It was suggested to me to join a club. I'd never heard of such a thing, but I found one by typing in my zip code [link=http://www.modelaircraft.org/clubsearch.aspx]here.[/link]
My club has a trainer plane. New guys are welcome to come down, get a lesson about planes, and fly the club trainer with in instructor on a dual radio system (buddy chord).
My club is a half hour drive, and is totally worth it! I've met great people, even guys with a pilot license who have let me fly a real plane! I've made good friends, learned a lot, and have a big, SAFE place to fly whenever I want.
I don't have any experience with slo-fliers or park fliers, so can't help you out there. I do have experience flying bigger, fuel powered planes AND IT IS A TOTAL BLAST!!!!!!
I never knew I'd have so much fun!!!
