5-inch FPV freestyle motor
T-Motor ITS 2306.5
A 1750KV 2306.5 for 6S freestyle, made by T-Motor with IT'S FPV; on T-Motor's 24 V bench it pulls 1678–1757 g at full throttle on 5-inch tri-blades.
- 5-inch freestyle
- 6S
- 5-inch tri-blade props; T-Motor suggests low pitch
The spin is an illustration: the model turns at 1/600 of the no-load speed, and it is a generic 2306.5 motor drawn from T-Motor’s published sizes, not its exact design. Thrust, current and power are T-Motor’s bench figures for the GF F4-3 prop at 24 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 GF F4-3: 839 g of thrust, 11.3 A, 270 W, 3.11 g per watt.
On your quad
10.8 : 1
Thrust to weight at full throttle: four motors pull 7,027 g with the GF F4-3 at 24 V.
At 60% throttle they pull 3,356 g, 5.2 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.

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), 29.3 mm across, matte olive green; seven spokes leave the hub and each forks in two, then again near the rim. (T-Motor product page, T-Motor drawing and specs)
- Shaft. 4 mm inside and 5 mm outside, with 7 mm of M5 thread; it stands 12 mm above the bell. (T-Motor drawing and specs)
- Base. Olive green, with four M3 holes on a 16 mm circle; 20 AWG leads, 150 mm long. (T-Motor product page, T-Motor drawing and specs)
How fast it spins
KV is the motor’s no-load speed per volt. With nothing on the shaft, the 1750KV 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 | 25,900 | 3,022 Hz | 18,130 |
| 4S full | 16.8 | 29,400 | 3,430 Hz | 20,580 |
| 6S nominal | 22.2 | 38,850 | 4,533 Hz | 27,195 |
| 6S full | 25.2 | 44,100 | 5,145 Hz | 30,870 |
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 23 × 6.5 mm stator, 29.3 mm bell, 18.25 mm height, 5 mm shaft, 16 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.
