nice work buddy 

thank you sudiptarc  

This is ultimate solution to those who want to use their airplane transmitter to control their robots.
Its Advantages
1.) Total isolation of two circuits, their is no special logic between Tx/Rx and DC motors, just touch and go.
2.) Separate power supply for DC motors, hence we get long time to play with it.
3.) Very easy to build, no special hardware is required except RC stuff.

if you want to have more fun remove you jugaad and make any easy small pcb using transistors which to make it drive forward and back ward , nice effort by the way ,

Thank you vineet, everybody cannot make PCBs, i want to keep it simple. but Making PCB is not a bad idea i'll definitely try, thanks for your suggestion.

Nice effort! 
Now throw in an arduino with a simple PPM encoder and you can use all the channels. A low cost relay H-Bridge would also be a good addition.

Thank you Swapnil
Relays and H Bridge along with arduino is good idea  will be upgrading very soon.
