Here you will find more about noise suppression capacitor, though article not for rc brush motor but the principle is the same,

Same question, I wonder how crack on capcitor caused tail motor malfunction. your capacitor is not burnt, puffed or burst.. Unless the crack capacitor exposed metal parts and in touch with motor case... ..
Beats me ?
