1S tiny whoop racing motor
NewBeeDrone FLOW 0702 Dual Ball Bearing
A 1.58 g whoop racing motor with two ball bearings, 29000KV on 1S; NewBeeDrone measured 22.24 g at 3.8 A on a 31 mm Azi three-blade at 4 V.

The spin is an illustration: the model turns at 1/600 of the no-load speed, and it is a generic 0702 motor drawn from NewBeeDrone’s published sizes, not its exact design. No-load speed is KV × 3.7 V, a nominal pack for this version. NewBeeDrone’s bench tables for it step by thrust rather than throttle, so they are in the bench data below, not on this readout.
- Max thrust
- 22 g
- AZI 1.0 31MM-3P prop, 4 V
- Weight
- 1.58 g

- Peak current

Bench data
Redrawn from NewBeeDrone’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. 7075 aluminium in a dark bronze finish, with six spokes on the top. (NewBeeDrone product page, NewBeeDrone product photos)
- Bearings. Two ball bearings. (NewBeeDrone product page)
- Stator. 7 mm across and 2 mm tall with 9 slots; 12 magnet poles. (NewBeeDrone spec sheet)
- Leads. Three 30 AWG wires, 40 mm, with a JST 1.0 3-pin plug. (NewBeeDrone spec sheet)
How fast it spins
KV is the motor’s no-load speed per volt. With nothing on the shaft, the 29000KV 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 | 429,200 | 42,920 Hz | 257,520 |
| 4S full | 16.8 | 487,200 | 48,720 Hz | 292,320 |
| 6S nominal | 22.2 | 643,800 | 64,380 Hz | 386,280 |
| 6S full | 25.2 | 730,800 | 73,080 Hz | 438,480 |
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 NewBeeDrone’s published sizes: the 7 × 2 mm stator, 9 mm bell, 8 mm height, 1 mm shaft, 6.6 mm mounting circle and 9 teeth and 12 magnets. Anything NewBeeDrone 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.
