Twelve volts. 1.1 kW. Nine teeth. Counter-clockwise, read at the pinion face. Short body, steel shell, alloy nose cap, solenoid sealed against the side.
The direction is the trap. A ten-tooth clockwise motor bolts to the same flange and pushes the engine the wrong way. On a 158cc single you hear it once, then the bendix is gone.
Where it fits. Flange to the engine block, one main stud, one trigger spade. Count the holes on your old unit before ordering. Two-bolt and three-bolt housings both exist at this size and the spacing is not the same.
The airframe side. Matrice 30T is the thermal member of the M30 line. 41 minutes of flight, IP55, minus 20 to 50 degrees, 23 m/s top speed, 7000 m ceiling, 15 km O3 Enterprise link.
Payload. 12 MP wide, 48 MP zoom, 1280 by 1024 thermal, laser rangefinder, all on one gimbal. Two TB30 packs, 3.77 kg all up. Electric throughout. No flywheel, no ring gear.
What it turns. A 158cc gasoline single, the kind used on ground power carts and hybrid test benches. That engine has a ring gear. This motor is the thing that spins it.
One number on the label. 021000028. Nothing public indexed it. No dealer list, no cross-reference hit, no auction listing. So the label is the only authority I can offer.
Check before ordering. Four photos of the old unit. Teeth counted by finger. Nose measured with a caliper. Bolt spacing centre to centre, plus the hole count on the flange.
Fitting order. Negative lead off. Trigger spade. Main stud. Flange bolts last, two passes, even torque. No shims to close a gap. Shim thickness changes mesh depth, and mesh depth is what eats teeth.
No crank. Key on, one click, nothing. Battery under load first, then relay, then ground strap. Whine without rotation is the bendix. Grinding straight after a fit is a nose that is not square. In the box: one motor, terminals capped. Six months against DOA and winding faults. One piece ships. Twenty starts a run. Fifteen to thirty days.
