I don't like answering questions with a question, but, is there a RC club anywhere in your area? If so, go see those guys. One of the goals of many RC clubs is to get more people into the hobby/sport. Most clubs have someone that is designated as an instructor and can help you fly. Don't be shy about it. You don't appear to be too cocky about flying, so you will probably be accepted pretty well. There is no better way to learn about airplanes and flying than hands on experience--as long as you don't get your hand too close to the spinning prop :-). Teaching yourself is the most difficult and frustrating way to learn. Additionally, it is not very safe to fly a gas/glow fuel plane by yourself. You could hurt yourself, and others that you may not even know where around--if it gets away from you. In addition to learning to fly more easily, they can explain some of the finer points of flying that you may have over looked during your research and can go a long way in making your flying and modelling experience more satisfying. And you may even make a few new friends in the process. As a general rule, RC people are a good group.

I can't really tell you "what's wrong" with you, but, it happens to a LOT of us! Many of them can be found right here on RCU. Building airplanes does provide a great deal of enjoyment. The good thing is that you are smart enough NOT to rush out and try and fly them by yourself, so there is HOPE for you. If you are fortunate enough to find a good club, I am sure you will get to fly all your planes, and probably many more to come, in time! If it helps any, I have been in the hobby for a little over three years, and I just counted seven planes in my garage, and four are ready to fly!

Maybe someone else on here can steer you toward a good club. You are just north of Houston right?
