Hello,
I am a begginer at all this electronic stuff, and i know basic controlling motors etc stuff but havent ever touched RF so can anyone guide me how to go about it for making airplanes?Any begginer RFkit or anything like that would be helpful

RF stands for radio frequency...I think you mean RC which is radio control....There are some good kits and almost ready to fly RC airplanes available. There are excellent radios available as well from basic to computerized......
It depends on what you want to do and your budget.
Simply put a receiver inside the airplane receives RF from the transmitter, converts that signal to an electric signal, which is sent to the servos to convert the electric signal to mechanical force to move the controls.
If there are RC flying fields in India go there and ask lots of questions...I bet those folks would be happy to help

if you mean RC (RF is also commonly referred to as Real Flight Simulator), I would start with an electric foamy. If you want to stay in the hobby, get a 4 channel for aileron control. Something like a Hangar 9 Apprentice.

Also, get some help. Don't go it alone.
