2.2-inch cinewhoop motor
BetaFPV LAVA 1104
A motor for 2.2-inch cinewhoops such as BetaFPV's Pavo20 Pro II: 5.3 g, rated for up to 10.2 A and 122.5 W (7200KV), with over 230 g of thrust on Gemfan D2.2 props by BetaFPV's account.
- 2.2-inch cinewhoops such as the Pavo20 Pro II
- 3S (7200KV) or 4S (5500KV)
- Gemfan D2.2 three-blade props
The spin is an illustration: the model turns at 1/600 of the no-load speed, and it is a generic 1104 motor drawn from BetaFPV’s published sizes, not its exact design. No-load speed is KV × 11.1 V, a nominal pack for this version. BetaFPV publishes no bench data for it.

Inside the motor
A brushless outrunner: the coils stand still in the middle and the magnets spin around them. From the top down:
- Bell. Grey, with orange edges on the six spokes of the top and a thin orange ring round the side. Four M2 prop holes on a 5 mm circle. (BetaFPV product page)
- Shaft. 1.5 mm, standing 5 mm above the bell. (BetaFPV product page)
- Base. Four M2 holes on a 9 mm circle. (BetaFPV product page)
- Leads. 28 AWG: 24 mm with a JST 1.25 mm three-pin plug, or 80 mm bare (7200KV only). (BetaFPV product page)
How fast it spins
KV is the motor’s no-load speed per volt. With nothing on the shaft, the 7200KV 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 | 106,560 | 10,656 Hz | 63,936 |
| 4S full | 16.8 | 120,960 | 12,096 Hz | 72,576 |
| 6S nominal | 22.2 | 159,840 | 15,984 Hz | 95,904 |
| 6S full | 25.2 | 181,440 | 18,144 Hz | 108,864 |
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 BetaFPV’s published sizes: the 11 × 4 mm stator, 15.2 mm bell, 11 mm height, 1.5 mm shaft and 9 mm mounting circle. Anything BetaFPV 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.
