iFlight XING2 2207

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 $20.99

• One-piece bell

  7075 aluminium machined as a single part (iFlight calls it Unibell), so the top and skirt can’t separate in a crash.

• 5 mm titanium shaft

  iFlight calls it its strongest prop shaft yet. It steps down to 4 mm inside the bearings.

• NSK bearings, sealed

  Two 9 × 4 × 4 mm NSK bearings, with an O-ring that keeps dirt out of the bearing gap.

• Curved N52H magnets

  14 centre-slotted arc magnets set close to the stator. iFlight says the small air gap makes the motor respond faster.

• Single-strand windings

  One thick strand per tooth, 50 mΩ between phases on the 1855KV.

• Balanced, with a wire guard

  Dynamically balanced at the factory; a protector on the base keeps the leads from being cut.

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: 35 A for the 1855KV on 6S, 40 A for the 2755KV on 4S. A 45 A or bigger 4-in-1 covers both with room to spare. (iFlight 1855KV test report, iFlight 2755KV test report)

Props

iFlight tested it with the Gemfan 51466 (5.1 × 4.66, three blades) and a 5.1 × 4. The 51466 pulls about 250 g more at full throttle on 6S. (iFlight 1855KV test report)

Battery

6S for the 1855KV, 4S for the 2755KV. (iFlight 1855KV test report, iFlight 2755KV test report)

Frame

Four M3 holes with opposite holes 16 mm apart (the “16 × 16” pattern of 5-inch frames). M3 × 8 screws and an M5 flange nut come in the box. (iFlight product page, iFlight 1855KV 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:

• Shaft. 5 mm titanium alloy with an M5 thread for the prop nut, protruding 13.5 mm from the bell. Inside the motor it steps down to 4 mm, the bore of the bearings. A clip at the bottom of the shaft holds the rotor on, as on every motor of this type; iFlight's sheet does not mention it.
• Bell. One piece of 7075 aluminium (iFlight's "Unibell"): the spoked top, the hub that carries the shaft, and the skirt that wraps the flux ring are machined together, which keeps the magnets round after a crash.
• Magnets. 14 curved N52H neodymium magnets, alternating north and south, glued to a steel flux ring inside the skirt. iFlight calls them "centre-slotted", which we read as a slot down the middle of each magnet.
• Stator. A stack of thin steel laminations 22 mm across and 7 mm tall with 12 teeth, each wound with a single strand of copper wire. The three phases are brought out as three 20 AWG silicone leads, 160 mm long.
• Bearings. Two NSK 9 × 4 × 4 mm ball bearings pressed into the base, one at the top of the boss and one at the bottom. An O-ring sits above the top bearing to keep dirt out of the gap.
• Base. Aluminium, 2.5 mm thick, with four M3 holes on a 16 mm circle (the “16 × 16” pattern of 5-inch frames). It ships with four M3×8 screws and an M5 flange nut.

How fast it spins

KV is the motor’s no-load speed per volt. With nothing on the shaft, the 1855KV 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

Everything with a source above is drawn to that number. The shape of the bell (its barrel profile, the coned top with its five spokes and windows, the U-notches in the rim, the gap above the base) and the M5 × 0.5 thread are scaled off iFlight's to-scale drawing and its product renders, to about ±0.2 mm. iFlight does not publish the inside of the motor, so these are typical values for a 2207 motor and are marked as estimates in the data file: stator bore 11 mm; tooth width 3 mm; 9 turns of 0.6 mm wire per tooth; air gap 0.24 mm; magnets 1.55 mm thick and 9 mm tall; flux ring 0.9 mm. The leads are drawn short. The colours follow the motor's anodised finish, a slate-navy body with teal machined edges, and there are no logos or markings: this is our drawing, not iFlight's.
