The BrotherHobby Avenger 3120 700KV brushless motor is engineered for heavy-lift UAVs, long-range FPV drones, and professional multirotor platforms that demand exceptional torque, efficiency, and stability. Featuring a large 31×20 mm stator and a low 700KV rating, this motor is optimized for driving large propellers at low RPM, delivering powerful thrust with excellent efficiency.
Designed for 6S to 8S power systems, the Avenger 3120 performs best with 10–13 inch propellers, making it ideal for endurance flights, cinematic payloads, mapping, and industrial applications. Its smooth and linear throttle response ensures precise control and vibration-free operation, which is critical for high-quality aerial imaging and autonomous missions.
The motor bell is precision CNC-machined from high-strength aluminum alloy, providing outstanding structural durability and efficient heat dissipation during sustained high-load operation. Internally, premium stator materials and optimized windings minimize electrical losses, helping the motor run cooler and extend flight times.
A reinforced steel shaft combined with high-precision bearings ensures smooth rotation, low mechanical noise, and long service life even under continuous heavy loads. Each motor is factory-balanced to guarantee consistent performance and reliability straight out of the box.
