Technical Performance
The ARRMA KRATON 6S V6 delivers exceptional technical engineering across every system. Powered by the Spektrum Firma 4074 brushless motor rated at 2050Kv, paired with the Firma 150A Smart V2 ESC featuring updated B5.12 firmware, this ready-to-run RC monster truck achieves verified top speeds exceeding 65 mph when configured with a 6S LiPo battery. The brushless motor technology delivers superior efficiency, minimal maintenance requirements, and instant throttle response compared to older brushed alternatives. The 1/8 scale platform measures 596mm in length, 466mm in width, and 216mm in height, with a dry weight of 5.61kg, positioning it as a serious competitor in the high-performance monster truck category. The chassis utilises an independent suspension design with adjustable 16mm oil-filled shocks mounted on black-anodised aluminium towers, providing both vertical compliance and tuneable handling characteristics. The vehicle's 4X4 drivetrain with 29mm differentials ensures power reaches all four wheels with intelligent torque distribution, critical for maintaining traction during acceleration and cornering. Battery compatibility is extensive—the vehicle accepts 2S, 3S, 4S, or 6S LiPo packs with a minimum specification of 5000mAh capacity at 50C discharge rating. The 150A ESC provides sufficient headroom for extreme power delivery whilst remaining protected against thermal shutdown through the integrated B5.12 firmware management system. All critical electronics including the motor, ESC, and servo feature waterproof construction to protected standards, making the KRATON 6S suitable for UK wet-weather bashing without component anxiety. The transmission system utilises steel driveshafts throughout the drivetrain for durability under extreme loads, whilst the front bumper, skid plate, and wing mount have all been upgraded to EXB Extreme Bash specifications for uncompromising toughness. The iconic KRATON body arrives factory-painted and decalled in striking multi-colour finishes (this specific version in green and black), featuring the convenient clipless quick-release retention system that simplifies maintenance between running sessions.

Frequently Asked Questions
- What's the difference between 4S and 6S performance on the KRATON 6S? — The KRATON 6S is designed to accept both battery configurations. On 4S (14.8V), you'll achieve fun, manageable speeds around 45+ mph with excellent control—ideal for developing driving skills, learning jumps, and bashing in tight spaces. On 6S (22.2V), the truck unleashes 65+ mph speeds with jaw-dropping acceleration and jump height, but requires confident throttle control. The Spektrum SLT3 transmitter includes a throttle limiter feature (50% or 75% mode) that helps you safely progress from 4S to 6S power by electronically capping top speed until you're ready for full power delivery.
- Is the KRATON 6S suitable for beginners? — The KRATON 6S is rated for skill level 3 (intermediate to advanced), making it better suited to drivers with previous RC experience rather than absolute beginners. However, it's an excellent upgrade vehicle for someone transitioning from smaller 1/10 scale RTR trucks. Starting with 4S battery power provides manageable performance whilst you learn the vehicle's handling characteristics, and the throttle limiter on the Spektrum transmitter adds an extra safety layer. If you're brand new to RC hobbies, consider starting with a smaller or less powerful vehicle before stepping up to the KRATON 6S.
- What battery does the KRATON 6S need and what's the runtime? — The KRATON 6S accepts 2S, 3S, 4S, or 6S LiPo batteries. For 4S operation (recommended for intermediate drivers), a single 4S 5000mAh 50C battery is sufficient. For 6S maximum performance, use a single 6S 5000mAh 50C battery. For 2S or 3S configurations, you'll need to parallel two or more packs together. Typical runtime ranges from 10–15 minutes depending on driving style, battery capacity, and voltage configuration. More aggressive driving and higher voltage (6S) will reduce runtime, whilst smooth driving and lower voltage (4S) will extend it.
- Is this truck waterproof? — The KRATON 6S is water-resistant rather than fully waterproof. The motor, ESC, and servo all feature waterproof construction to protected standards, allowing safe operation in wet grass, mud, light rain, and snow. However, avoid submerging the vehicle in water or driving through deep water crossings, as the body and chassis are not sealed. Always allow adequate drying time after wet weather operation before storing or charging batteries.
- What makes the EXB (Extreme Bash) upgrades important? — EXB stands for Extreme Bash and refers to reinforced components engineered specifically for brutal high-speed and high-impact running. The aluminium chassis plate, differentials, front bumper, skid plate, and wing mount have all been upgraded with stronger materials and geometry to withstand big air jumps, hard landings, and aggressive bashing. These upgrades reduce breakage rates and extend the vehicle's operational lifespan, meaning fewer repairs and more running time.
- Can I use this for competitive racing? — Whilst the KRATON 6S is incredibly fast (65+ mph) and agile, it's classified as a speed monster truck rather than a competition racing vehicle. It excels at casual high-speed bashing, big jumps, and speed runs across open terrain. For organised competition racing, you may want to consider dedicated racing platforms, though the KRATON 6S will certainly hold its own in many informal competitive environments.
- How does the clipless body retention system work? — The KRATON features ARRMA's convenient clipless quick-release body retention system, meaning the body simply clips onto the frame without requiring tools or fasteners. To remove the body for maintenance or repairs, you simply unclip it—no tools necessary. This design significantly reduces maintenance time and also provides built-in protection against body punch-through during impacts.
- What's included in the electronics package? — The KRATON 6S comes pre-equipped with a complete factory-installed Spektrum electronics suite: Firma 150A Smart V2 ESC (with updated B5.12 firmware), Firma 4074 2050Kv brushless motor, SLT3 3-channel transmitter with throttle limiting, SR315 DSMR receiver, and S665 waterproof steering servo. Everything is bound and tested from the factory, and you receive four AA batteries for the transmitter, allowing you to begin operation immediately upon arrival.
- What's the warranty on the KRATON 6S? — ARRMA provides a 2-year limited warranty covering manufacturer defects. This comprehensive warranty reflects the confidence ARRMA has in their engineering and build quality. Consult the manufacturer's website for complete warranty terms and conditions.
- Where can I source replacement parts and upgrades for the KRATON 6S? — RC Model Shop stocks an extensive range of genuine ARRMA replacement parts and optional upgrade components. The vehicle's popularity within the UK RC hobby community means parts availability is excellent. Our team can help identify the correct components for your needs.
