Twelve volts. 1.15 kW. Nine teeth. Counter-clockwise, read at the pinion face. Shorter can than the 200cc motors on the same shelf, and the pinion sits closer to the flange.
The direction is the trap. A ten-tooth clockwise motor will bolt to the same holes and then spin the engine backwards. On a 160cc single that usually means a kickback and a chewed bendix, not a clean start.
Where it goes. Flange to the engine block. Two 8 mm bolts, one main stud, one trigger spade. Nothing mounts to the airframe. M300 RTK itself runs on TB60 packs and six rotors, so the frame has no flywheel to engage.
The engine module. Ground power units and hybrid builds carry a small gasoline single. That is what this motor turns. If your machine is pure electric there is no ring gear, and no amount of torque will help.
One number. 021000032, stamped on the label. I found no cross reference anywhere public. Not in a dealer catalogue, not in a cross-reference tool. Treat the label as the only authority and compare it with your old unit before money changes hands.
Measuring the old one. Nine teeth. Counter-clockwise. Nose diameter with a caliper. Bolt spacing centre to centre. Photograph all four. A motor that looks right and meshes wrong will destroy the ring gear in a few starts.
Install. Negative lead off. Trigger spade. Main stud. Flange bolts last, in two passes, evenly. Do not shim to close a gap. A shim changes mesh depth, and mesh depth is what eats teeth.
Diagnosis. Key on, one click, nothing turning. That is usually voltage, not the motor. Test under load. Then the relay. Then the ground strap. A whine with no rotation is the bendix. Grinding right after a fresh install is the nose sitting crooked.
In the box. One motor. Terminals capped. Six months against DOA and winding faults. Sample orders of one are fine, production runs start at twenty. Ten to fifteen days.
Still unsure. Send a photo of the old label and the ring gear. I would rather talk you out of a wrong order than ship one.
