3-inch toothpick motor
T-Motor F1303
T-Motor's 1303 for 3-inch toothpicks and light 3-inch frames, 5000KV for 2S–3S, with a de-noising magnet for quieter flight; on T-Motor's 3S bench it pulls 177 g at full throttle on an HQ3018.

The spin is an illustration: the model turns at 1/600 of the no-load speed, and it is a generic 1303 motor drawn from T-Motor’s published sizes, not its exact design. Thrust, current and power are T-Motor’s bench figures for the HQ3018 prop at 11.94 V, read straight across between its throttle steps. Its data starts at 50% 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 HQ3018: 87 g of thrust, 2.7 A, 32 W, 2.75 g per watt.
On your quad
1.1 : 1
Thrust to weight at full throttle: four motors pull 709 g with the HQ3018 at 11.94 V.
At 60% throttle they pull 349 g, 0.5 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 $15.90
Quiet by design
T-Motor says a customised de-noising magnet makes it quieter, for smooth, soft flight and low noise indoors.

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. 16.5 mm across, black, with a gold-anodised band round the bell just below the top, and a three-spoke top. (T-Motor drawing and specs, T-Motor product page)
- Shaft. 2 mm, standing 4.5 mm above the bell, with four M2 holes on a 5 mm circle round it for screw-on props. (T-Motor drawing and specs)
- Magnets. Customised de-noising magnets, which T-Motor says make it smooth and soft. (T-Motor product page)
- Base. Black, with four M2 holes on a 9 mm circle; 24 AWG leads, 85 mm long. (T-Motor drawing and specs, T-Motor specs and test report)
How fast it spins
KV is the motor’s no-load speed per volt. With nothing on the shaft, the 5000KV 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 | 74,000 | 7,400 Hz | 44,400 |
| 4S full | 16.8 | 84,000 | 8,400 Hz | 50,400 |
| 6S nominal | 22.2 | 111,000 | 11,100 Hz | 66,600 |
| 6S full | 25.2 | 126,000 | 12,600 Hz | 75,600 |
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 13 × 3 mm stator, 16.5 mm bell, 10.05 mm height, 2 mm shaft, 9 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.
