It's an unfortunate fact of life that most gyroplanes without N-numbers are not Part 103-legal, even if their owners claim they are. Almost all of these machines are too heavy and too fast. I have no sympathy for such pilots - to put it bluntly, they are not only illegal, they are also unethical! The reason is really quite simple. A legal ultralight pilot must accept limitations on their machine and where and how they can fly it to be legal. That's the "price" they pay to operate under Part 103. Legitimate Experimental pilots have sweated bullets to get their Private or Recreational ticket - that is the "price" they pay! The over-weight machines want the best of both worlds without paying any "price" at all and they are an insult to everyone who tries to follow the rules. They will always have endless, pious rationalizations for what they do, but the fact is they have the moral standing of someone who poaches game out of season or shoplifts from a candy store!

I have flown ultralights since 1981 and they have always been legal, both in terms of performance, airframe specifications, and how they are flown. Back in those days a legal machine could weigh no more than 155 pounds, so I have no sympathy for those who cannot obey the 254 pound weight limit. The gyroplanes you see on this system can all be legally flown in some specific configuration, which I will specify if it isn't obvious. If you don't see your favorite "ultralight" here, it's probably because I don't think it's legal. If the designer or manufacturer can prove I'm wrong, I'll be more than pleased to add it to the list.
