The Chaoli CL-0615-14 is the original 'Fast' Tiny Whoop motor. These 14,000 kV coreless motors provide plenty of power to carry the camera + vtx. These motors give you a good balance of performance and battery life.
These motors require more battery power than the stock Inductrix packs provide. Anything from 150-210+ mAh will provide enough juice for these motors to perform. See the Tiny Whoop battery section for some good options. Price reflected on this page is for a full 4 motor set - 2 x CW + 2 x CCW
(wire color reversed, install blue/red where black/white is on the stock setup)
