While Howard's site is GREAT for adults... try
http://www.geocities.com/fredhh/FHH_Homepage.html and look at my version beginner's guide. Its a little more oriented to a younger crowd. (still needs a little work on getting the pictures to load right. sorry... )

You'll also note that I have Howard's site linked... (Best info site.) And there's a R/C modeling webring link.
