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).
Features:
- 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

All I can say is that at all box stock esc settings, on 6s its pretty much impossible to use anywhere close to 100% full throttle without flipping over or getting to a speed that is too high for a truggy and the wind and big tires cause it to catch flight or lose control, and I tried pinions from 15t to 22t, as i typically run 18t to 20t when Im just messing around away from the track. On 6s without dialing things back on the esc, this is a high speed crash waiting to happen haha. I would say that for 95% of people, 4s is where its at for truggies or buggies that arent set up for onroad/speed runs.
Anyway, I wouldnt hesitate to buy more of these motors for future builds and now after having over 20 packs through it, its still running 100% perfect.
Finally have plenty of power!
