As you probably know, there is actually a lot of innovation already going on in the Experimental category. Fuel Injection, FADEC systems, advanced engine computers, terrain avoidance, synthetic vision, electronic trim, and so on. I built a Van's two-seater, and the technology I have up with me is night and day different from where we were 20 years ago, let alone 40.
Are you going the experimental / kit build route, or will you be the certified manufacturer? If it's the latter, how do you plan to navigate the FAA? I think a lot of aspirational "GA innovators" ultimately die climbing the regulatory hill.
