ESC caught fire right after calbrating them !! what the heck

this is my first arduino quadcopter build. after uploading the required software to arduino, it was time to calibrate the ESCs.right after caliberation was finished, i gave my motors maximum throttle using the transmitter, and the motors responded excellently by increasing RPM. i was shocked to find fire and smoke coming from the rigth ESC on the back of the quad!!! i really have no idea why did this happen. i am using a 35C 3S 2200mAh Li-Po battery. please , anyone give me a clue to what the heck might be going on!!
