How about a light home-built helicopter?

I think a "morphing wing" in a human flight capable aircraft is beyond home plumbing. If you can afford that kind of design and milling equipment you can afford a larger airstrip. Unless you're thinking Fowler flaps or some such, something like a Storch or an Anatov AN-2 (which rumor has it can be had for $30,000)
