Product overview
The FlashHobby MT4108 is a brushless DC motor with 380KV, 500KV and 620KV options, plus custom KV. The motor measures 47 x 25.8mm and weighs 112.0g including its cables. Its mechanical interfaces comprise a 4.0mm shaft and a 19*25mm(M3*4) motor mount. The motor cable is specified as 18#AWG with a length of 220mm. These dimensions describe the motor component, with the stated weight explicitly including the cables rather than the motor alone.
The MT4108 combines a CNC-machined 6061-T6 aluminum bell with 48SH-grade magnets and high-temperature-resistant copper wire winding. Its construction features include a precision-balanced rotor test and a high-RPM imported NSK/NMB bearing. The motor carries two conflicting architecture descriptions: a 24N22P configuration and a 12N14P high-torque motor design. That discrepancy leaves the motor's configuration ambiguous; both designations remain material to its specification, alongside the distinct shaft, mounting, cable and KV details.
