What you get for $38.90

• 9- to 10-inch

  Axisflying's title and images put the AZ3215 on 9- and 10-inch long-range and cinelifter drones, and it recommends HQ 9×4.5×3, Gemfan 1050-3 and Gemfan 1050X3 props.

• Bench numbers

  With the 900KV at about 24 V: 3598.2 g at 50.3 A on an HQProp 9X4.5X3 and 4806.8 g at 73.7 A on a GF 1050X3 at full throttle, reaching 61 °C and 73 °C.

What to pair it with

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

ESC

Axisflying tested with an 80 A ESC; the 900KV drew 73.7 A at full throttle on a GF 1050X3 at about 24 V. (Axisflying test data)

Props

The GF 1050X3 pulls more than the HQProp 9X4.5X3 at every step, and draws more current: 4806.8 g at 73.7 A against 3598.2 g at 50.3 A at full throttle. (Axisflying test data)

Battery

4S–6S for the 900KV and 6S for the 730KV; the bench data is at about 24 V (6S). (Axisflying product page, Axisflying test data)

Frame

Four M3 screws on a 19 mm circle. (Axisflying drawing)

Bench data

Redrawn from Axisflying’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. Black, with a spoked top. (Axisflying product photo)
• Shaft. 5 mm with an M5 thread, 10 mm of it threaded, standing 17.2 mm above the bell. (Axisflying drawing)
• Stator. 32 × 15 mm, 12 slots, with 14 arc magnets in the bell and high-temperature enamelled wire. (Axisflying product page, Axisflying spec image)

How fast it spins

KV is the motor’s no-load speed per volt. With nothing on the shaft, the 900KV 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 Axisflying’s published sizes: the 32 × 15 mm stator, 38.6 mm bell, 30.7 mm height, 5 mm shaft, 19 mm mounting circle and 12 teeth and 14 magnets. Anything Axisflying 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.
