Congrats for your Quad
Happy to see it back to you ..
Great Indian People :-)

Aaah! A Happy ending

Shyam the damages happened to electronics could be very less or none at all. ESC s can definitely be repaired, but don't power up them before cleaning thoroughly - you can remove the wrapper and clean the circuit board with any non corrosive liquid cleaner or water itself and completely dry it . treat all the electronics in this way ( ESC , receiver , motors ..) Flight controller can also be done like this if it is one with out an LCD.
But test them after everything is completely dry..

havent yet tested the esc,i dint thought of cleaning them,as it was in rain i thought some may be damaged
