Product overview
The BrotherHobby R3.5 2205 Motor is a propulsion component for FPV drones, with a 2140KV specification and a 12N 14P motor configuration. Its physical construction combines a hollow titanium alloy shaft with N52H arc magnets and Japanese NSK bearings designated 8X3X4. The base casing and bell cap both carry the material designation AI 7075. These details describe an individual motor for integration into a drone propulsion system, rather than a complete flight platform or an airframe kit.
Mechanical integration is defined by an M2(12X12mm) bolt pattern, while the electrical wiring is specified as 20AWG. The configuration also identifies 16cm SR wires, although that detail appears under a weight entry and supplies no usable motor mass. The available integration details therefore cover the mounting pattern and wiring, without establishing a complete dimensional envelope or a matched propulsion configuration.
