DeepSpace RED LINE 3115

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 $28.90

• 4.34 kg on an HQ 11×4.5×3

  On DeepSpace’s bench it pulled 4,344 g at full throttle on an HQ 11×4.5×3 at 23.0 V, drawing 66.4 A. DeepSpace offers that thrust as power for cinematic shooting.

• One-piece CNC bell

  A unibell machined in one piece from aerospace-grade aluminium alloy, which DeepSpace says adds strength and durability.

• High-temperature wire

  A magnetic circuit DeepSpace calls high-efficiency, wound with high-temperature-resistant copper wire for long flights.

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 67.3 A peak, the full-throttle current on the HQ 10×5×3 at 23.0 V; the HQ 11×4.5×3 drew 66.4 A and the GF 1050 64.3 A. (DeepSpace spec image)

Props

DeepSpace tested three props at about 24 V: full throttle gave 4,002 g on the GF 1050, 4,106 g on the HQ 10×5×3 and 4,344 g on the HQ 11×4.5×3. It names 10 to 11-inch quads for this motor. (DeepSpace spec image)

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:

• Bell. One piece (unibell), CNC-machined from aerospace-grade aluminium alloy. (DeepSpace spec image)
• Winding. High-temperature-resistant copper wire. (DeepSpace 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 DeepSpace’s published sizes: the 31 × 15 mm stator, 38.7 mm bell, 30.2 mm height, 5 mm shaft, 19 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.
