I don't mean to discourage you at all, but please do search the forum first before asking questions   "To know everything" is a journey...  please meet up with the local fliers in Hyderabad and they are the best resource for you.

You will see many low cost scratch built planes here with details on what material was used.  Go through those and pick one that suits you.  After you made your decision and started on the build, feel free to ask if any particular task in the build is confusing to you. 

Hope to see pictures of your plane here soon
