SpeedyBee 2306.5

What it pulls

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

What you get for $19.99

• 1.55 kg of thrust on 6S

  On SpeedyBee's bench it pulled 1,551 g at full throttle on a 51466-3 prop, drawing 30.76 A (722 W) at 23.47 V.

• Made for the Master 5 V2

  SpeedyBee recommends it with its Master 5 V2 frame and F7 V3 stack, and offers PID files for that build.

• One-piece outer rotor

  SpeedyBee describes an integrated outer rotor with enhanced dynamic balance, smooth for both flying and filming.

• M5 shaft, 16 × 16 mm mount

  An M5-threaded shaft standing 13.5 mm above the bell, and four M3 holes on a 16 mm circle.

What to pair it with

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

ESC

SpeedyBee gives 30.76 A as the maximum current, the top of its own 6S bench (51466-3 prop); a 35 A or larger ESC covers it. With a BLS ESC, SpeedyBee says to set Demag Compensation to High. (SpeedyBee product page, SpeedyBee manual)

Props

SpeedyBee tested two props on 6S: the 51466-3 (1,551 g at full throttle) and the 4943.5-3 (1,472 g at 28.78 A). (SpeedyBee manual)

Battery

6S, the only voltage SpeedyBee lists. (SpeedyBee product page)

Frame

Four M3 holes on a 16 mm circle (16 × 16 mm). Five M3 × 8 mm screws and a nut come in the box. (SpeedyBee manual)

Bench data

Redrawn from SpeedyBee’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:

• Rotor. An integrated outer rotor, which SpeedyBee says enhances dynamic balance. (SpeedyBee product page)
• Top. Six spokes from a hexagonal hub, each forking in a Y near the rim (drawing and photos). (SpeedyBee manual, SpeedyBee product photo)

How fast it spins

KV is the motor’s no-load speed per volt. With nothing on the shaft, the 1800KV 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 SpeedyBee’s published sizes: the 23 × 6.5 mm stator, 28.9 mm bell, 18.4 mm height, 5 mm shaft, 16 mm mounting circle and 12 teeth and 14 magnets. Anything SpeedyBee 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.
