Well I can tell you I know of a lot of heavy ultralights that are now legally scrap because the owners didn't file paperwork in time to get them legal. The window to do this closed for ever in 2007. A bunch of early Kitfoxes were built and flown as "ultralight trainers". These were the type of planes that were well outside 103 weight and speed operating limits that Light Sport was designed to eliminate.


The three planes you have shown here, none of them, by the photos are legal. If the one was "deregistered" is has become a pumpkin. Its all over for that one. It will never get put back on the books. I seriously doubt that they can become legal as easily as you suggest, judging by the grief I have seen others go through attempting this. Have you personally done this? If you have, I would love to know where and how, in detail, did this happen.

My opinion is that all three of these examples will never fly legally again.
(Not that they ever did in the first place.)
