Steve as others said; Where you are will help us help you as well as some other personal information
Have you ever done this before?
Many of us are older who started flying model airplanes when we were kids and then life, wife, kids, and job kept us away for decades, Some here have been doing this non stop since the early 50s
Do you have a specific goal?
Build and fly you own model: Buy and fly a nearly built Model? Play with glow engines? Try this with electric engines? Fly competitive in scale, stunt, combat, carrier, or just back yard fun? Got kids that you want to help you build and fly or get interested in this hobby?
Budget?
Getting your feet wet can be done relatively inexpensively if you net work with us older guys....many quite often will just give you the basic needs to get going and help teach you every thing from gluing wood together to competently flying a control line model with the fewest crash, fix, crash , fix cycles
On the other hand if you have the budget to build a fully outfitted building shop, kits, balsa, plywood, glues, weights and clamps, flat building boards, tools, covering supplies, paints and thinners and a whole lot of other hardware for the aircraft controls, fuel system, field box and on and on...
This can be real daunting and quite expensive to do ALL at once. Many of us can steer you to a basic set of needed supplies and work area that you can slowly grow if you find this to be a long range hobby / affliction / obsession...big grin
