Contact Sai uncle of rcforall he has them see here http://rcforall.co.in/product_info.php/cPath/63/products_id/472
Even indianhobbies have quadrotor combo check http://indianhobbies.com/shop/index.php?main_page=product_info&cPath=25_85&products_id=342.

Please note that the v-tail mixer based version has some challenges, as described in this thread :

http://www.rcindia.org/self-designed-diy-and-college-projects/quadrotor-build-thread/

No one on the forum has it working, so be warned before you invest in it.  People on the US forums also have trouble, and some have overcome it with their own custom built mixers (they tweaked the mixer software to work with the timing differences of multiple gyro outputs).

I saw an ARF kit at Ultimate heli (Dubai) last week

There are multiple ones, like the Parrot AR Drone (more fancy), and the Gaui 330.  Both have been discussed here before, and the Gaui one is more like it : http://www.rcindia.org/helis/gaui-330x-quad-flyer/

what is the function of gyros??
and why we have to use brushless motor???can we use toy motor???
and which rotor is very effective 3 or 2 blade???wht is the size of of whole quadrotor?

i want cheapest quadrotor...

Me too

I must say that by looking at the above questions, the project seems too ambitious for now. No offence meant, but i think you should first spend time(few days) by studying the elements involved in RC in depth before you go ahead with the project.

i have just starting to study about quadrotor....

These are answered already ("function of gyros", "brushed versus brushless", "what prop is better in general, and specifically for quad").  It is just a matter of searching with the right keywords, and the RIGHT keywords are always arrived at by trial and error !

Don't hate me for saying this ...  but this is your first day here, please do take a few days (not months as someone else suggested!) to read up on relevant topics, and I am sure you will spend your money wisely (and avoid costly regrets). Slow and steady... WINS the race

 

@Anwar uncle : Well i seem to have exaggerated the time   .I just meant that a newbie will require a month or two to acquire the knowledge and the building skills to build a quadrotor. I mean maybe im wrong  . What is you opinion on this?  Anyhow modified my comment.

Buddy you need some patients Read up first - there is more than sufficient information on the forum for each of the questions you have asked

JMO :well it's not that tough but it is . I have yet not completed mine as we got into some serious issues of stability ... and maneuverability . following Anwar sir's thread for now just to see  .

hello frendz,
can any buddy tell me minimum cost of quadrotor??

minimum cost = 10000
