Having been involved in RC for a lot of years I've found there are many facets to consider. Flying is perhaps the major interest to most on this site. Cars, both fuel powered and electric, are a significant part of RC with almost any design you want from monster trucks to dragsters. Model yachting, both power and sail, is also a lot of fun.
I personally have been involved in model, and full size aviation, modeling for 70 years and never have tired of it. I have also run nitro powered cars. I sail model yachts as well. RC is a wide open way to spend your hobby bucks. In model aviation you have a chice of ARF (almost ready to fly) airplanes or build it yourself kits that can be quiet electric or powered by nitro or gas engines. Sailplanes can be electric or launched, with or without power, they depend on thermal air currents to stay aloft. A good way to get used to RC is boating, either sail or power. It will give you a fair start on the use of remote control.
To make a long story longer try to visit a site where different types of RC are practiced and determine which holds your interest. No matter what your decision it can only make you enjoy life a bit more. Welcome to the world of fun.
