5-inch 6S FPV motor
Hypetrain PDEVX 2306.5
A 6S motor made with pilot PDEVX: 2306.5 stator, 1985KV, 34 g, with a one-piece bell Hypetrain says makes it more durable.
- 6S builds
- 16 × 16 mm 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 Hypetrain’s published sizes, not its exact design. No-load speed is KV × 22.2 V, a nominal pack for this version. Hypetrain publishes no bench data for it.

What you get
Made for 6S
Hypetrain describes the PDEVX as a 6S motor: 1985KV on a 23 × 6.5 mm stator, rated for 3S–6S.

One-piece bell
A uni-bell design, which Hypetrain says makes the motor more durable.

Solder-free version
Also sold with an MR30 plug instead of bare leads, so it connects without soldering.

What to pair it with
Our reading of Hypetrain’s numbers, so your build matches what the motor was tested with.
- Battery
- 6S, the voltage Hypetrain built it for; it is rated for 3S–6S. (Hypetrain product page)
- Frame
- A 16 × 16 mm screw pattern and a 5 mm shaft. The standard version’s 20 AWG leads are 44 mm long, so the ESC has to sit close to the motor. (Hypetrain product page)

Full specs
| Spec | Value | Source |

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 uni-bell; replacement bells are sold separately. (Hypetrain product page, Hypetrain replacement bell page)
- Stator. 23 × 6.5 mm, 12N14P. (Hypetrain product page)
How fast it spins
KV is the motor’s no-load speed per volt. With nothing on the shaft, the 1985KV 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 | 29,378 | 3,427 Hz | 20,565 |
| 4S full | 16.8 | 33,348 | 3,891 Hz | 23,344 |
| 6S nominal | 22.2 | 44,067 | 5,141 Hz | 30,847 |
| 6S full | 25.2 | 50,022 | 5,836 Hz | 35,015 |
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 Hypetrain’s published sizes: the 23 × 6.5 mm stator, 5 mm shaft, 16 mm mounting circle and 12 teeth and 14 magnets. Anything Hypetrain 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.
