Innovative 4-pole-8-magnet "staggered pole" rotor (Hobbywing-patented) with low cogging effect and torque pulsation greatly improves control feel. A built-in chip makes the motor easily identified by HOBBYWING ESCs. When pairing it with an HW sensored ESC (i.e. XR8 SCT/Plus), the Turbo timing can be activated for higher output. A magnetic ring mounted on the rotor protects the motor from signal interference and guarantees super stability in the sensored mode. With the mechanical timing adjustable from 20 degrees to 40 degrees, users are able to select different power output. The turbine design of the rotor accelerates the internal air circulation and reduces heat. Rebuildable design (partially rebuild-able) and a screw-less motor case for easy routine maintenance effectively prolongs the motor life and raises the motor efficiency. CNC machined aluminum housing, high purity copper windings, advanced rotor structure, high-quality alloy steel output shaft, high-precision bearings all combine for high durability and smoothness. New-style U solder tabs for easy soldering and wiring.
