Product overview
The Flash Hobby A3115 is a brushless motor rated at 272W, with a 900KV option and custom KV alternatives. Its physical architecture combines a 12N14P configuration with a CNC-machined 6061-T6 aluminum bell and copper-wire winding described as resistant to high temperatures. The motor design emphasizes high torque, while its construction features include precision rotor balance testing and an imported high-RPM bearing measuring 5 × 11 × 5mm. These details define the motor’s mechanical construction and electrical configuration choices.
For installation planning, the motor measures 37.1mm in diameter by 32mm and has a 5.0mm shaft. Its mounting interface is 19 × 19mm with four M3 mounting positions, providing concrete dimensions for matching the motor to a mounting structure. The cable specification is 16 AWG with a 300mm length, which also informs cable routing space. Weight is 117g including the cables. The configuration choices comprise 900KV or custom KV, with a stated rated power of 272W.
