• Prop mount on the bell

  A 1.5 mm shaft end, with four M2 holes in the top of the bell (opposite holes 5 mm apart) to bolt the prop on.

• Bench data at two voltages per KV

  Two ducted props (HQProp T76, Gemfan D90) and two Gemfan 3-inch props, 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

The 3450KV drew up to 24 A at full throttle on 4S (Gemfan 4023, 85 °C); the 2450KV up to 18 A on 6S. An ESC rated for at least 25 A per motor covers both. (RCinPower spec sheets)

Props

Tested with ducted HQProp T76 and Gemfan D90 three-blades, and Gemfan 4024 two-blade and 4023 three-blade props. The two-blade 4024 was the most efficient in every test. (RCinPower spec sheets)

Battery

3S–4S for the 3450KV, 4S–6S for the 2450KV. (RCinPower spec sheets)

Frame

Four M2 screws, opposite holes 12 mm apart. (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 inside the motor, 1.5 mm where it leaves the bell, protruding 3.8 mm. (RCinPower spec sheets)
• Stator. The coils are wound on a stack of thin steel laminations: 18 × 4 mm (1804). (RCinPower spec sheets)
• Base. 4 × M2 holes, opposite holes 12 mm apart (12 × 12); the bell's top has 4 × M2 holes for the prop, opposite holes 5 mm apart. (RCinPower spec sheets)

How fast it spins

KV is the motor’s no-load speed per volt. With nothing on the shaft, the 3450KV 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 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 18 × 4 mm stator, 22.74 mm bell, 13.2 mm height, 1.5 mm shaft, 12 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.
