iFlight XING2 2809

What it pulls

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

What you get for $37.99

• 5 mm titanium shaft

  iFlight calls it its strongest prop shaft yet. It protrudes 15 mm and carries an M5 thread.

• One-piece 7075 bell

  iFlight's Unibell, which it describes as crash resistant.

• NSK 11 × 5 × 5 bearings

  With iFlight's O-ring protecting the bearing gap.

• Curved N52H magnets

  Centre-slotted arc magnets set close to the stator. iFlight says they shorten the motor's response time.

• Wire protector, balanced

  A protector on the base guards the motor wires, and each motor is dynamically balanced.

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 at 24 V: about 26 A for the 800KV on a 9-inch tri-blade, 50 A for the 1250KV on an 8-inch tri-blade, and 62 A for the 1600KV on a 7040. (iFlight 1250KV test report, iFlight 800KV test report, iFlight 1600KV test report)

Props

iFlight tested the 1250KV with an HQ 8 × 4 × 3 (2933 g at full throttle) and a Gemfan 7040 (2092 g); the 7040 was more efficient at half throttle, 4.83 g/W against 4.50. (iFlight 1250KV test report)

Battery

6S. iFlight gives 24 V input for all three KVs. (iFlight product page)

Frame

Four M3 holes on a 19 mm circle (sold as "19 × 19"). Four M3 × 10 screws and an M5 flange nut come in the box. (iFlight product page, iFlight 1250KV 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 of 7075 aluminium (iFlight's "Unibell"), φ35.33 mm. (iFlight product page)
• Shaft. 5 mm titanium alloy with an M5 thread, protruding 15 mm. (iFlight 1250KV test report)
• Magnets. Curved, centre-slotted N52H arc magnets, 14 poles. (iFlight product page)
• Stator. 28 × 9 mm with 12 teeth, wound with single-strand copper; 18 AWG leads, 260 mm long. (iFlight product page)
• Bearings. NSK, 11 × 5 × 5 mm, with an O-ring that iFlight says protects the bearing gap. (iFlight product page)
• Base. Four M3 holes on a 19 mm circle, with a protector for the motor wires. (iFlight product page)

How fast it spins

KV is the motor’s no-load speed per volt. With nothing on the shaft, the 1250KV 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 28 × 9 mm stator, 35.33 mm bell, 21.7 mm height, 5 mm shaft, 19 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.
