"snip....Why would I ever register the SparrowHawk?

If you want to fly with other aircraft, especially in formation flight, you
might have to. Sailplanes are already treated like poor second cousins to
the aviation community and ultralight aircraft and hang gliders are even
lower on the pecking order.

The Sparrowhawk's new category of ultralight sailplanes could fit a viable
niche, especially with a US manufacturer. But you'll probably get quicker
acceptance (and more people to tow you) if you stick an "N" number on it and
carry your pilot certificate.

The SparrowHawk straddles the border between aircraft
and ultralights

Which is exactly why you are going to have problems, especially in the US!
