One lift motor for the CW-25. 130 mm bell, 24 mm deep, 2100 W. It goes on the arm, under the vertical rotor. Bracket, propeller and screws are not in the box.
Four of these hold the aircraft up at takeoff and landing. In between, a petrol engine does the work and the lift rotors stop. That duty cycle is why the motor is 2100 W and not 5000 W.
The number. JOU-M13024 is ours. JOUAV ships whole aircraft and payloads, not motors, and publishes no part number for this one. We checked their site, four dealers and the resale market. Zero hits. One number on the page, and it is the one we control.
CW-25 on paper. 4.35 m wingspan, 2.08 m fuselage, 6 kg of payload, 360 minutes in the air, 82.8 km/h cruise, 6500 m ceiling. A hybrid, so the endurance number belongs to the engine, not to these motors.
What the motors actually do. Vertical takeoff, transition, vertical landing. Minutes, not hours. A lift motor that has run 2000 hours of fixed wing time may have run 40 hours of real work.
A quad has no spare. One motor quits and the aircraft rolls. There is no five rotor mode here, no parachute in the box, no second chance at 30 m. If one feels rough in the hand, it does not fly.
Fitting. Battery off, four screws, and they go into the arm. Start them by hand and take two passes. The magnets pull the bell down hard once the last screw is out, and fingers are what usually get caught.
Wet and dusty. This one works off strips and fields. Wipe the bell, blow out the vents, keep the plug dry. Water in the connector reads as a stutter at low throttle, and that is usually the plug, not the winding.
Diagnosis, in order. Hand spin: rough or clicking is a bearing. Nose: burnt varnish is a winding. Meter: unequal resistance across the three leads is a shorted turn. One can hot while three are cool is a motor pulling current it should not.
In the box, one motor. Six months against dead on arrival and winding faults. One piece ships, twenty starts a production run, fifteen to thirty days. Ask for the rotation if you are replacing a pair.
