5-inch FPV freestyle motor
Diatone Mamba TOKA 2306.5
A 23 × 6.5 mm motor for 5- and 6-inch quads, in 1650KV and 1770KV for 4S–6S and 2770KV for 3S–4S, with N52H magnets, a 5 mm prop shaft and 9 × 4 × 4 mm bearings.
- 5-inch freestyle (1770KV, 2770KV)
- 6-inch (1650KV)
- 16 × 16 mm M3 motor mounts
The spin is an illustration: the model turns at 1/600 of the no-load speed, and it is a generic 2306.5 motor drawn from Diatone’s published sizes, not its exact design. No-load speed is KV × 22.2 V, a nominal pack for this version. Diatone publishes no bench data for it.

Inside the motor
A brushless outrunner: the coils stand still in the middle and the magnets spin around them. From the top down:
- Shaft. 5 mm where the prop mounts, 4 mm inside the motor. (Diatone product page (archived))
- Magnets. N52H. (Diatone product page (archived))
- Stator. The coils are wound on a stack of thin steel laminations: 23 × 6.5 mm (2306.5). (Diatone product page (archived))
- Winding. 240 °C enamelled wire. (Diatone product page (archived))
- Bearings. 9 × 4 × 4 mm (Diatone also labels them 681ZZ). (Diatone product page (archived))
- Base. 16 × 16 mm, M3. (Diatone product page (archived))
How fast it spins
KV is the motor’s no-load speed per volt. With nothing on the shaft, the 1770KV 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.
| Battery | Volts | No-load rpm (KV × V) | Electrical frequency | ESC steps per second |
|---|---|---|---|---|
| 4S nominal | 14.8 | 26,196 | 3,056 Hz | 18,337 |
| 4S full | 16.8 | 29,736 | 3,469 Hz | 20,815 |
| 6S nominal | 22.2 | 39,294 | 4,584 Hz | 27,506 |
| 6S full | 25.2 | 44,604 | 5,204 Hz | 31,223 |
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 Diatone’s published sizes: the 23 × 6.5 mm stator, 29.8 mm bell, 5 mm shaft, 16 mm mounting circle and 12 teeth and 14 magnets. Anything Diatone 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.
