Hi,
I am building my 2nd multiwii quadcopter..
First was build using 4x1000kv DYS motors(FAKE CHINEsSE )
This time i want to build it nicely..nd wanted to add some never seen before features using micro servos..
I hope someone in this forum understands Multiwii circuits..can anyone help? I bought a shield before..but this time I will build it from scratch and want to understand it completely,with the use and function of each electronic component.
I have a Flysky 6chnl reciever & transmitter.
Also, I wanted to add FPV..how can i do it for under 4k Rs.??
Note- I think used motors will work..
About the frame, I want to build it myself.

You mean you want to use a pro-mini (or higher), and all wii components and 'build' the FC yourself? Your motive (to understand the circuitry) is good, but the quad won't fly very well (given the precision of nunchuk and other wii components vs. other MEMS gyros like ITG32**, MPU60**, etc.), but a senior member here Ashta sir made one and it flies great.
But the better (and safer?) bet is to buy an assembled multiwii (CRIUS Lite / SE / AIO pro, IOI Mini, NanoWii, etc.)
I've built one with a CRIUS MultiWii Lite.

Thats good. But I wanted to learn As much as I could..
Can you ask Asta sir to please help me & make me understand the circuit schematics? 

You can search for him using the search box on the top right, and drop a PM.
