Does anybody know where to get 22.2v 2600mah 25c 6cell lipo battery for Trex 500 heli in India...?

On the lighter side...

Yes. You can get it at your home in India through HK 

Not 2600 mAh but 2500 mAh

You can consider  2 x 3 S 2600 MAH battery packs  in series .
I have found it a more economical way  than using   a single 6 S  as in the event of 1 pack failing  you have to replace only  a  3 S pack  rather  than replace the whole 6 S.

Align LIPOs have NOT worked well for me (and others I know).  Although I am sort of a self-admitted Align fan boy (I LOVE most of their other products), this needs to be said aloud and clear !

you can get 2450mah at RcBazaar.

You can get it on www.nex-robotics.com. They have 22.5v lithium polymer batteries but they are expensive...

Hi Guys. This is my first time and i am building my own Quadcopter. It would great help if anyone can guide me where i can purchase FS 9Ch TH9X 2.4GHz TX/RX online in India who is reliable and genuine. I am in great need as i am unable to find any. Moreover any suggestions on TX/RX purchases is highly appreciated. Would like to go for 9Ch to 16Ch TX/RX. Budget upto 15K. Guide me through this.

If your budget is 15k then the best tx to get is the Taranis Qx7. It doesn't come with an rx though. You can buy it separately though.

Bro believe me th9x is a bad radio , Avionic or frsky is better than Turnigy or Flysky . I have that radio or it was a bad decision for me. I have an Avionic rcb6i and it was my first radio , it's been 3-4 years and it's still pretty good except a bit rusty screws. Frsky is the best Avionic is also good. Buy an frsky bro
And in the turn of channels ,you probably won't need 9 channels in your life , let away 16. I have done very pro applications with a radio and it hasn't gone more than 7 channels. The 16 channel radios are actually for scale models etc which has a lot of functions. Buy the Frsky taranis Qx7 as rcrcnithesh told.  You can buy it from fellow rc members in the for sale forum that are used. And in terms of used things in rc , these things don't get damaged easily. Especially radios they last quite long , even decades. For 15 k , it's better you buy used stuff. And for the controller, kk2 boards are better for you. As long as you don't use fpv or things like gps etc , it can stand less than 15k
