8–10-inch cinematic FPV motor
T-Motor Velox V3120
A 3120 for 8–11-inch X4 and X8 cinematic drones carrying heavy cameras, in 500KV for 6–12S and 700KV for 4–8S; the 700KV pulls 6028 g on a T-Motor 10.5-inch prop at full throttle on T-Motor's 32 V bench.
- 8–11-inch X4 and X8 cinematic drones
- heavy camera payloads
- 4S–12S, by KV
The spin is an illustration: the model turns at 1/600 of the no-load speed, and it is a generic 3120 motor drawn from T-Motor’s published sizes, not its exact design. Thrust, current and power are T-Motor’s bench figures for the HQ1145-3 prop at 32 V, read straight across between its throttle steps. Its data starts at 10% 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 HQ1145-3: 2,758 g of thrust, 21.4 A, 681 W, 4.10 g per watt.
On your quad
38.4 : 1
Thrust to weight at full throttle: four motors pull 24,944 g with the HQ1145-3 at 32 V.
At 60% throttle they pull 11,032 g, 17.0 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 $49.90
Built to run cool
T-Motor says its heat-dissipation design, a top with staggered ribs, keeps the motor cooler in flight.

Coated stator core
T-Motor calls it its first stator core finished by electrophoresis, for corrosion resistance and stability.

Two windings
500KV for 6–12S and 700KV for 4–8S, both for 9–11-inch cinematic drones, per T-Hobby.

Bench data for both KVs
Thrust, current, power, RPM and torque in 10% steps on 10- to 11-inch props at 24–48 V; at full throttle the 500KV pulled 7142 g on an HQProp 1145 at 48 V.
What to pair it with
Our reading of T-Motor’s numbers, so your build matches what the motor was tested with.
- ESC
- Peak current over 10 s is 79.4 A for the 700KV and 68.9 A for the 500KV. T-Hobby suggests T-Motor's V70A SE 4-in-1 stack. (T-Motor drawing, specs and test report, T-Hobby product page)
- Props
- T-Hobby recommends T-Motor's Cine 10.5 × 5. On it at full throttle the 700KV pulled 6028 g at 32 V and 3936 g at 24 V, and the 500KV 6837 g at 48 V. (T-Hobby product page, T-Motor drawing, specs and test report)
- Battery
- 6–12S for the 500KV, 4–8S for the 700KV. (T-Hobby product page)
- Frame
- 8–11-inch X4 and X8 cinematic and heavy-lift platforms, per T-Motor. Four M3 holes on a 19 mm circle. (T-Motor product page, T-Hobby product page, T-Motor drawing, specs and test report)

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. 37.2 mm across, dark grey, with a red top of radial fins round a knurled centre. (T-Motor drawing, specs and test report, T-Motor product page)
- Shaft. 5 mm inside and outside by T-Motor's table, with 8 mm of M5 thread; it stands 17.5 mm above the bell. (T-Motor drawing, specs and test report)
- Stator. 31 mm across and 20 mm tall, 12 slots under 14 magnet poles, with a core coated by electrophoresis. (T-Motor product page, T-Motor drawing, specs and test report)
- Base. Black, with four M3 holes on a 19 mm circle; 16 AWG leads, 250 mm long. (T-Motor product page, T-Motor drawing, specs and test report)
How fast it spins
KV is the motor’s no-load speed per volt. With nothing on the shaft, the 700KV 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 | 10,360 | 1,209 Hz | 7,252 |
| 4S full | 16.8 | 11,760 | 1,372 Hz | 8,232 |
| 6S nominal | 22.2 | 15,540 | 1,813 Hz | 10,878 |
| 6S full | 25.2 | 17,640 | 2,058 Hz | 12,348 |
A 14-pole rotor has 7 pole pairs, so every turn of the shaft is 7 electrical cycles, and a six-step ESC switches the phases 42 times per turn.
About the 3D model
A generic outrunner drawn from T-Motor’s published sizes: the 31 × 20 mm stator, 37.2 mm bell, 38.6 mm height, 5 mm shaft, 19 mm mounting circle and 12 teeth and 14 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.
