Its a great hobby with many more different aspects than people realize. If you get bored with what you are doing, it doesn't take long to find something different in the hobby to keep it fun and interesting. At first its building your first plane and then learning how to keep it in the air for longer than a few seconds. If you stop there and just fly your trainer only on calm days then yes it can get boring because the challenge is gone. Start flying in more windy conditions and start learning inverted flying and the challenge is back! Got that perfected so that you can do it without thinking and then you can look into faster more responsive low wing planes. Get a good one that has a wide speed range that can hover in the wind or crank up to 90 mph in level flight and its not likely that you will get bored for a long time. If you like building a lot, then you can look into scratch builiding from plans or come up with your own design. Use about the same measurements borrowed from other planes with your own ideas thrown in and the plane will probably fly well. If you need a change of pace you can start training newbies with their shiny new trainers. Want a different sound on the front of your plane then you can get into twins. The hobby will only get boring if you run out of ideas.
