If i intend to use two counter rotating brushless motors to get a more stable flight.
I will have to use 2 sets of Motor+esc. and connect them using Y-connector. BUT if i do so. i will be connecting two batteries to the Rx through my esc which in means i stand a good chance of burning my Rx (which incidentally i have a lot of experience in  Bang Head ).
I also considered using a common ESC but i dont know if this idea will work. And if it would will i have to get an esc of combined amp or the the motors will be in parallel?
My question-
HOW DO I PUT TWO MOTORS WITHOUT BURNING THE Rx?

Pratee kis right, bout you can use another strategy:
           
                       Diode IN4001
/-----------\    (+)     |\|____ 
|                | --------|/|
|                |     (-)   
|  ESC 1      | ---------------
|                |  (PWM)
|                | ---------------
\-----------/

                       Diode IN4001
/-----------\    (+)     |\|____ 
|                | --------|/|
|                |     (-)   
|  ESC 2      | ---------------
|                |  (PWM)
|                | ---------------
\-----------/


Put one IN4001 Diode in series of the Positive line of each of the ESC before they reach the Y cable. This would give kind of fail safe and provide more power. This diode is very easily available at any radio/tv parts or repair shop for over 1 Rs a piece.
