ROAR approved Innovative 4-pole-8-magnet "staggered pole" rotor (Hobbywing-patented) with low cogging effect and torque pulsation greatly improves control feel around corners.Built-in chip for making the motor easily identified by HOBBYWING ESCs. When pairing it with an HW sensored ESC (i.e. XR8 SCT/Plus), the motor can work in the sensored mode at all times with great output linearity. The Turbo timing is allowed to be activated for higher output.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 have different output power.Turbine design implemented by 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.CNC machined aluminum housing, high purity copper windings, advanced rotor structure, high-quality alloy steel output shaft, and high-precision bearings for high durability and smoothness.U solder tabs at the bottom of the motor for easy soldering and wiring.
