Brief Description and Key Advantages

The BrotherHobby Avenger 3120 is a high-performance brushless motor optimized for heavy platforms: aerial photography, cargo delivery, professional multi-rotors, and specialized racing builds. The well-engineered stator architecture and high-quality aluminum casing contribute to efficient heat dissipation, reduced vibrations, and a long service life even under intense loads.

Technical Specifications

• 1. Motor Type: BrotherHobby Avenger 3120 brushless motor, ensuring high efficiency and extended lifespan.
• 2. KV Rating: Two options available:
  • 500KV — very low KV for maximum thrust and stable lifting of heavy loads; an ideal choice for heavy aircraft and cargo missions.
  • 700KV — a balance between thrust and speed, providing enhanced dynamics and good platform control.
• 3. Stator Size: 31 mm stator diameter.
• 4. Weight: Approximately 135 grams.
• 5. Housing Material: High-quality aluminum for efficient heat dissipation and increased durability.
• 6. Number of Stator Poles: 12 poles for stable and precise rotation across various flight modes.
• 7. Operating Voltage: Recommended operation at 6S (22.2V) or 8S (29.6V) depending on the selected KV and platform configuration.
• 8. Mounting Thread: Standard M3 thread for propeller attachment.
• 9. Application: Suitable for large multi-rotor drones, aerial photography and videography, research aircraft, specialized racing setups, and cargo transport.

This motor offers an engineering solution for those seeking a combination of power, mass, and efficient heat dissipation. Thanks to its aluminum casing and a high number of poles, the Avenger 3120 ensures smooth operation, reduced parasitic vibrations, and stable performance under sustained load.

Integration Recommendations: When selecting propellers and ESCs, consider the chosen KV (500KV or 700KV) and recommended voltage (6S/8S) to achieve optimal performance and avoid overloading the power system. For heavy platforms, we recommend testing various propeller sizes and ESC settings to achieve the desired thrust and efficiency.

The BrotherHobby Avenger 3120 is a reliable choice for professionals and enthusiasts designing powerful multi-rotors with high demands for thrust and stability.
