Details

The XRotor M4006 industrial multirotor motor features a rugged black housing, braided leads, and 330KV/350KV variants for different prop and voltage setups.

The XRotor M4006 setup is recommended for around 1 kg thrust per motor on a quadrotor with about 4.0 kg takeoff weight.

The XRotor M4006 motor features a spring + screw interlocking structure on the shaft for a more secure assembly.

XRotor M-4006 recommended setups pair a 6S LiPo with MP16*5.4" or MP17*5.8" propellers and XRotor Pro-H40A-6S/H60A-6S ESCs for 0.6–1.0 kg thrust per rotor.

Hobbywing XRotor M4006 motor construction uses labeled high-quality bearings, a carbide main shaft, and a steel outer rotor casing.

The XRotor M4006 motor features an open-frame design with a knurled shaft for secure prop mounting.

The XRotor M4006 330KV motor features a top propeller mount and compact, enclosed housing for straightforward installation on industrial drones.
