Built for high-speed off-road action, the UDI RC Mini Sierra 4x4 Short Course Truck brings aggressive stadium truck performance to a compact 1/12-scale platform. Constructed around a rugged chassis with new-formula nylon suspension arms and durable front and rear bumpers, this Ready-To-Run RC truck handles harsh landings and rough trail obstacles with ease. At its heart sits a high-revving 2845-3800 KV brushless motor paired with a 45 An electronic speed control that supports 2S to 3S LiPo battery power, delivering explosive acceleration and high top speeds across grass, gravel, and dirt tracks.

Navigating tight corners and high-speed jumps is smooth and precise thanks to a full-time 4WD shaft-driven drivetrain featuring all-metal gears, steel universal joint dogbones, and a central metal drive shaft. Adjustable aluminium hydraulic oil-filled shocks absorb heavy terrain impacts, while an adjustable metal steering linkage driven by a 17g metal-gear servo delivers crisp, responsive handling. Equipped with functional front LED headlights for low-light driving sessions, high-grip all-terrain tyres, and a 2.4 GHz UA42-E radio transmitter, this versatile short-course truck offers incredible fun straight out of the box. Just add your choice of 2S or 3S LiPo battery, charge up, and hit the track.
