The Vector K4 is the ideal brushless motor for every R/C driver. Whether offroad or onroad - the K4 is suitable for nearly all applications. It is available in five different windings, from 6.5T to 17.5T, and is fully re-buildable. The K4 includes many features of the successful Vector X-12 Stock-Spec competition motor, including the sensor positioning, oversized ball bearings, and HDS technology. The rotor is equipped with a 5mm sized shaft, which makes the K4 motor extremely robust. For weight reduction, the front part of the two-piece housing is made of heat-dissipating metal in a gun-metal look; while the rear part consists of high-quality synthetic material. LRP's K4 brushless motors come with pre-soldered silicone flex wires with gold coated connectors.
