@kumarpramod,
1. Send a PM to Ravi Gupta, Aeromodelling Instructor in Lucknow. He is on this forum, though not active since long. His brother had a shop near Vivekanand Hospital. Don't know if it is still operational.
2. Locate Vortex RC online. They are in Allahabad. Contact them. They should be able to meet all your requirements.
3. There are many excellent online Indian stores now. One is known to be highly unreliable. Many others are quite good. Prices vary a fair bit, so you have to check.

There is a thread on indian LHSs (local hobby stores). One member had updated it a few months ago. See it.

Try going to Butchery ground in Cantt on a Sunday morning. You may find flyers there. Though my info about Lucknow is 5 years old.

Best of luck.

Edit: Vortex-RC.com, gauravag on this forum.
