2-inch cinewhoop motor
Caddx 1303
A 5.6 g 1303 motor at 6000KV for 2-inch quads on 2S to 4S; it is the motor Caddx uses in its Gofilm 20 whoop.
- 2-inch cinewhoops such as Caddx's Gofilm 20
- 2S–4S
- 2-inch three-blade props such as Caddx's T2-2-3
The spin is an illustration: the model turns at 1/600 of the no-load speed, and it is a generic 1303 motor drawn from Caddx’s published sizes, not its exact design. No-load speed is KV × 14.8 V, a nominal pack for this version. Caddx 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. 1.5 mm. (Caddx product page)
- Stator. The coils are wound on a stack of thin steel laminations: 13 × 3.2 mm (1303). (Caddx product page)
How fast it spins
KV is the motor’s no-load speed per volt. With nothing on the shaft, the 6000KV 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 | 88,800 | 10,360 Hz | 62,160 |
| 4S full | 16.8 | 100,800 | 11,760 Hz | 70,560 |
| 6S nominal | 22.2 | 133,200 | 15,540 Hz | 93,240 |
| 6S full | 25.2 | 151,200 | 17,640 Hz | 105,840 |
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 Caddx’s published sizes: the 13 × 3.2 mm stator, 16.5 mm bell, 10.1 mm height, 1.5 mm shaft and 12 teeth and 14 magnets. Anything Caddx 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.
