First bit of advice is get a trainer, like an EFlite Apprentice, and get to a local club and learn to fly a simple fixed wing model. That will help you immensely to have some small grasp on the flying aspects. Then start building... anything that you can get your hands on that's within your skill set, and work on those skill sets, and learn more skills. Go to school, and/or take an aircraft engineering class, and learn flight dynamics, and aircraft design. The more you do the above things, the closer you'll be to your goal. The above things are all prerequisite to where you say you want to be.

Obviously you can't start with building an F-4 or F-18 and expect to be fully successful. It doesn't work like that, but start with something that might be within your grasp and that you stand a good chance of success, then build on those skills for the next project, and the next, etc.. This way you'll build a virtual library in your mind of skills, and gain experience with each one.

You have some interesting goals, and set your sites pretty high, so you must know it takes years to get to the higher levels of anything... but a person has to start somewhere.. So get with it!!

Good luck with your RC future.
