Details

The Flashhobby 4108 brushless motor uses 48SH magnets, NMB/NSK bearings, and a screw-lock shaft for a solid, serviceable build.

The 4108 motor’s dimensioned layout helps confirm overall diameter, body length, and M3 mounting-hole spacing for a precise fit.

A standard brushless setup connects the ESC to the battery, receiver PWM signal lead, and the motor’s three phase wires (A/B/C).
