Product overview
The FlashHobby 4112 Brushless DC Motor, designated MT4112, is a propulsion component for multirotor integration. Its physical envelope is 47 x 29.8mm, with a 4.0mm shaft and a 19*25mm mounting specification using M3*4 hardware notation. Weight is 151.0g including the cables, making that cable-inclusive figure relevant to installation mass. The motor cable specification is 18#AWG with a length of 220mm. Recommended propeller applications span 12–15 inches, providing a stated propeller-size range for integration planning.
The motor combines a CNC-machined 6061-T6 aluminum bell, 48SH magnets and high-temperature-resistant copper wire winding. Other stated features include a precision rotor balancing test and an imported NSK/NMB bearing described for high RPM. Configuration choices comprise 320KV, 400KV, 480KV or custom KV. A material ambiguity remains in the electromagnetic architecture: the configuration specification is 24N22P, while the design feature identifies 12N14P and describes it as high torque. These conflicting designations leave the exact configuration unresolved for procurement.
