1S tiny whoop motor
WeBleedFPV Tree Topper 0802
An 0802 whoop motor at 32,500KV with a 1.5 mm shaft, sold by WeBleedFPV in sets of four as MoeFPV’s Treetoppers.

- Props for 1.5 mm shafts
The spin is an illustration: the model turns at 1/600 of the no-load speed, and it is a generic 0802 motor drawn from WeBleedFPV’s published sizes, not its exact design. No-load speed is KV × 3.7 V, a nominal pack for this version. WeBleedFPV publishes no bench data for it.

What you get for $42.99
Knurled shaft
WeBleedFPV knurls the shaft where it sits inside the motor so it slips less, which it says cuts down on desyncs.

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, with the part inside the motor knurled to keep it from slipping. (WeBleedFPV product page)
How fast it spins
KV is the motor’s no-load speed per volt. With nothing on the shaft, the 32500KV 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 | 481,000 | 48,100 Hz | 288,600 |
| 4S full | 16.8 | 546,000 | 54,600 Hz | 327,600 |
| 6S nominal | 22.2 | 721,500 | 72,150 Hz | 432,900 |
| 6S full | 25.2 | 819,000 | 81,900 Hz | 491,400 |
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 WeBleedFPV’s published sizes: the 8 × 2 mm stator and 1.5 mm shaft. Anything WeBleedFPV 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.
