Hi John
Many and perhaps most SparrowHawk owners me included prefer to
operate under Part 103. This means no registration so the FAA has no
records of any SparrowHawk operating under Part 103. Why Part 103 and
not experimental? For several reasons - a couple being no county taxes
and no restrictions on where I can fly it in the US. Also I don't have
to fill out that yearly form the FAA now requires for experimental
aircraft. Remember my SparrowHawk is considered to be an "ultralight
vehicle" and not an aircraft.

"Windward" and "Sparrowhawk" and got multiple hits. *Alas, none in
California. *However the FAA database will give you the name and
address of every owner. *You can then send them some SM* to see if
they want to sell.
