What it pulls

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

What you get for $20.90

• 1,909 g on a GF51433

  On DeepSpace’s bench the 2050KV pulled 1,909.1 g at full throttle on a GF51433 at 23.4 V, drawing 44.4 A; the 1960KV pulled 1,857.7 g on the same prop.

• Titanium-alloy shaft

  A titanium-alloy shaft with a curved top, which DeepSpace says doesn’t deform after impacts and keeps nut and prop changes easy; it says a spike on the top locks the prop.

• Hollow top, curved magnets

  A hollow top cover to save weight and shed heat, and curved magnets that DeepSpace says give more power and a faster response.

• NMB bearings, reinforced base

  NMB bearings, which DeepSpace calls smooth and durable, on a reinforced base.

What to pair it with

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

ESC

DeepSpace gives a 42.4 A peak for the 1960KV and 46.8 A for the 2050KV, each the full-throttle current on the GF51466 v2 at about 23.4 V. Its highest bench current on the GF51433 was 44.4 A (2050KV). (DeepSpace spec image)

Props

DeepSpace tested two props at about 24 V: at full throttle the 1960KV pulled 1,857.7 g on the GF51433 and 1,806.3 g on the GF51466 v2, the 2050KV 1,909.1 g and 1,822.0 g. (DeepSpace spec image)

Battery

6S, for both KVs. (DeepSpace spec image)

Frame

Bench data

Redrawn from DeepSpace’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. Titanium alloy, with a curved top and an M5 thread. (DeepSpace spec image)
• Stator. 0.15 mm silicon-steel laminations wound with heat-resistant copper wire. (DeepSpace spec image)
• Bell. Hollow top cover, for less weight and better heat sinking. (DeepSpace spec image)
• Base. Reinforced. (DeepSpace spec image)

How fast it spins

KV is the motor’s no-load speed per volt. With nothing on the shaft, the 1960KV 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 DeepSpace’s published sizes: the 22 × 7.3 mm stator, 28.5 mm bell, 19.4 mm height, 5 mm shaft, 16 mm mounting circle and 12 teeth and 14 magnets. Anything DeepSpace 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.
