Experience a whole new rush that racers have never though of pushing the big scale truck to pure competition levels. The ST-1 PRO is built to be the fastest track tool and provides better handling than any other competition truggy available. Specification: Length: 592mm (Includes rear wing) Width: 415mm+/-5mm Height: 182mm Wheelbase: 359mm ~ 365mm FR/RR Track: 335mm ~ 345mm/340mm Weight: 3300g Ground Clearance: 48mm Gear Ratio: 16.54:1 Behind the trophy, this truck has been armed with some no-nonsense competition parts, such as ultra-long suspension arms, and race proven 7075-T6 aluminum chassis for excellent handling. The hardened lightweight suspension pivot ball is another secret formula for winning. An oversized 150cc fuel tank meets ROAR Truggy racing regulations and a large fuel splash guard prevents fueling mistakes to guarantee you victory at the track. Many features worthy of attention are included in this truck such that you don't need to purchase optional parts to bulletproof this truck. For instance many parts, which were previously made from stamped aluminum, are now made with extremely rigid routed carbon fiber - the shock towers (4mm), front bulkhead top plate (3mm), steering rack (3mm), center bulkhead top plate (3mm), and even the radio tray (2.5mm). To summarize in one word, the ST-1 is the new definition of PERFORMANCE.
