I am new to flying. I am looking at trying to build my own ultralight aircraft and I have a few questions. I know that medically if I wanted to make flying a career, that I would have to get a medical 3 at least. If I just stick to building the ultralight and flying it, would it hurt to check with my doc to see if flying as a private pilot is even an option before I start looking at spending the money to start in on the adventure?
