Our take on the ARRMA RC Truck KRATON 4X4 4S BLX 1/10TH 4 Wheel Drive SPEED MONSTER TRUCK RTR

The ARRMA Kraton 4X4 4S BLX is a 1/10-scale ready-to-run speed monster truck built for hard bashing. It runs a Spektrum Firma 3668 2400Kv brushless motor and 120A Smart ESC on 4S LiPo, with all-metal EXB gear diffs, a metal center differential and CVD driveshafts front and rear. A wide 17.72-inch track and long 21.54-inch chassis keep it planted at speed. It suits bashers who want a durable truck without building a kit, and it sits above 3S entry trucks in drivetrain strength while staying lighter and simpler than the 6S and 8S Kraton models.

About the ARRMA RC Truck KRATON 4X4 4S BLX 1/10TH 4 Wheel Drive SPEED MONSTER TRUCK RTR

The ARRMA Kraton 4X4 4S BLX is a 1/10 scale, four-wheel-drive speed monster truck. It comes fully assembled and finished, ready to run.

This version has a metal center differential for more traction. The updated chassis has a center diff module, hinge pin bracing and a dirt drain. The battery is held in place by an improved retention system with wire clips.

Power comes from a Spektrum Firma 3668 2400Kv brushless motor with an ARRMA heatsink and cooling fan. A Spektrum Firma 120A V2 Smart ESC runs cooler than before. The track is wide at both ends for aggressive bashing.

Questions and answers

What battery does the Kraton 4X4 4S BLX need?
It is designed for 4S LiPo packs and uses an IC5-compatible Spektrum Firma 120A Smart ESC. A battery and charger are not included, so budget for both.
Is it better than the 3S Kraton?
Yes for durability and power. The 4S truck adds a metal center diff, EXB all-metal gear diffs and EXB CVD driveshafts, which the 3S line does not have.
How does it compare with the 6S Kraton?
The 6S is larger, heavier and faster on 6S power. The 4S is lighter, simpler and cheaper to run, and still handles big jumps well.
Is it ready to run out of the box?
It comes fully assembled with the SLT3 transmitter and SR315 receiver installed. You add a 4S LiPo battery and a charger.
What is in the box?
The assembled truck, Spektrum SLT3 2.4GHz transmitter, SR315 receiver, and the manual. Battery and charger are sold separately.
Can it handle wet grass and mud?
