ST4 G3
1:8 Electric-powered Brushless 4WD Racing Truggy
Brushless Formula Off-road
Combining with part stadium truck style of newly designed metallic bodyshell and part 1/8 scale monster truck's tough drivertrain inheritance including precise milled hard coating aluminum chassis and extra strong suspension arms, the ST4 G3 1/8th brushless powered RTR truggy formally announces its most popular racing class around the world! Equipped with amazingly powerful IBL 40/74 2000 KV motor with 80A Brushless ESC as well as 8kg full metal steering servo, the extreme brushless horsepower with the proven durability not only has made ST4 G3 the excellent electric truggy racer, but work as an optimized package delivering the ultimate in efficiency, speed, and run time. Moreover, fully equipped CVDs and 3 metal differentials also make ST4 G3 to blow the doors off the competition with more power, smoother control, better grip, and performance that makes it one of the fastest Ready-To-Race electric truggy available. Now ST4 G3 has been proved to be a formula for off-road driving fun that nothing else can touch.

The ST4 G3 comes equipped with an ACE RC BLC-80C race spec ESC and super torque 2000KV motor combo, front and center CVD universals, all fluid filled differentials, 17mm wheel hubs to mach up its powerful output.

*Transmission- The front and rear transmission of ST4 G3 is the same as the nitro truggy ST1, which comes equipped with a hardened steel differential rings that makes stripping a gear a barely mission impossible. All the diffs contain a full set of steel diff gears and diff fluid inside in combination with full set of bearings throughout the drive train to ensure the most smooth power transmission.

*Suspension- The front and rear suspension uses the same race proven composite nylon suspension arms as the nitro ST4 S3. The shock bodies are made of anodized aluminum with quick adjustment clips for ease of changes. The shock towers are made from 4mm thick aluminum plate with multiple shock mounting positions and the whole chassis is strongly stiffened with a compact molded chassis brace and cover. You can also fine tune for the optimal camber and toe setting with adjustable turnbuckles and suspension blocks for your demanding cornering and overall handling.

*Brushless Power- The power system is equipped with a powerful 80A ESC and a 2000KV super brushless motor that will give ST4 G3 super fast speed and huge torque. But the most important thing is that the ACE RC brushless power system enables you a longer play time due to less friction in the brushless motor comparing to other RTRs. Other multiple protection features, like low voltage cut-off protection, over-heat protection, throttle signal loss protection, motor blocked protection and splash/dust proof cover are just making the ESC bullet-proof.
