1S tiny whoop motor
T-Motor M0703
T-Motor's 0703 for 65 mm 1S tiny whoops: 1.7 g with leads and a plug-in JST connector; on 1S it pulls 23 g at full throttle on T-Motor's M12199 prop.

The spin is an illustration: the model turns at 1/600 of the no-load speed, and it is a generic 0703 motor drawn from T-Motor’s published sizes, not its exact design. Thrust, current and power are T-Motor’s bench figures for the M12199 prop at 3.7 V, read straight across between its throttle steps. Its data starts at 20% throttle.

What it pulls
T-Motor’s own bench test, one line per prop. Drag across the chart to move the throttle; the model above follows.
At 60% with the M12199: 16 g of thrust, 1.2 A, 5 W, 3.44 g per watt.
On your quad
0.1 : 1
Thrust to weight at full throttle: four motors pull 92 g with the M12199 at 3.7 V.
At 60% throttle they pull 62 g, 0.1 times the quad’s weight.
All-up weight is the quad ready to fly, with its battery and camera. The thrust is the maker’s static bench figure; in the air it is lower.
What you get for $11.90
1.7 g with leads
T-Motor says the low weight gives precise control and a fast response.

Plug-in leads
The leads end in a JST 1.25 plug for plug-in installation; T-Motor solders them to a PCB on the base so they don't break off.

One-piece bell
A Unibell in blue and silver, carrying on the M series design, which T-Motor says resists crashes better.

23 g on 1S
At full throttle on 3.7 V it pulled 23 g at 2 A on T-Motor's M12199 prop, at 44120 RPM.
What to pair it with

Bench data
Redrawn from T-Motor’s test reports. Thrust is static pull on a bench, more than you get in flight. Power is volts × amps; efficiency is thrust divided by power.

Inside the motor
A brushless outrunner: the coils stand still in the middle and the magnets spin around them. From the top down:
- Bell. One piece (Unibell), 9.6 mm across, anodised blue with silver machined edges on its six curved spokes. (T-Motor product page, T-Motor drawing, specs and test report)
- Shaft. 1 mm by the drawing, standing 5.1 mm above the bell. (T-Motor drawing, specs and test report)
- Base. A three-lobed blue base with three M1.4 holes on a 6.6 mm circle; the leads are soldered to a PCB on it and run 40 mm to a JST 1.25 plug. (T-Motor drawing, specs and test report, T-Motor product page)
How fast it spins
KV is the motor’s no-load speed per volt. With nothing on the shaft, the 19000KV version reaches about these speeds; a prop loads the motor and brings it down, typically to around 70–75% of these figures at full throttle.
| Battery | Volts | No-load rpm (KV × V) | Electrical frequency | ESC steps per second |
|---|---|---|---|---|
| 4S nominal | 14.8 | 281,200 | 28,120 Hz | 168,720 |
| 4S full | 16.8 | 319,200 | 31,920 Hz | 191,520 |
| 6S nominal | 22.2 | 421,800 | 42,180 Hz | 253,080 |
| 6S full | 25.2 | 478,800 | 47,880 Hz | 287,280 |
A 12-pole rotor has 6 pole pairs, so every turn of the shaft is 6 electrical cycles, and a six-step ESC switches the phases 36 times per turn.
About the 3D model
A generic outrunner drawn from T-Motor’s published sizes: the 7 × 3 mm stator, 9.6 mm bell, 1 mm shaft, 6.6 mm mounting circle and 9 teeth and 12 magnets. Anything T-Motor doesn’t publish is typical for a motor this size, and the bell’s spoked top, the base and the inside are a generic design, not this motor’s. The colours are read off the maker’s product photos. There are no logos or markings: it is our drawing, not the maker’s.
