Great Construction

The use of a heat-resistant magnet attached steel case and double insulated windings,
high precision bearings, and rotor with a strong structure guarantees outstanding
performance and super durability.

High Torque

The 4 pole design will guarantee the motor to produce very large amounts of torque, 
a much faster acceleration response and a very stable
output of power to the drivetrain.

High Efficiency

The output performance of this motor has an efficiency of up to 90%.
In the same load condition, XERUN 4274SD has the higher efficiency but lower 
temperature than other 4274 motors.

Efficient Cooling Design

The aluminum ribbed heatsink housing can effectively reduce the motor temperature.

Compatible with the XERUN XR8 ESC

When pairing the XERUN 4274SD motor with the Hobbwing XERUN XR8 ESC,
the excellent match between ESC and motor will give you large torque
plus a very smooth and linear power band. Also runs on the Xerun 150amp perfectly 

Features

4.1 Sensor motor has the best control feeling and best performance, excellent for 1/8 scale competition.  
4.2 4 poles rotor, high efficiency (>90%), the additional heat-sink is unnecessary in most applications.
4.3 New design with lighter weight but bigger torque.
4.4 Higher power, faster acceleration and higher top speed.
4.5 Top quality materials:
Aluminum shell (case)
High quality magnets         
Copper wires of high temperature endurance         
Good quality bearings
4.6 Anti-broken rotor with special workmanship.
