I'm into model aircraft, have been since a boy over 25 years ago. My advice is join a club first, the development in batteries, motors and servos in recent years has been phenomenal. You will want to ensure you get something competitive and race legal. Also there can be cheaper ways of buying these days with massive savings and if picking the right items very high quality for that price http://www.hobbyking.com/hobbyking/store/index.asp
