• One-piece bell, two E-clips

  The bell is one piece, and two E-clips keep it from flying off the shaft.

What to pair it with

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

Battery

1S LiPo only. (Tiny Whoop product page (20,500KV))

Frame

Tiny Whoop lists 65–85 mm brushless whoops. It publishes no mounting pattern. (Tiny Whoop product page (20,500KV))

Props

Full specs

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, held on by two E-clips. (Tiny Whoop product page (20,500KV))
• Base. A PCB that Tiny Whoop adds to HappyModel's 802EX, so the wires can be repaired or changed. (Tiny Whoop product page (20,500KV))
• Leads. Wires ending in a JST 1.25 mm plug. (Tiny Whoop product page (20,500KV))

How fast it spins

KV is the motor’s no-load speed per volt. With nothing on the shaft, the 20500KV 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 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 Tiny Whoop’s published sizes: the 8 × 2 mm stator, 10.5 mm bell and 1 mm shaft. Anything Tiny Whoop 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.
