3.5-inch 6S FPV motor
BetaFPV LAVA 2006
A 22.2 g T-mount 2006 for 6S 3.5-inch quads such as BetaFPV's Pavo35: 1013 g of thrust per motor at full throttle on a Gemfan D90S three-blade on BetaFPV's 24 V bench.

The spin is an illustration: the model turns at 1/600 of the no-load speed, and it is a generic 2006 motor drawn from BetaFPV’s published sizes, not its exact design. Thrust, current and power are BetaFPV’s bench figures for the GF-D90S-3B prop at 24 V, read straight across between its throttle steps. Its data starts at 30% throttle.

What it pulls
BetaFPV’s own bench test, one line per prop. Drag across the chart to move the throttle; the model above follows.
At 60% with the GF-D90S-3B: 403 g of thrust, 7.6 A, 181 W, 2.22 g per watt.
On your quad
6.2 : 1
Thrust to weight at full throttle: four motors pull 4,052 g with the GF-D90S-3B at 24 V.
At 60% throttle they pull 1,612 g, 2.5 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
1013 g on 6S
At full throttle on BetaFPV's 24 V bench it pulls 1013 g on a Gemfan D90S three-blade, drawing 23.49 A.

What to pair it with
Our reading of BetaFPV’s numbers, so your build matches what the motor was tested with.
- ESC
- BetaFPV pairs it with its F722 35A AIO V2 flight controller. On its bench a motor draws up to 23.49 A at full throttle on 24 V. (BetaFPV product page, BetaFPV drawing and bench table)
- Props
- BetaFPV recommends Gemfan D90S three-blade props (1.5 mm shaft), saying they keep prop-wash oscillation down; its bench uses them. (BetaFPV product page, BetaFPV drawing and bench table)
- Battery
- 6S, 1050–1400 mAh; BetaFPV suggests its LAVA 6S 1100 mAh pack. (BetaFPV product page)
- Frame
- Four M2 screws on a 12 mm circle; BetaFPV names its Pavo35. M2×5 and M2×7 screws come in the box. (BetaFPV product page)

Bench data
Redrawn from BetaFPV’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. Grey with orange (BetaFPV's "gray mixed orange"): orange on the cut faces of the top's windows and a thin orange ring round the bell. (BetaFPV product page, BetaFPV product photo)
- Shaft. 1.5 mm, standing 3.5 mm above the bell, with two M2 holes on a 5 mm circle for T-mount props. (BetaFPV product page, BetaFPV drawing and bench table)
- Base. Four M2 holes evenly spaced on a 12 mm circle. (BetaFPV product page, BetaFPV drawing and bench table)
- Leads. 22 AWG wires, 100 mm long. (BetaFPV product page)
How fast it spins
KV is the motor’s no-load speed per volt. With nothing on the shaft, the 2400KV 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 | 35,520 | 4,144 Hz | 24,864 |
| 4S full | 16.8 | 40,320 | 4,704 Hz | 28,224 |
| 6S nominal | 22.2 | 53,280 | 6,216 Hz | 37,296 |
| 6S full | 25.2 | 60,480 | 7,056 Hz | 42,336 |
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 BetaFPV’s published sizes: the 20 × 6 mm stator, 25.6 mm bell, 14.9 mm height, 1.5 mm shaft and 12 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.
