Hobbywing RTF 2810

What it pulls

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

What you get

• About 3.3 kg on 6S

  On Hobbywing’s 24 V bench it pulled 3279 g on an HQ 8×4×3 at 52.7 A, in line with its rated 3.3 kg.

• Cooling rotor

  Hobbywing says the RTF motors’ rotors have a cooling structure and run at full load more than 40% longer than same-size motors from other brands.

• Anti-slip prop mount

  A grooved prop mount keeps the prop from slipping.

• Tested insulation

  The coils are tested at 500 V AC, the stator is coated for 180 °C and the bearings are 685ZZ.

What to pair it with

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

ESC

Hobbywing pairs it with its XRotor FPV 65A G2 4-in-1. Peak current is 53 A for 12 s; its full-throttle run on the HQ 8×4×3 drew 52.7 A, with 12 s given for that table. (Hobbywing product page, Hobbywing datasheet, Hobbywing load tests, Hobbywing drawing)

Props

Hobbywing lists the HQ 7×3.5×3, 7×4×3 and 8×4×3. At full throttle they pulled 2485 g at 38.2 A, 2698 g at 46.2 A and 3279 g at 52.7 A. (Hobbywing product page, Hobbywing load tests)

Battery

6S LiPo. (Hobbywing product page, Hobbywing drawing)

Frame

Four M3 holes on a 19 mm circle; 18 AWG leads, 200 mm long. M3 × 10 mm screws come in the box. (Hobbywing product page, Hobbywing drawing)

Full specs

Bench data

Redrawn from Hobbywing’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. A rotor with a cooling structure and a grooved prop mount. (Hobbywing product page)
• Stator. 28 × 10 mm, silicon-steel laminations (0.2 mm by the product page) with a coating rated for 180 °C; 12 slots and 14 magnet poles. (Hobbywing datasheet, Hobbywing product page)
• Winding. Multi-strand winding of enamelled wire rated for 220 °C; the coils are tested at 500 V AC. (Hobbywing product page, Hobbywing datasheet)
• Bearings. 685ZZ. (Hobbywing datasheet)
• Shaft. 5 mm with an M5 thread, standing 15 mm above the bell. (Hobbywing datasheet, Hobbywing drawing)
• Base. Four M3 holes on a 19 mm circle; 18 AWG leads, 200 mm long. (Hobbywing product page, Hobbywing drawing)

How fast it spins

KV is the motor’s no-load speed per volt. With nothing on the shaft, the 1100KV 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 Hobbywing’s published sizes: the 28 × 10 mm stator, 34 mm bell, 23.5 mm height, 5 mm shaft, 19 mm mounting circle and 12 teeth and 14 magnets. Anything Hobbywing 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.
