How to test if a brushless motor is good or bad

[nitrostarter]

Sounds like a good way to test to me.

Its like using a brushed motor as a generator. By spinning the output shaft, the windings then generate electricity and put it out through the power leads.

There's a guy floating around the web that took a RC boat hull. He used a Nitro motor, connected its output shaft with a collar to the output shaft of a brushed motor. He then tied the leads of the brushed motor to the power leads of a BL esc, which inturn powered a BL motor that turned the prop. So it was a nitro motor turning a DC motor making power to send through a BL esc which powered a BL motor that turned the prop....
