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: 37 A for the 1700KV on 6S and 43 A for the 2450KV on 4S, both on a Nazgul 5140 at full throttle. A 45 A 4-in-1 covers both. (iFlight 1700KV test report, iFlight 2450KV test report)

Props

iFlight tested both KVs with a Nazgul 5140 and a Gemfan 51466. The 51466 pulled more at full throttle on less current: 1604 g against 1401 g on the 1700KV. (iFlight 1700KV test report, iFlight 2450KV test report)

Battery

6S for the 1700KV, 4S for the 2450KV, the voltages iFlight tested them at. (iFlight 1700KV test report, iFlight 2450KV test report)

Frame

Four M3 holes on a 16 mm circle (the "16 × 16" pattern of 5-inch frames). Four M3 × 8 screws and an M5 lock nut come in the box. (iFlight product page, iFlight 1700KV 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"), φ29.5 mm; iFlight says the top and base parts are CNC-machined 6061 aluminium. (iFlight product page)
• Shaft. 5 mm hollow steel with an M5 thread, protruding 13.5 mm; an M3 hex set screw holds it. (iFlight product page)
• Magnets. Curved magnets, 14 poles. (iFlight 1700KV test report)
• Stator. 23 × 6 mm with 12 teeth, wound with single-strand copper; 20 AWG leads, 160 mm long. (iFlight product page)
• Bearings. NSK, 9 × 4 × 4 mm. (iFlight product page)
• Base. Four M3 holes on a 16 mm circle. (iFlight 1700KV test report)

How fast it spins

KV is the motor’s no-load speed per volt. With nothing on the shaft, the 1700KV 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 23 × 6 mm stator, 29.5 mm bell, 18.7 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.
