Whoop motor
NewBeeDrone FLOW 0804 Dual Ball-Bearing
An 0804 whoop motor with two 681XZZ ball bearings and a 1 mm double step shaft, 2.85 g without wire, in 14000KV (2S), 19000KV and 25000KV.
- Whoops such as NewBeeDrone's Cockroach75, Mosquito and MosquitoXL
- 40 mm Azi or Gemfan 65mmS props
- JST 1.0 or JST 1.25 motor plugs
The spin is an illustration: the model turns at 1/600 of the no-load speed, and it is a generic 0804 motor drawn from NewBeeDrone’s published sizes, not its exact design. No-load speed is KV × 7.4 V, a nominal pack for this version. NewBeeDrone publishes no bench data for it.
- Weight
- 2.85 g
- each, without wire and plug

Inside the motor
A brushless outrunner: the coils stand still in the middle and the magnets spin around them. From the top down:
- Bell. NewBeeDrone lists 7075 aluminium alloy. Dark grey, with six spokes on the top. (NewBeeDrone product page, NewBeeDrone product photos)
- Bearings. Two 681XZZ ball bearings. (NewBeeDrone feature images)
- Shaft. 1 mm double step shaft. (NewBeeDrone product page)
- Base. A three-arm base with three screw holes. (NewBeeDrone feature images, NewBeeDrone product photos)
- Leads. 50 mm leads with a JST 1.0 plug, soldered to pads on the motor. (NewBeeDrone product page)
How fast it spins
KV is the motor’s no-load speed per volt. With nothing on the shaft, the 19000KV 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 | 281,200 | 28,120 Hz | 168,720 |
| 4S full | 16.8 | 319,200 | 31,920 Hz | 191,520 |
| 6S nominal | 22.2 | 421,800 | 42,180 Hz | 253,080 |
| 6S full | 25.2 | 478,800 | 47,880 Hz | 287,280 |
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 8 × 4 mm stator and 1 mm shaft. 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.
