7- to 8-inch FPV motor
FPVCycle 2809
A 2809 motor FPVCycle sized for 7- to 8-inch props on 6S: 1300KV, 53 g with leads, N52H magnets, a hollow titanium shaft and NMB 13 × 6 × 5 mm bearings.
- 7- to 8-inch builds
- 6S (rated 6S–8S)
- 19 × 19 mm M3 motor mounts
The spin is an illustration: the model turns at 1/600 of the no-load speed, and it is a generic 2809 motor drawn from FPVCycle’s published sizes, not its exact design. No-load speed is KV × 22.2 V, a nominal pack for this version. FPVCycle publishes no bench data for it.
- Weight
- 53 g
- with 20 cm, 18 AWG leads

What you get
Sized for 7–8-inch on 6S
FPVCycle says it chose the 2809 size for its balance of magnetic flux, stator heat dissipation, efficiency and weight, and tuned 1300KV for typical 7- to 8-inch loads on 6S.

RCinPower parts
Built from RCinPower’s latest components and magnets, with FPVCycle’s changes to bell durability, bearing access, flush mounting and magnet heat dissipation.

Mixes with the 30mm motor
It replaces FPVCycle’s earlier 30mm motor, and the two can be mixed on one craft.

- Props
- FPVCycle’s favourite prop on this motor is the Gemfan 7035 tri-blade in carbon-reinforced nylon. (FPVCycle product page)
- Battery
- A 6S pack of 1800–3000 mAh with a high C rating, FPVCycle suggests; the motor is rated for 6S–8S. (FPVCycle product page)
- Frame
- M3 screws on a 19 × 19 mm pattern; the base mounts flush. (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. 7075 aluminium, with a spare sold separately. (FPVCycle product page)
- Shaft. Hollow titanium alloy with an M5 prop thread. (FPVCycle product page)
- Magnets. N52H arc magnets. (FPVCycle product page)
- Stator. 28 × 9 mm, 12N14P, 0.2 mm laminations, wound with 260 °C enamelled copper wire. (FPVCycle product page)
- Bearings. Japanese NMB, 13 × 6 × 5 mm. (FPVCycle product page)
How fast it spins
KV is the motor’s no-load speed per volt. With nothing on the shaft, the 1300KV 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 | 19,240 | 2,245 Hz | 13,468 |
| 4S full | 16.8 | 21,840 | 2,548 Hz | 15,288 |
| 6S nominal | 22.2 | 28,860 | 3,367 Hz | 20,202 |
| 6S full | 25.2 | 32,760 | 3,822 Hz | 22,932 |
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 28 × 9 mm stator, 5 mm shaft, 19 mm mounting circle and 12 teeth and 14 magnets. 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.
