaller pinion increases top speed but reduces acceleration, whilst a larger pinion does the opposite.
- Does this vehicle include batteries and a charger? — No, batteries and charger are sold separately. You must source two 4S LiPo batteries for 8S operation, plus a compatible LiPo charger. ARRMA's completion guides recommend specific products from brands like Spektrum that work excellently with this platform.
- What is the wheelbase and track width? — The LIMITLESS V2 has a 406mm wheelbase, 310mm front track, and 312mm rear track (wider rear for improved stability). These dimensions create a planted stance ideal for high-speed stability.
- Is this a 4WD vehicle? — Yes, the LIMITLESS V2 is a 4WD platform with two oil-filled metal gear differentials (front and rear), providing power to all four wheels and excellent traction across multiple surface types.
