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 the motor's peak current: about 35 A for the 1800KV on 6S, 43 A for the 2450KV and 50 A for the 2750KV on 4S (iFlight's highest readings, on a 6045 prop). On 5-inch props the peaks were 33 A, 40 A and 48 A. (iFlight 1800KV test report, iFlight 2450KV test report, iFlight 2750KV test report)

Props

iFlight tested a 5050, 5045, 5043, a 5.1 × 3.1 tri-blade and a 6045. On the 1800KV at 24 V the 5050 pulled the most of the 5-inch props (1613 g at full throttle) and the 5045 was the most efficient at half throttle (4.48 g/W). (iFlight 1800KV test report)

Battery

6S for the 1800KV, 4S for the 2450KV and 2750KV, the voltages iFlight tested them at. (iFlight 1800KV test report, iFlight 2450KV test report, iFlight 2750KV test report)

Frame

Four M3 holes on a 16 mm circle (the "16 × 16" pattern of 5-inch frames). iFlight says its Nazgul ECO XL5 uses the 1800KV. (iFlight product page, iFlight 1800KV 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"), φ28.49 mm. (iFlight 1800KV test report)
• Shaft. 5 mm hollow steel, protruding 13.5 mm; an M3 hex set screw holds it in the bell. (iFlight product page)
• Magnets. Curved N52H magnets, 14 poles. (iFlight 1800KV test report)
• Stator. 22 × 7 mm with 12 teeth, wound with single-strand copper; 20 AWG leads, 160 mm long. (iFlight 1800KV test report)
• Bearings. NSK, 9 × 4 × 4 mm. (iFlight 1800KV test report)
• Base. 2.5 mm thick, with four M3 holes on a 16 mm circle. (iFlight 1800KV test report)

How fast it spins

KV is the motor’s no-load speed per volt. With nothing on the shaft, the 1800KV 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 22 × 7 mm stator, 28.49 mm bell, 19.6 mm height, 5 mm shaft, 16 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.
