Product overview
The BrotherHobby Avenger 3120 is an Avenger Series motor for FPV drone propulsion, offered in 500KV and 700KV versions. Its physical construction combines an Al 7075 base casing and bell cap with a hollow titanium alloy shaft. Internally, the motor uses a 12N14P configuration, a stator made from 0.2mm Kawasaki silicon steel, and N52H arc rotor magnets. Japanese NMB bearings are specified at 11x5x5 mm, adding a dimensional reference for the bearing assembly.
Integration interfaces comprise an M5 propeller adapter shaft thread and an M3 mounting bolt pattern measuring 19X19mm. The electrical specifications list 8S/12S LiPo cell counts and 16AWG wires measuring 30cm long, without assigning a cell count to either KV version. The stated weight is 142.7 with 30cm SR wires. This is a propulsion component for integration into a drone; its specified configuration does not constitute a complete flight platform or an airframe kit.
