Product overview
The GEPRC EM4218 350KV Motor is a propulsion component for 13–15 inch long-range FPV aircraft. Its construction combines a high-strength M6 steel shaft, N52H magnets, NMB bearings and many-strand copper winding in a 12N14P configuration. The magnetic circuit is designed for high torque. Electrical specifications comprise 350KV, 1800W maximum power, 60A peak current and 50mΩ interphase resistance, with a specified input of 33.6V using an 8S LiPo and a compatible ESC range of 60A–80A.
For mechanical integration, the motor measures φ49mm × 40.1mm, with a φ6mm shaft protruding 22.9mm and mounting holes spaced 30mm × 30mm. Its 800mm, 14AWG lead contributes to the stated 289g weight including wire. The supplied configuration is one motor with mounting hardware. Hardware descriptions differ: the screw specification identifies four M4*10 semi-spherical head screws and one M6 flange nut, while the package list identifies four M4*12 round head screws and one M6 anti-slip nut.
