2–3-inch toothpick motor
Flywoo ROBO 1202.5
A 3.8 g motor for 2- and 3-inch ultralight builds on 1S or 2S; on Flywoo's 7.4 V bench it pulls 223–227 g with 65 mm props.

The spin is an illustration: the model turns at 1/600 of the no-load speed, and it is a generic 1202.5 motor drawn from Flywoo’s published sizes, not its exact design. Thrust, current and power are Flywoo’s bench figures for the HQ T65R prop at 7.4 V, read straight across between its throttle steps. Its data starts at 50% throttle.

What it pulls
Flywoo’s own bench test, one line per prop. Drag across the chart to move the throttle; the model above follows.
At 60% with the HQ T65R: 117 g of thrust, 5.2 A, 38 W, 3.26 g per watt.
On your quad
1.4 : 1
Thrust to weight at full throttle: four motors pull 908 g with the HQ T65R at 7.4 V.
At 60% throttle they pull 466 g, 0.7 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 $12.99
Two NSK bearings
Flywoo says the dual-bearing design holds the shaft steadier, with less noise and vibration.

Bench data
Redrawn from Flywoo’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. Gold on the side, with a purple and gold top and a purple base. Four M2 holes, 5 mm apart, in the top. (Flywoo product photo)
- Bearings. Two NSK bearings. (Flywoo product page)
- Stator. 12 mm across and 2.5 mm tall. (Flywoo product page)
- Leads. 150 mm, without a plug. (Flywoo product page)
How fast it spins
KV is the motor’s no-load speed per volt. With nothing on the shaft, the 11500KV 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 | 170,200 | 17,020 Hz | 102,120 |
| 4S full | 16.8 | 193,200 | 19,320 Hz | 115,920 |
| 6S nominal | 22.2 | 255,300 | 25,530 Hz | 153,180 |
| 6S full | 25.2 | 289,800 | 28,980 Hz | 173,880 |
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 Flywoo’s published sizes: the 12 × 2.5 mm stator, 15.86 mm bell, 9 mm height, 1.6 mm shaft and 9 mm mounting circle. Anything Flywoo 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.
