Ready to seriously upgrade the speed and power of your 1/16 scale RC truck or buggy? This KingVal combo packs a serious punch. You get a 2445-sized sensorless brushless motor and a matching 35-amp electronic speed controller (ESC) all in one package. The motor has a KV rating of 3600, which is a great balance of torque and high RPMs for bashing and racing. It's built with quality features: a 4-pole, 12-slot design for smooth power, a CNC-machined aluminum heatsink can to keep things cool, high-purity copper windings for efficiency, and high-quality ABEC5 bearings. The shaft diameter is 2.3mm. The ESC can handle 2-3 cell LiPo batteries or 4-9 cell NiMH packs and has a 5V/2A BEC to power your receiver and servo. It's a universal fit for most 1/16th scale vehicles with a multi-mounting system for M2.5 screws. This is a major performance leap over stock brushed motors. Just make sure your drivetrain (gears, driveshafts) can handle the extra power! A fantastic, budget-friendly way to turn your small-scale RC into a little rocket.
