RCinPower SmooX 1507 Plus M2

What it pulls

RCinPower’s own bench test, one line per prop. Drag across the chart to move the throttle; the model above follows.

What you get

• Single-nut prop mount

  RCinPower calls its single-nut design more precise, lighter and faster; its scale photos show the prop nut at 0.15 g against 0.54 g for two screws.

• Magnetic nut tool

  RCinPower shows a matching nut driver whose tip holds the nut by magnet, which it says makes the nut easier to use.

• 16.5 g

  16.5 g in all three spec tables; RCinPower's scale photo shows 16.50 g.

• Bench data from 3- to 5-inch props

  Gemfan 3208 and 4023 three-blades, 75 mm ducted three- and five-blades and the Gemfan 5125, with the temperature after 3 s at full throttle.

What to pair it with

Our reading of RCinPower’s numbers, so your build matches what the motor was tested with.

ESC

On 4S at full throttle the 3800KV drew 12.5–22.6 A; the 2680KV drew up to 20.3 A on 5S, and the 2080KV up to 18.9 A on 6S (Gemfan 5125, marked hot). An ESC rated for 25 A per motor covers all three. (RCinPower spec sheets)

Props

On the 3800KV at 16 V the Gemfan 3208 three-blade was the most efficient at full throttle (3.165 g/W) and the Gemfan 4023 pulled the most (983 g); the five-blade 75 mm ducted prop was the least efficient. The Gemfan 5125 runs on the 2080KV and 2680KV at the top voltage were marked hot (85 °C). (RCinPower spec sheets)

Battery

3S–4S for the 3800KV, 4S–6S for the 2680KV, 5S–6S for the 2080KV. (RCinPower spec sheets)

Frame

Four M2 screws, 12 × 12 mm. (RCinPower spec sheets)

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. 2 mm, threaded at the end for a single small prop nut, standing 8.2 mm above the bell. (RCinPower spec sheets)

How fast it spins

KV is the motor’s no-load speed per volt. With nothing on the shaft, the 3800KV 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.

A 12-pole rotor has 6 pole pairs, so every turn of the shaft is 6 electrical cycles, and a six-step ESC switches the phases 36 times per turn.

About the 3D model

A generic outrunner drawn from RCinPower’s published sizes: the 15 × 7 mm stator, 20.7 mm bell, 16.2 mm height, 2 mm shaft, 12 mm mounting circle and 9 teeth and 12 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.
