7-inch long-range FPV motor
RCinPower EX2807 Plus
A 48 g 2807 in 1300KV that RCinPower tested on 6- and 7-inch props; on 6S it pulled 1,876–2,547 g per motor, the most on 7-inch three-blades.
- 7-inch long range
- 4S–6S
- 6- and 7-inch props
The spin is an illustration: the model turns at 1/600 of the no-load speed, and it is a generic 2807 motor drawn from RCinPower’s published sizes, not its exact design. Thrust, current and power are RCinPower’s bench figures for the DALProp 7056, 3-blade prop at 24 V, read straight across between its throttle steps. Its data starts at 50% throttle.

What it pulls
RCinPower’s own bench test, one line per prop. Drag across the chart to move the throttle; the model above follows.
At 60% with the DALProp 7056, 3-blade: 1,281 g of thrust, 14.1 A, 338 W, 4.61 g per watt.
On your quad
15.7 : 1
Thrust to weight at full throttle: four motors pull 10,188 g with the DALProp 7056, 3-blade at 24 V.
At 60% throttle they pull 5,122 g, 7.9 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 to pair it with
Our reading of RCinPower’s numbers, so your build matches what the motor was tested with.
- ESC
- At full throttle on 6S it drew 31.2–38.8 A on the three-blades and 41.0 A on the Gemfan 7042 two-blade (85 °C, which RCinPower marks hot). RCinPower rates it at 40 A on 5S; an ESC rated for at least 45 A per motor covers every prop tested. (RCinPower spec sheet)
- Props
- The 7-inch three-blades pulled the most: 2,547 g (DALProp 7056) and 2,480 g (Gemfan 7040) on 6S. The Gemfan 7040 three-blade was the most efficient at full throttle on 5S and 6S; the Gemfan 7042 two-blade drew the most current and ran hottest. (RCinPower spec sheet)
- Battery
- 4S–6S; RCinPower tested it on 5S and 6S. (RCinPower spec sheet)
- Frame
- Four M3 screws, opposite holes 19 mm apart. (RCinPower spec sheet)

Bench data
Redrawn from RCinPower’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:
- Shaft. 4 mm hollow; 5 mm across the thread, which stands 14.5 mm above the bell. (RCinPower spec sheet, RCinPower drawing (mirror))
- Stator. The coils are wound on a stack of thin steel laminations: 28 × 7 mm (2807). (RCinPower spec sheet)
- Base. 4 × M3 holes, opposite holes 19 mm apart (19 × 19). (RCinPower spec sheet)
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 RCinPower’s published sizes: the 28 × 7 mm stator, 33.3 mm bell, 20.7 mm height, 5 mm shaft, 19 mm mounting circle and 12 teeth and 14 magnets. Anything RCinPower 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.
