2–3-inch micro FPV motor
T-Motor F15 1106
T-Motor's 1106 for 110 mm micro quads, in 6000KV for 2S–3S and 4500KV for 3S–4S; on T-Motor's 3S bench the 6000KV pulls 244 g at full throttle on a Gemfan 2540 tri-blade.
- 110 mm micro quads, per T-Motor
- 2S–3S (6000KV) or 3S–4S (4500KV)
- 2- to 3-inch props on screw-on hubs
The spin is an illustration: the model turns at 1/600 of the no-load speed, and it is a generic 1106 motor drawn from T-Motor’s published sizes, not its exact design. Thrust, current and power are T-Motor’s bench figures for the GF2540*3 prop at 12.03 V, read straight across between its throttle steps. Its data starts at 50% throttle.
- Max thrust
- 244 g

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 GF2540*3: 122 g of thrust, 4.7 A, 56 W, 2.18 g per watt.
On your quad
1.5 : 1
Thrust to weight at full throttle: four motors pull 976 g with the GF2540*3 at 12.03 V.
At 60% throttle they pull 489 g, 0.8 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
Small and light
T-Motor pitches the F15 as small in size and big in power for 110 mm quads; it weighs 7.9 g with leads (7.8 g for the 4500KV).
244 g on 3S
At full throttle at 11.9 V the 6000KV pulled 244 g at 12.2 A on a Gemfan 2540 tri-blade; on 2S it pulled 181 g on a Gemfan 3025.

Two KVs
6000KV for 2S–3S and 4500KV for 3S–4S; the 4500KV pulled 280 g on HQProp's 3-inch two-blade at 3S and 258 g on its 65 mm prop at 4S.

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. 14.4 mm across, black, with an orange-anodised five-spoke top whose cut edges show silver. (T-Motor drawing and specs, T-Motor product page)
- Shaft. 1.5 mm, standing 3 mm above the bell, with four M2 prop-screw holes on a 5 mm circle round it. (T-Motor drawing and specs)
- Magnets and bearings. N50H arc magnets; NMB 502ZZ bearings. (T-Motor product page)
- Base. Orange-anodised, with four M2 holes on a 9 mm circle; 24 AWG leads, 75 mm long. (T-Motor drawing and specs, T-Motor product page)
How fast it spins
KV is the motor’s no-load speed per volt. With nothing on the shaft, the 6000KV 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 | 88,800 | 8,880 Hz | 53,280 |
| 4S full | 16.8 | 100,800 | 10,080 Hz | 60,480 |
| 6S nominal | 22.2 | 133,200 | 13,320 Hz | 79,920 |
| 6S full | 25.2 | 151,200 | 15,120 Hz | 90,720 |
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 11 × 6 mm stator, 14.4 mm bell, 13.3 mm height, 1.5 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.
