7-inch long-range FPV motor
FlyFish Flash 2806.5
A 7-inch long-range motor: 28 × 6.5 mm stator in a one-piece 7075 bell, 48 g with 250 mm leads, and 2,171 g of pull per motor on a GF 7042 on FlyFishRC’s 24 V bench (1350KV).

The spin is an illustration: the model turns at 1/600 of the no-load speed, and it is a generic 2806.5 motor drawn from FlyFish’s published sizes, not its exact design. Thrust, current and power are FlyFish’s bench figures for the GF 7042 prop at 24 V, read straight across between its throttle steps. Its data starts at 50% throttle.

What it pulls
FlyFish’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 7042: 1,125 g of thrust, 14.0 A, 336 W, 3.35 g per watt.
On your quad
13.4 : 1
Thrust to weight at full throttle: four motors pull 8,685 g with the GF 7042 at 24 V.
At 60% throttle they pull 4,500 g, 6.9 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 for $23.90

What to pair it with
Our reading of FlyFish’s numbers, so your build matches what the motor was tested with.
- ESC
- FlyFishRC’s 10-second peaks at 24 V are 44.75 A (1350KV) and 59.97 A (1750KV), so the 1750KV needs a much bigger ESC. (FlyFishRC datasheet)
- Props
- At 24 V the 1350KV pulled 2,171.3 g on a GF 7042 and 2,159.2 g on an HQ J75; the 1750KV pulled 2,325.3 g and 2,357.6 g, drawing about 60 A. (FlyFishRC datasheet)
- Battery
- 6S, as FlyFishRC tested it; it rates the motor for 4S–6S. (FlyFishRC product page, FlyFishRC datasheet)
- Frame
- Four M3 holes on a 19 mm circle (19 × 19 mm); the shaft takes an M5 prop nut. A hardware set comes in the box. (FlyFishRC product page, FlyFishRC datasheet)

Bench data
Redrawn from FlyFish’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. One piece of 7075 aluminium (FlyFishRC’s Uni-Bell), φ34.6 mm, matte black. (FlyFishRC product page)
- Shaft. High-strength steel, 5 mm with an M5 thread, standing 14 mm above the bell. (FlyFishRC datasheet)
- Magnets. N52SH heat-resistant magnets. (FlyFishRC product page)
- Winding. Copper wire rated to 220 °C; 20 AWG leads, 250 mm. (FlyFishRC product page)
- Bearings. NMB. (FlyFishRC product page)
- Base. Thickened, with braces protecting the wire outlet and four M3 holes on a 19 mm circle. (FlyFishRC product page)
How fast it spins
KV is the motor’s no-load speed per volt. With nothing on the shaft, the 1350KV 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 | 19,980 | 2,331 Hz | 13,986 |
| 4S full | 16.8 | 22,680 | 2,646 Hz | 15,876 |
| 6S nominal | 22.2 | 29,970 | 3,497 Hz | 20,979 |
| 6S full | 25.2 | 34,020 | 3,969 Hz | 23,814 |
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 FlyFish’s published sizes: the 28 × 6.5 mm stator, 34.6 mm bell, 19.5 mm height, 5 mm shaft, 19 mm mounting circle and 12 teeth and 14 magnets. Anything FlyFish 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.
