Could any one provide me the urls of online indian shops from where i can buy TX and RX for my electric helis 

Many stores in our list of Indian RC outlets carry radio equipment : http://www.rcindia.org/rc-outlets-and-resellers/mega-list-of-all-rc-outlets-in-india/

Rc-for-all Chennai, RC Dhamaka Bangalore, Rotor Chennai etc all carry various TX/RX brands, just browse through their websites.

thank you.can i buy a set of identical tx and rx and use it in any electric rc heli

Typically, if you use a 6ch receiver with the appropriate radio, it would work on most electric helis.

But if you are talking about your Walkera #22E with the RX-603 receiver, then you cannot just get a standard receiver. Because, the RX-603 is a purpose built unit, with dual motor outputs (main and tail), and more importantly, it has a built in gyro !  So this is not a reciever, it is something of an "all-in-one" unit. 

You would need to get a separate gyro etc along with a standard receiver to make this work.

Dear Mr. Anwar, Thank you for the advice, guess i will have to put in the box and stuff it in some place. Are are any shops who take on such repairs in ur knowledge. Mr Anwar are u the same person who is from kolkata and has a shop for rc stuff. if so i would like to buy some cool stable heli's from u.

Nope    The person from Kolkata is someone named Arshad (or Irshad), at least that is the name that has come up in discussions with other RC flyers (I have never been in contact with this person).

You might want to try contacting him regarding your heli, as you seem to be from the east side of our country.  I will try to get his contact information for you.

would be grateful if you could get me his contact details, as he has no listed sites online.regards
