It's important to remember that you will never be able to fully support yourself at first. Keep it a hobby until you have the time to devote to making it work in one swoop. Otherwise you'll find yourself juggling many different aspects of life at once, and things will get stressful. Also, when you have to work with R/C for a living, sometimes it can lose it's novelty. Things stop being so fun. On top of making and selling parts, dealing with our few select distributors (Which there aren't many of) and working on the internet, I also do work for several hobby shops in the area. We used to run races at one hobby shop, and we constantly do work selling items for another. We also do repair work for hobby shops who are swamped with repairs. If you find yourself working deals all the time, getting bogged down with other peoples problems, and worrying about cash all the time, R/C can quickly stop being fun. Remember, once you get passed the stage where all you do is worry about stuff, things will get fun again. Then theirs always that little part of you that still gets enjoyment from racing, bashing, and just having a great time. When you actually get a chance to start that nitro motor, or charge up that matched pack and tear into some dirt or pavement... suddenly it's all been worth it again.....
