The Chaoli CL-0615-17 is a faster Tiny Whoop motor. These 17,500 kV coreless motors provide fast flight performance and drain a little more battery.
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
