This is the Hobbywing 4274SD G2 Sensored Brushless Motor from Hobbywing, suited for us with most 1/8 Off-Road Buggy and Truggy options.

Full-Sensored Mode
The first motor (in the world) with a built-in chip which helps the ESC identify it's a Hobbywing motor (when pairing with XERUN XR8/XR8 Plus) and form a power system which can work in the "Full-Sensored" mode to provide users with improved performance and smoother control.

Note: this motor is also applicable to other ESCs, but it cannot work in the Sensored mode at all times.

Turbo Timing Technology
When pairing this motor with HW XERUN XR8 series of ESCs, the Turbo Timing, which is widely adopted in 1/10th scale on-road racing, can be enabled and unleash the utmost power of the motor.

Bi-Directional Adjustable Timing
The bi-directional adjustable mechanical timing, can meet the different power demands of various applications. Bi-Direction refers to CW and CCW operation of the motor.

Advanced Hall Sensing System
The first "error-free" Hall sensing system adopted by this motor guarantees users the steady operation in the "Full-Sensored" mode. A separate high-speed high precision encoder always output the clean signals (indicate the rotor) and not be affected by other signal interference.

Low Cogging Torque
The first motor adopted the innovative 4-pole 8-magnet "staggered pole" rotor has extremely low cogging effect and low torque pulsation (it's reduced by 85% when comparing with traditional 1/8th scale motors).


  • CNC-machined aluminum ribbed heatsink case with the sensor port covered by silicon O-ring seal guarantees users the effective heat dissipation and dust prevention
  • 4 M3 mounting holes and 2 M4 mounting holes on the front case are applicable to various motor mounts
  • New-style U gold-plated tabs with extremely-low internal resistance allows users to solder output wires easily and firmly on
  • The use of double insulated windings (240°C R-rated), NMB bearings from Japan, and the high-intensity adhesive (340°C) guarantees users the outstanding performance and super durability

Hobbywing Xerun 4274SD G2 Sensored Brushless Motor (2250kV)
This thing RIPS, SERIOUS power in combination with 4S and the Hobbywing 1/8 ESC, runs cool and smooth, perfect for a fun basher monster truck to a dedicated race buggy, this can do it. Fit and finish was beautiful, solder tabs are just right for 12 gauge wire, has both M3 and M4 tapped mount holes for hardware options to fit any 1/8 or large 1/10 vehicle. The low cog torque gives your car a very nice, controllable coast and when you need them the brakes are smooth and powerful.

First there is a typo on the motor size. It said 42x68 when it should be 42x74. Just got it today and I'll find out how well it handles next week.
