I have the same idea when I first participate in this sport, and I got few 'Worx' brushless. Those worx motors were never be used because I didn't find properly sensored esc to drive them.

Brushless drill motors are sensored with 5 pin 'Hall' wires(the wire a sensored brushless has to connect to esc for detecting the rotor position), so they won't be powerless when startup if used in drills. However, all the model use sensored escs have 6 pin wires, so if you use the model esc, the sensored function is disabled. I found electrobikes have 5 pin sensored escs, but those esc are too large to fit in a featherweight.

If you can find proper escs, the motor would be really powerful.
