9- to 10-inch long-range FPV motor
GEPRC SPEEDX2 3214
A 155 g 3214 that GEPRC made for 9- to 10-inch long-range quads on 6S; on GEPRC’s 24 V bench it pulled 4,723 g at full throttle on a Gemfan 1050 tri-blade, drawing 77.8 A.

The spin is an illustration: the model turns at 1/600 of the no-load speed, and it is a generic 3214 motor drawn from GEPRC’s published sizes, not its exact design. Thrust, current and power are GEPRC’s bench figures for the Gemfan 1050 prop at 24 V, read straight across between its throttle steps. Its data starts at 40% throttle.

What it pulls
GEPRC’s own bench test, one line per prop. Drag across the chart to move the throttle; the model above follows.
At 60% with the Gemfan 1050: 1,774 g of thrust, 18.9 A, 454 W, 3.90 g per watt.
On your quad
29.1 : 1
Thrust to weight at full throttle: four motors pull 18,892 g with the Gemfan 1050 at 24 V.
At 60% throttle they pull 7,096 g, 10.9 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
4.7 kg on a 10-inch
At 24 V it pulled 4,723 g at full throttle on a Gemfan 1050 tri-blade, drawing 77.8 A (1,867 W); on a Gemfan 9045 it pulled 3,419 g at 60.31 A.

Bench data
Redrawn from GEPRC’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-T6 aluminium alloy, CNC-machined in one piece, black with red-edged cut-outs and a five-spoke top. (GEPRC product page, GEPRC spec image, GEPRC product photo, GEPRC top view)
- Stator. 32 × 14 mm, 12N14P, with a single-strand copper winding in high-temperature enamelled wire. (GEPRC product page, GEPRC spec image)
- Magnets. N52H. (GEPRC product page, GEPRC spec image)
- Bearings. NSK/NMB, as GEPRC gives them. (GEPRC spec image)
- Base. Four M3 holes on a 19 mm circle, with 16 AWG leads 500 mm long. (GEPRC spec image, GEPRC drawing and data sheet)
How fast it spins
KV is the motor’s no-load speed per volt. With nothing on the shaft, the 860KV 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 | 12,728 | 1,485 Hz | 8,910 |
| 4S full | 16.8 | 14,448 | 1,686 Hz | 10,114 |
| 6S nominal | 22.2 | 19,092 | 2,227 Hz | 13,364 |
| 6S full | 25.2 | 21,672 | 2,528 Hz | 15,170 |
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 GEPRC’s published sizes: the 32 × 14 mm stator, 42 mm bell, 32.9 mm height, 5 mm shaft, 19 mm mounting circle and 12 teeth and 14 magnets. Anything GEPRC 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.
