Talbert, you're actually near one of the more active RC areas in the country. I visit Wild Bill's and Roy's hobby shops when I'm in the area and like both. There are several RC clubs in the area. You might make contact with some of them to get the best current info on resources even if you have no desire to join a club. There are several swap meets in your area as well. There are numerous "short kit" manufacturers that have either new designs of their own or they've picked up some of the old designs and are laser cutting them. Plans for many are available on Aerofred and Outerzone.uk. Glow and gasoline are alive and well in Texas. At the fly-ins there is some electric but mostly gasoline and still a fair amount of glow. Glow fuel has gotten disproportionately more expensive to the point that larger airplanes are more economical in the long run. I just go to a local FBO and buy 100LL avgas for my gasoline powered planes. It has no alcohol and doesn't varnish up if it sits in the carburetor for weeks/months like pump gas will. It's about $4-$5/gallon plus oil vs $25+ for glow fuel. Balsa USA is still cranking our kits. A club in Weatherford has a huge swap meet once a year and it's a good place to find old kits and already built planes. If you aren't familiar with the AMA website, they publish all registered fly-ins and swap meets by month and by state. Much has changed but there are still plenty of us building with wood and continuing the tradition.

Radios have changed as well. If you still have good 72MHz radios, you can put LiFePO4 (or just LiFe) batteries in the transmitters. They require computerized chargers but the smaller ones are not expensive. NiCad batteries are few and far between now but you won't miss them. Some are using NiMH for receivers but most have gone to LiFe or Lithium Polymer (LiPo). Batteries will have a whole new learning curve but they're far better than when you last flew. There are more different types and qualities of servos than imaginable. The 2.4 GHz radios are much more interference resistant than the older radios in most areas. Lots to learn but you can still be a traditional modeler.
