Arpan - Welcome to RC India
I hope you noticed the suggestion of reading the beginner threads in the "Gems" list (
http://www.rcindia.org/rc-india-forum/the-rc-india-gems/). There, you will find extremely useful threads for the information you are seeking, like this one :
http://www.rcindia.org/rc-general-topics/re-glow-vs-electric/In today's world, the best skill one needs to acquire is seeking out information. After doing that, I am sure questions will arise, and that's when you seek specific help on items.
We hope to get lots of questions from you going forward
(of course, after you have done the initial reading up of the the useful information people have already posted here and else where).
