One lift motor for the WingtraOne Gen II. 105 by 20 mm, 980 W. It bolts to the wing over the boom and turns a folding prop. Bracket and propeller are not in the box.
The airframe. 125 cm wingspan, 4.8 kg all up, 800 g of payload, 59 minutes of flight, 16 m/s cruise. Two motors hold it up for the vertical part, the wing does the rest.
The number. WIN-M10520 is ours. Wingtra sells a complete system and sends service through its own distributor network. No motor part number is published. We checked the site, three dealers and the resale market. Zero hits.
What that duty cycle means for a motor. Under a minute of hover at takeoff, another at landing, maybe two with a payload swap. The rest of the hour is fixed wing. A motor with 300 hours of airframe time has perhaps 10 hours of real load on it.
Two motors, one chance. There is no quad redundancy here. Lose one in hover and a 4.8 kg aircraft with a 61 MP camera on it rolls and falls. Nothing in the airframe recovers that.
Before every flight. Hand spin both. Rough or clicking is a bearing. A can that is still hot after landing while the other one is cool is pulling current it should not. Park it until you know why.
Fitting. The motor sits over the boom, four screws, and the prop folds back against the wing. Start the screws by hand. The magnets pull the bell down hard once it is close, and the windings are what gets nipped.
Weather. The airframe is IP54 and that rating covers the airframe, not the motor. No fog, no rain, no snow. Water in the connector shows up as a stutter at low throttle, and it 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 hot can against one cool can is a motor doing more than its share.
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. Tell us which side you are replacing.
