What to pair it with

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

ESC

Rated for at least 25 A, the peak iFlight measured at full throttle on a 5030 tri-blade at 24 V. (iFlight 2500KV test report)

Props

iFlight tested it with a 5030 tri-blade (5 × 3): 385 g at half throttle and 807 g at full. Props go on the 1.5 mm shaft or bolt to the four M2 holes on a 6 mm circle. (iFlight 2500KV test report, iFlight Chinese product page)

Battery

6S. iFlight gives 24 V input. (iFlight product page)

Frame

Four M2 holes on a 12 mm circle (sold as "12 × 12"). Four M2×5 and two M2×7 screws come in the box. (iFlight product page, iFlight 2500KV test report)

Bench data

Redrawn from iFlight’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 (iFlight's "Unibell"), φ25.2 mm, with five spokes on top that fork toward the rim. (iFlight 2500KV test report)
• Prop mount. Four M2 holes on a 6 mm circle round the shaft. (iFlight Chinese product page)
• Shaft. 1.5 mm titanium alloy, protruding 4 mm. (iFlight product page)
• Magnets. Curved, centre-slotted N52H arc magnets, 14 poles. (iFlight product page)
• Stator. 18 × 6 mm with 12 teeth, wound with single-strand copper; 20 AWG leads, 160 mm long. (iFlight 2500KV test report)
• Bearings. NSK, 9 × 4 × 4 mm. (iFlight product page)
• Base. 2.5 mm thick, with four M2 holes on a 12 mm circle. (iFlight 2500KV test report)

How fast it spins

KV is the motor’s no-load speed per volt. With nothing on the shaft, the 2500KV 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 iFlight’s published sizes: the 18 × 6 mm stator, 25.2 mm bell, 16.3 mm height, 1.5 mm shaft, 12 mm mounting circle and 12 teeth and 14 magnets. Anything iFlight 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.
