ARRMA KRATON 4S BLX V2 1/10 4WD RTR Brushless Speed Truck

The ARRMA KRATON 4S BLX V2 is a powerful 1/10 scale 4WD brushless speed monster truck designed for high-speed off-road driving, big jumps, wheelies and extreme RC bashing.

The ARA4408V2 combines ARRMA's proven KRATON platform with an updated Spektrum brushless power system, aluminium-cased centre differential, reinforced chassis and improved dirt protection.

Powered by a Spektrum FIRMA 3668 2400Kv brushless motor and Spektrum FIRMA 120A V2 Smart waterproof ESC, the KRATON 4S delivers impressive acceleration and can reach 55+ mph / 88+ km/h under suitable conditions.

Updated 4S Brushless Power

The KRATON 4S V2 is equipped with a Spektrum FIRMA 3668 2400Kv brushless motor and Spektrum FIRMA 120A V2 Smart waterproof ESC.

The system is designed for 3S and 4S LiPo batteries, giving drivers the option of strong 3S performance or the full power of 4S.

The Smart ESC provides telemetry compatibility with compatible Spektrum Smart equipment and offers programmable performance settings.

55+ MPH Performance

With a suitable 4S LiPo battery, the KRATON 4S V2 can achieve 55+ mph / 88+ km/h in optimum conditions.

The long-wheelbase chassis, 4WD drivetrain and large dBoots tyres provide excellent traction and stability for high-speed driving across dirt, grass, gravel and other suitable surfaces.

Aluminium-Cased Centre Differential

One of the major V2 improvements is the aluminium-cased centre differential.

The centre differential helps distribute power between the front and rear axles, improving traction and handling during hard acceleration.

This updated centre diff module is designed to provide smoother power delivery and improved grip compared with the earlier KRATON 4S configuration.

Reinforced Chassis

The V2 features an updated moulded composite chassis designed around the new centre differential module.

The chassis incorporates improved hinge-pin bracing, additional protection around the drivetrain and a redesigned dirt-drain system.

Updated side guards and dirt protection help prevent debris from entering the chassis during off-road driving.

Heavy-Duty 4WD Drivetrain

The KRATON uses a robust 4WD drivetrain designed to handle the torque generated by the 4S brushless system.

The vehicle features front and rear gear differentials along with the centre differential.

The drivetrain uses a 0.8 MOD gear pitch, providing a good balance of strength, efficiency and durability.

The final drive ratio is 12.48:1.

Independent Suspension

The KRATON 4S uses fully independent suspension with large oil-filled coil-over shocks.

The suspension provides the travel needed for rough terrain and big jumps while helping maintain traction during high-speed driving.

The aluminium shock bodies provide consistent damping and allow the suspension to be tuned for different surfaces and driving styles.

dBoots Off-Road Tyres

The KRATON 4S is equipped with dBoots multi-terrain tyres designed for aggressive off-road driving.

The tyres provide traction across dirt, grass, gravel and other suitable surfaces.

The wheels use durable 17 mm hexes for a secure connection to the drivetrain.

Spektrum SLT3 Radio System

The KRATON V2 includes a Spektrum SLT3 3-channel 2.4GHz transmitter and Spektrum SR315 dual-protocol receiver.

The SLT3 transmitter includes adjustable throttle limiting, allowing the driver to select 50%, 75% or 100% throttle.

This makes the KRATON suitable for drivers who want to gradually increase their driving speed and confidence.

The SR315 supports both SLT and DSMR protocols.

High-Torque Spektrum S662 Servo

The KRATON 4S V2 is equipped with a Spektrum S662 metal-geared waterproof digital steering servo.

The updated servo provides increased torque and durability for the large 1/10 scale truck.

Its aluminium centre case and metal gear train are designed to withstand the loads generated by high-speed off-road driving.
