The Chaoli CL-0615-19 is a faster Tiny Whoop motor. These 19,000 kV coreless motors provide insane flight performance and drain batteries.
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
