The spin is an illustration: the model turns at 1/600 of the no-load speed, and it is a generic 1204 motor drawn from NewBeeDrone’s published sizes, not its exact design. Thrust, current and power are NewBeeDrone’s bench figures for the GF3020-3 prop at 4 V, read straight across between its throttle steps. Its data starts at 10% throttle.

Max thrust: 68 g; GF3020-3 prop, 4 V
Peak current: 14.1 A; full throttle
Max power: 52 W; full throttle

What it pulls

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

At 60% with the GF3020-3: 38 g of thrust, 7.5 A, 29 W, 1.30 g per watt.

On your quad

All-up weight650 g

0.4 : 1

Thrust to weight at full throttle: four motors pull 272 g with the GF3020-3 at 4 V.

At 60% throttle they pull 152 g, 0.2 times the quad’s weight.

All-up weight is the quad ready to fly, with its battery and camera. The thrust is the maker’s static bench figure; in the air it is lower.

What you get for $59.99

68 g on 1S
At full throttle on a GF3020 three-blade it pulls 68 g, drawing 14.12 A (52.05 W) as the pack sags to 3.69 V.

Bench data

Redrawn from NewBeeDrone’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. Dark grey, with six spokes and four M2 holes on a 5 mm circle in the top. (NewBeeDrone product photos, NewBeeDrone spec image)
Stator. 12 mm across and 4 mm tall with 9 slots; 12 magnet poles. (NewBeeDrone spec image)
Shaft. 1.5 mm, standing 4.9 mm above the bell. (NewBeeDrone spec image)
Leads. Three 28 AWG black silicone wires, 60 mm, with heat-shrink and a JST 1.25 three-pin plug. (NewBeeDrone spec image)

How fast it spins

KV is the motor’s no-load speed per volt. With nothing on the shaft, the 15000KV 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.

Battery	Volts	No-load rpm (KV × V)	Electrical frequency	ESC steps per second
4S nominal	14.8	222,000	22,200 Hz	133,200
4S full	16.8	252,000	25,200 Hz	151,200
6S nominal	22.2	333,000	33,300 Hz	199,800
6S full	25.2	378,000	37,800 Hz	226,800

A 12-pole rotor has 6 pole pairs, so every turn of the shaft is 6 electrical cycles, and a six-step ESC switches the phases 36 times per turn.

About the 3D model

A generic outrunner drawn from NewBeeDrone’s published sizes: the 12 × 4 mm stator, 15.3 mm bell, 11.3 mm height, 1.5 mm shaft, 9 mm mounting circle and 9 teeth and 12 magnets. Anything NewBeeDrone 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.
