Overview
The STX2® 2-channel radio that includes this new variation of the SENTON™ 4X4 3S BLX RTR offers a number of the very same functions discovered in high-end 2.4GHz radio systems —throttle and guiding reversing, throttle and guiding travel change, throttle limiting and more. The radio system likewise consists of an SRX200 2-channel water resistant receiver.
This sophisticated new RC system introduces you into terrain-commanding short course excitement, with tough parts, remarkable 3S BLX power, and top quality ARRMA® engineering letting you conquer anything that stands in your course. Accuracy aluminum, tough steel and composite products all combine to make the SENTON™ 4X4 3S BLX a short course car that's all set for hard-hitting action, right out of the box.
Ingeniously designed power, electronic devices, and differential modules are simple to gain access to and can be eliminated from the car quickly for upkeep. They make sure you spend more time bashing and as little as possible in the workshop. The main differential equipments have actually been super-sized with large pitch equipments to endure huge torque. The differential internals feature full-metal straight-cut equipments for similarly hassle-free operation.
Independent double wishbone suspension and coil-over oil shocks handle everything from quick speed runs to snow and mud chucking. No matter where you pick to slam, you'll stay stable and in control. The shocks are simple and easy to preserve, yet use all the efficiency needed for amazing all-terrain handling.
High-quality dBoots® FORTRESS SC tires on multi-spoke black chrome finish wheels provide the SENTON™ 4X4 3S BLX superb bite on a wide range of surface areas. You can take on any track with confidence. The aggressively styled short course truck body — offered in green or orange — looks terrific in action and even better up-close, where the attention to detail on the decal and body looks truly shines.
