I wondered about that. Seeing 52 hp and ultralight and ref to 2 people
in the same description set off warning bells. Oddly, a google search
of 'ultralight airplane challenger II' returns many hits with
ultralight in the title.

They may be Canadian aircraft. See:

The article implies that the Canadian CAA has a different definition of
"Ultralight" than the US's FAA.

Also, don't forget that you can take a 2 seat ultralight, or for that
matter, a 1 seat ultralight, and if it meets the 51% rule of owner assembled
work, you can register it as amateur experimental, and put N numbers on it.
It then does not have to meet the ultralight rules of 5 gallons of fuel,
weight, speed, where it can fly, training flights only, ect. Probably the
legal way to do it, anyway, in the case of 2 seat "ultralights."
