Buying motors for a whoop

Whoop motors are matched to frame size and cell count. Lower KV on more voltage, higher KV on 1S. Buy them in sets of four plus a spare; one bad motor makes the quad drift.

Check before you buy

• Size for your frame: 0802/0803 for 65 mm, 1102/1103 for 75–85 mm.
• KV for your battery: around 19,000–25,000 KV on 1S, lower on 2S.
• Plug type that matches the board, so you don't have to solder.

How many motors do I need?

Four per quad. Keep one or two spares: a crash-bent shaft is the most common whoop repair.

Is higher KV always faster?

No. Too much KV for the battery drains it quickly and runs hot. Match KV to cell count and prop size first.
