7-inch FPV racing motor
T-Motor F70 2808
T-Motor's 2808 for 7-inch SPEC racing, 1300KV for 6S–8S; on T-Motor's 24 V bench it pulls 2449 gf at full throttle on a T-Hobby C7.5x4.6.
- 7-inch SPEC racing
- 6S (rated 6S–8S)
- 7-inch props such as a 7040
The spin is an illustration: the model turns at 1/600 of the no-load speed, and it is a generic 2808 motor drawn from T-Motor’s published sizes, not its exact design. Thrust, current and power are T-Motor’s bench figures for the C7.5x4.6 prop at 24 V, read straight across between its throttle steps. Its data starts at 30% throttle.
- Max thrust
- 2,449 g
- C7.5x4.6 prop, 24 V
- Weight
- 58 g
- with leads, per T-Motor's tech specs; T-Hobby's text spec list says without
- Peak current
- 52.4 A
- full 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 C7.5x4.6: 1,433 g of thrust, 18.6 A, 0 W, 3.25 g per watt.
On your quad
15.1 : 1
Thrust to weight at full throttle: four motors pull 9,796 g with the C7.5x4.6 at 24 V.
At 60% throttle they pull 5,732 g, 8.8 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 for $29.90

Linear throttle
T-Motor says the power curve is smooth and linear and the throttle responds faster, with better efficiency and heat handling for long training and racing.

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. 33.4 mm across, black, with a grey top of six spokes that fork towards the rim, their cut edges silver. (T-Motor drawing, Ligpower (T-Motor) product page)
- Shaft. 5 mm with an M5 prop thread, standing 14.5 mm above the bell. (Ligpower (T-Motor) product page, T-Motor drawing)
- Magnets and bearings. Nickel-plated arc magnets; 694ZZ bearings; balanced to within 5 mg. (Ligpower (T-Motor) product page)
- Base. Grey, 3.2 mm thick, with four M3 holes on a 19 mm circle; 18 AWG PTFE leads, 150 mm long. (T-Motor drawing, Ligpower (T-Motor) product page)
How fast it spins
KV is the motor’s no-load speed per volt. With nothing on the shaft, the 1300KV 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 | 19,240 | 2,245 Hz | 13,468 |
| 4S full | 16.8 | 21,840 | 2,548 Hz | 15,288 |
| 6S nominal | 22.2 | 28,860 | 3,367 Hz | 20,202 |
| 6S full | 25.2 | 32,760 | 3,822 Hz | 22,932 |
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 28 × 8 mm stator, 33.4 mm bell, 21.45 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.
