Product Description
Take high-speed off-road bashing to extreme limits with the 1/10 scale ARRMA Kraton 4S V2 BLX Speed Monster Truck, finished in a striking factory green graphics package. Built on an extended composite tub chassis with wider track dimensions, it features an aluminum-cased center differential, EXB (EXtreme Bash) differential gears, and heavy-duty steel driveshafts designed to absorb high-impact jumps and harsh landings. Driven by a Spektrum Firma 4S Smart brushless power system (2400Kv motor and 120A V2 Smart ESC), the Kraton 4S V2 delivers blistering top speeds while offering progressive throttle control, making it a formidable choice for intermediate and experienced RC enthusiasts seeking uncompromising off-road strength.
ATModels Bench & Track Notes
- Center Differential Dynamics: The V2 updates solved the biggest weakness of the original 4S platform by replacing the slipper clutch with an aluminum center diff. It absorbs drivetrain shocks far better when landing on full power.
- Battery Recommendation: We recommend running a high-discharge 4S LiPo (50C+ rating) to unlock the full punch and 55+ MPH top speed this platform is capable of reaching.
- Stance & Handling: The extended track width and longer chassis give this V2 significantly better stability through fast off-road corners compared to the original V1 design.
