The first 4-pole motor with a built-in chip which helps ESC identify it's a HOBBYWING motor (only when pairing it with the XeRun XR8 series of ESCs) and the XR8 ESC create a power system which is able to work in the "sensored" mode (at all times) and provide users with the better performance and smoother control. Note: this motor is compatible with other ESCs but unable to work in the "sensored" mode at all times.

The Turbo Timing which is widely used (by 2-pole motors) in 1/10 scale on-road racing can be enabled to unleash the utmost power of the motor when pairing the XeRun 3652/3660 G2 with the XeRun XR8 series of ESCs.

The HOBBYWING-patented "error-free" Hall sensing system adopted by the motor guarantees users the steady operation in the “sensored” mode. A separate high-speed high precision encoder always outputs the clean signals (indicate the position of the rotor) and protects the Hall sensing system from other signal interference.

The HOBBYWING-patented 4-pole-8-magnet "staggered pole" rotor with the extremely low cogging effect and torque pulsation greatly improves the driving feel around corners.

The use of double insulated windings (200? R-leveled), Japanese NMB bearings, super thin silicon steel sheets and the high-intensity adhesive (300?) guarantees users the outstanding performance and great durability. (With the strength of the motor is guaranteed,) the wheel hub design adopted by front & rear end bells effectively reduces the motor weight.
