The Chaoli CL-0615-14 is the 'Race Edition' Tiny Whoop motor. These 14,800 kV coreless motors provide plenty of power to carry the camera + vtx. These motors give you a good balance of performance and battery life and are just slightly faster than the 'Fast' motors.
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)
