ARRMA are proud to introduce the KRATON 8S BLX Speed Monster Truck. Colossal 1/5th Scale size. Staggering 8S brushless power. This ARRMA 1/5th scale truck is primed for off-road blasting action however hard the elements fight back.
Immense from whatever angle you look at it. The KRATON 8S BLX is an all-new model from ARRMA. Every component has been designed super-sized and ARRMA tough.
Designed FAST. At the heart of the KRATON 8S BLX is the Spektrum FIRMA SMART 8S brushless power system that provides brutal acceleration and breakneck top speed.
Even stood still the vast footprint, aggressive styling and monster sized components give the KRATON 8S BLX an intimidating presence.
Designed TOUGH. The KRATON 8S BLX has 'ARRMA tough' DNA engineered into every component. Strong aluminum, durable steel and tough composite materials are used throughout to create the ultimate 1/5th scale speed monster truck.
Dominating any surface is simple when you pilot the KRATON 8S BLX. Battle-hardened to withstand a diverse range of environments, this all-terrain beast will take your breath away time-after-time.
Don't just bash. BLAST. The endless power from the Spektrum 8S brushless power system coupled with huge bash-tuned four-wheel independent suspension will allow you to blast across any terrain with ease.
Designed BIG. The KRATON 8S BLX is the largest ARRMA vehicle to date. Here the KRATON 8S BLX is shown next to the KRATON 6S BLX 1/8th Scale Speed Monster Truck for a size comparison.
Beautifully detailed. The punchy color scheme is available with bright green or orange accent colors. The body print scheme reveals more and more detail the closer you look. Roof protection rails reduce wear on the roof of the body when things get upside-down.
The body retention system features body clip retainers that tether the body clip to the body. Also featured are molded composite platforms that sit between the body and body clip, spreading the load from the body clip to protect the body in this area. These molded composite platforms rise up and protect the body post from wear.
Ultra-detailed light, grille and window decals add to the authentic realism of the KRATON 8S BLX Speed Monster Truck.
The KRATON 8S BLX employs a triple center brace system for maximum chassis durability. There are red anodized aluminum front and rear chassis to tower braces and a full length red anodized aluminum tower to tower brace. ARRMA TOUGH.
The backbone of the KRATON 8S BLX model is constructed from a 4mm thick 6061 T6 aluminum chassis plate. This chassis plate is beautifully laser etched with ARRMA branding.
dBoots COPPERHEAD 2 SB tires give you the ground-ripping traction needed to transfer the huge torque of the 8S power system onto your chosen surface. The tires are attached to tough composite multi split-spoke wheels that have steel reinforced 24mm hex hubs for ultimate durability.
The KRATON 8S BLX has two extremely generous battery trays. These are adjustable in length and have two self-adjusting hook and loop straps to hold your batteries in tight. Each battery tray has the capacity to hold batteries up to 7.08x2.16x2.08 inches (180x55x53mm).
Wire guides are integrated into the battery strap buckles to hold battery wires away from rotating transmission parts.
Beefy independent suspension systems are utilized front and rear. Independent suspension offers the very best off-road handling characteristics. At the heart of the suspension are huge red anodized aluminum coil-over-oil shock absorbers that have 24mm diameter shock bodies.
For ease of maintenance the motor on the KRATON 8S BLX model can be removed with the removal of just three screws. The vehicle features a black anodized aluminum motor heatsink and massive 50mm motor cooling fan.
The ESC, receiver and servo are mounted together to form an electronics module. For fast and efficient servicing this module can be removed from the vehicle with the removal of just five screws.
Front and rear differentials can be quickly accessed for tuning and maintenance purposes.
The front suspension features 18mm pivot balls that provide silky-smooth suspension and steering articulation. The front hubs have molded-in steel reinforcement for ultimate durability.
The KRATON 8S BLX features strong steel adjustable turnbuckles and tough composite gearbox moldings at each end of the vehicle. Durable steel CVD drive shafts used throughout.
An ultra-durable molded composite body protection tower in the middle of the chassis locates with a frame that is mounted to the cab roof of the body.
The tough molded composite body support frame in the cab of the body bolts to the roof protection rails on the outside of the body.
For ultimate strength in key areas the front and rear gearboxes, steering knuckles and differential cases feature strong steel reinforcement inserts that are over-molded with a tough composite material.
The 'Safe-D5' pinions on the 8S BLX models features 'D' shaped hole. This 'D' shaped hole, combined with the pinion retaining E-Clip on the end of the motor shaft, ensures you do not loose forward drive or braking force should the pinion set screw back-out.
The sliding motor mount is secured by three screws. Two are accessed from above and one is accessed from below. The center gearbox features a full steel drivetrain for ultimate durability.
The oil-filled center differential assembly is constructed of tough steel and lightweight machined aluminum. A huge 53 tooth steel gear locates on to the red anodized aluminum diff case. Full steel differential internal gears and steel outdrives transmit the awesome 8S power to the front and rear gearboxes.
Oil-filled front and rear differentials have huge spiral-cut differential main gears to handle the massive power of the 8S brushless system. Full steel differential internals and steel outdrives are deployed for maximum durability.
The included Spektrum FIRMA SMART 160A waterproof ESC provides smooth power control and is 8S LiPo ready.
Fitted with reliable IC5 connectors, quality 10AWG wire and sporting a built-in cooling fan to reduce heat during intense bashing action, the Spektrum FIRMA SMART ESC has over-voltage protection and a two-stage LiPo cut off for added cell management.
Smart, all-in-one telemetry and a fast 32-bit processor combine with adjustable high-power BEC to provide the ultimate driving experience.
The Spektrum 4685 1250Kv brushless motor supplies huge speed and torque and is perfectly balanced for use with the Spektrum FIRMA SMART 160A ESC unit.
A beautifully etched black aluminum motor can provides a premium look, whilst a four-pole internal configuration keeps the power supply smooth and consistent.
Huge 6.5mm gold bullet connectors allow fast and easy wire removal when you need to clean your truck.
The aluminum motor can offers increased heat dissipation.
An E-Clip groove at the end of the 5mm motor shaft allows the installation of an E-Clip that will retain the pinion on the motor shaft should the set screw loosen.
The Spektrum S905 steering servo benefits from metal gears and is fully waterproof.
To provide fast and consistent steering response, the S905 servo has a huge 528oz-inch (38kg-cm) of torque at 6.0v with an operating speed of 0.20sec/60° at 6.0V.
At 2.36 x 1.14 x 2.17" (60 x 29 x 55mm) in size, this high-power steering servo is built tough for 1/5 scale vehicles.
Take control with the included Spektrum DX3 transmitter. This transmitter is built around frequency-agile, DSMR 2.4GHz technology.
Teamed with the SR6110AT receiver you get stability control of AVC™ (Active Vehicle Control) technology in your vehicle. AVC technology creates a more enjoyable driving experience by managing the vehicle's driving characteristics and attitude.
For more information on the features of the DX3 please see the Spektrum website:
