What is everything you need for an R/C airplane?

i went to this site and found one that I liked: a href="http://www.nitroplanes.com/sah12racosa.html" rel="nofollow"http://www.nitroplanes.com/sah12racosa.h…/a it costs $88 for the air plane itself but then it has other option like the controller and batterries. so what is everything i need for it. there are some stuff in there that i do not know what they are. i have never flew rc airplanes before but i will learn with smaller ones before i get on that size. so what is a power pod because it has an option of that and FPV camera, what is that? i know what the others stuff are but what about flight simulator what is that. and i also saw this guy like measure the amount of wind or something like that. what is that called and do i need one? i will take flight lessons but what are all those things. and do they have like a motor or do they just fly with the wind because it doesnt have like a motor in the front like these; a href="http://www.nitroplanes.com/4chpthwaaibo.html" rel="nofollow"http://www.nitroplanes.com/4chpthwaaibo.…/a and what about these type of planes they have alot of different options what are those? a href="http://www.nitroplanes.com/rc70edffeldu.html" rel="nofollow"http://www.nitroplanes.com/rc70edffeldu.…/a
