The Hobbywing EZRun 3665SD G3 Sensored Brushless Motor is designed for use with 1/10 short course trucks. Featuring a rugged, waterproof design and high quality precision components for improved power and efficiency. It also features a hall sensor for precise throttle control.


  • The EzRun 3665 SD G3 features an improved waterproof sensored cable interface and an upgraded sensored mode to achieve motor temperature protection and perfectly matches to the EzRun MAX10 G2 ESC.
  • The high-precision Hall sensor components ensures that the rotor position output is always accurate and consistent, achieving excellent linearity and great throttle control.
  • The EzRun 3665 G3 motor adopts a high-precision bearing that is waterproof in the front end of the motor. The rear end of the motor uses precision iron cover with a smaller structure to improve the capacity, and at the same time, provides a higher bearing speed while keeping resistance low. The operation is smoother and more reliable.
  • Compared to the G2 motor, the motor temperature is greatly reduced under the same load conditions. The overall efficiency is 3% more effective while the maximum output power has increased by 5%
  • All the materials used on the EZRUN 3665 G3 motor (Motor casing, bearings, ultra-thin silicon steel sheets, high temperature-resistance copper wire, explosion-proof rotor, high-tolerance alloy shaft) are carefully selected and approved by our in-house engineers. Hobbywing is serious in providing users with an extraordinary performance for a long period of time.
  • The motor uses a modular detachable structure design for easy disassembly and daily maintenance. This helps to prolong the lifespan of the motor and maintains the efficiency of the motor over time.
