2–3-inch toothpick FPV motor
FPVCycle 13mm 1304
FPVCycle’s toothpick motor: a 1304 stator with 1 mm magnets, 6.9 g with long leads, on a 2 mm press-fit prop shaft, at 5000KV for 3-inch on 3S.
- 3-inch toothpicks on 2S–3S
- 2–2.5-inch on 3S–4S
- 9 mm M2 motor mounts
The spin is an illustration: the model turns at 1/600 of the no-load speed, and it is a generic 1304 motor drawn from FPVCycle’s published sizes, not its exact design. No-load speed is KV × 11.1 V, a nominal pack for this version. FPVCycle publishes no bench data for it.
- Weight
- 6.9 g
- about 6.9 g with about 85 mm of lead

What you get for $14.98
2 mm press-fit shaft
A 2 mm prop shaft, 5 mm tall, for 2 mm press-fit props, with T-mount screw holes as well; the 2 mm internal shaft runs all the way through.

6.9 g with long leads
About 6.9 g with roughly 85 mm of 27 AWG lead, on a 1304 stator with 1 mm thick magnets.

A 3-inch 3S setup
FPVCycle’s 3-inch 3S drivetrain: this motor at 5000KV, Gemfan 3016 tri-blades and a 500 mAh 3S pack, for 89–109 g all-up.

Sixth generation
FPVCycle calls it a sixth-generation design, with magnets, stator and windings refined for 2.5–3-inch props on 2S and 3S.

What to pair it with
Our reading of FPVCycle’s numbers, so your build matches what the motor was tested with.
- Props
- On 3-inch, Gemfan 3016 tri-blades, which FPVCycle highly recommends, or 3018 twin-blades with a 2 mm press-fit hole; any blades on 2–2.5-inch. (FPVCycle product page)
- Battery
- 2S–3S on 3-inch props (FPVCycle uses a 500 mAh 3S, or a 450 mAh 2S); 3S–4S on 2–2.5-inch. (FPVCycle product page)
- ESC
- On skinny-arm frames such as FPVCycle’s TP3, it suggests lowering the ESC’s startup power a notch or two from default. (FPVCycle product page)
- Frame
- 4 × M2 holes on a 9 mm circle; FPVCycle warns the small screw threads strip if over-tightened. (FPVCycle product page)

Inside the motor
A brushless outrunner: the coils stand still in the middle and the magnets spin around them. From the top down:
- Bell. One piece, 7075 aluminium, held by a C-clip at the bottom. (FPVCycle product page)
- Shaft. 2 mm, through the whole motor; 5 mm above the bell for press-fit props. (FPVCycle product page)
- Magnets. 1 mm thick. (FPVCycle product page)
- Stator. 13 × 4 mm, 0.15 mm laminations. (FPVCycle product page)
- Bearings. 5 mm size. (FPVCycle product page)
How fast it spins
KV is the motor’s no-load speed per volt. With nothing on the shaft, the 5000KV 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 | 74,000 | 8,633 Hz | 51,800 |
| 4S full | 16.8 | 84,000 | 9,800 Hz | 58,800 |
| 6S nominal | 22.2 | 111,000 | 12,950 Hz | 77,700 |
| 6S full | 25.2 | 126,000 | 14,700 Hz | 88,200 |
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 FPVCycle’s published sizes: the 13 × 4 mm stator, 2 mm shaft and 9 mm mounting circle. Anything FPVCycle 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.
