If you are not in an airplane club, especially if you do not already know how to fly RC planes, you might want to check some out.
I entered zip code 77379 on http://www.modelaircraft.org/clubsearch.aspx and it returned 10 results within 25 miles.
Most AMA chartered clubs have volunteer instructors who will teach you how to operate the models safely and will teach you to fly. You will have to spend some money to join the club but the instruction is free. And, you get to meet a group of peope who like model planes.
