Dead batterty, re calibrate esc to transmitter. new esc.

Where's the sound coming from? Can you tell?

Sounds like one of the 3 motor wires has lost connection.

sound comin from motor.

Yeah I had the problem once, check the soldering on the connections to the motor, and the ones on the battery too while your at it. even a loose connection can bounce around with the vibration of the motor. Sorry if this thread is dead, or if you already solved it lol
