What to pair it with

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

ESC

Flywoo gives max currents of 6.8 A (2750KV), 9.5 A (3750KV) and 13 A (4850KV), and pairs the motor with its GOKU F411 micro stack and 16×16 ESC. (Flywoo product page, Flywoo spec table)

Props

Flywoo tested HQ 3 × 2.5 and 3 × 3 three-blade props and the Gemfan 4 × 2 two-blade. (Flywoo 2750KV data, Flywoo 3750KV data, Flywoo 4850KV data)

Battery

Flywoo suggests 4S packs of 650–1000 mAh for all three KVs; the 2750KV is rated for 4S–6S. (Flywoo product page, Flywoo spec table)

Frame

Four M2 screws, opposite holes 12 mm apart; Flywoo names its Explorer LR frame. (Flywoo product page, Flywoo drawing)

Bench data

Redrawn from Flywoo’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), electroplated to a dark chrome. The top carries four M2 holes 5 mm apart around the shaft. (Flywoo drawing)
• Magnets. Arc magnets, 12 poles. (Flywoo product page)
• Stator. 14 mm across and 4 mm tall with 9 slots, wound with copper wire rated for very high heat. (Flywoo spec table)
• Shaft. 1.5 mm where the prop fits, 2 mm inside the motor, standing 4 mm above the bell. (Flywoo spec table)

How fast it spins

KV is the motor’s no-load speed per volt. With nothing on the shaft, the 2750KV 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 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 Flywoo’s published sizes: the 14 × 4 mm stator, 19.4 mm bell, 14.1 mm height, 1.5 mm shaft, 12 mm mounting circle and 9 teeth and 12 magnets. Anything Flywoo 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.
