3.5-inch cinewhoop motor
T-Motor Cine35
T-Motor's 3.5-inch cinewhoop motor for 6S: 19.6 g, IP45-sealed, and up to 883 g of thrust per motor on T-Motor's bench (Gemfan D90-3 inside an Oddity frame at about 24 V).

The spin is an illustration: the model turns at 1/600 of the no-load speed, and it is a generic 2004.6 motor drawn from T-Motor’s published sizes, not its exact design. Thrust, current and power are T-Motor’s bench figures for the D90-3 prop at 24.02 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 D90-3: 433 g of thrust, 5.7 A, 137 W, 3.17 g per watt.
On your quad
5.4 : 1
Thrust to weight at full throttle: four motors pull 3,532 g with the D90-3 at 24.02 V.
At 60% throttle they pull 1,732 g, 2.7 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 $37.90
Sealed against sand and dust
IP45, with a built-in shield that T-Motor says keeps sand, gravel and dust out, and an electrophoretic-coated core that passed a 72-hour salt-spray test.

Long flights with a camera
In T-Motor's flight tests a 680 g quad with a 1350 mAh 6S pack and a 160 g load flew 10 minutes, and a 634 g quad on a 3000 mAh pack 28 minutes without payload.

Fits many frames
The shaft screw doesn't protrude below the base, which T-Motor says lets the motor fit many frame types.

Bench data in and out of a frame
T-Motor tested three 3.5-inch props both on the open bench and inside an Oddity frame; at full throttle the thrust ran from 843 g to 883 g at 16.69–24.32 A.

What to pair it with
Our reading of T-Motor’s numbers, so your build matches what the motor was tested with.
- ESC
- T-Motor rates the peak current at 18 A for 1 s, but on its bench the motor drew up to 24.32 A at full throttle (GF DT90-5). T-Motor pairs it with its F7 45A AIO (6S) and suggests 50% startup power, auto timing and 32 kHz-by-RPM PWM with low demag compensation on BLHeli_32. (Ligpower (T-Motor) product page)
- Props
- HQ T90-3 in T-Motor's setup (868 g at 21.38 A at full throttle on the open bench). The GF D90-3 pulled 863 g and the five-blade GF DT90-5 843 g at 24.32 A. (Ligpower (T-Motor) product page)
- Battery
- 6S. In T-Motor's flight tests a 1350 mAh pack gave 15 minutes at 520 g without payload and 10 minutes at 680 g with 160 g aboard. (Ligpower (T-Motor) product page)
- Frame
- Cinewhoop X4 frames, take-off weight within 800 g and 1200 g at most, per T-Motor. Four M2 holes on a 12 mm circle. (Ligpower (T-Motor) product page, T-Motor drawing)

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. 24.69 mm across, dark grey with grooves and slots round the side; the black top has five spokes edged in copper, round a hub carrying four M2 prop screws on a 5 mm circle. (T-Motor drawing, Ligpower (T-Motor) product page)
- Shaft. 1.5 mm, standing 3 mm above the bell. (T-Motor drawing)
- Bearings. 683ZZ ball bearings, which T-Motor says are imported. (Ligpower (T-Motor) product page)
- Base. Dark grey, four M2 holes on a 12 mm circle, marked 6S; 24 AWG leads, 150 mm long. (Ligpower (T-Motor) product page, T-Motor drawing)
How fast it spins
KV is the motor’s no-load speed per volt. With nothing on the shaft, the 2100KV 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 | 31,080 | 3,626 Hz | 21,756 |
| 4S full | 16.8 | 35,280 | 4,116 Hz | 24,696 |
| 6S nominal | 22.2 | 46,620 | 5,439 Hz | 32,634 |
| 6S full | 25.2 | 52,920 | 6,174 Hz | 37,044 |
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 20 × 4.6 mm stator, 24.69 mm bell, 17.7 mm height, 1.5 mm shaft, 12 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.
