#4 would indeed be a Fire Dart
which was first made by Action Kites
, beginning in the late '80s. There should be a label on the back of the spine too. This was the first kite to challenge the dominance of Top of the Line
's mighty Hawaiian Spin Off
for the title of Best Kite in the World and really was the first time we saw the delta sail form that we continue to use today. Link.
The others you might find some details on or adverts for by trawling through the early issues of SKQ
. Only the Pro/Am
even remotely rings a bell with me.
If you're looking to cash in these very pristine looking examples then you really need to find someone with a nasty case of nostalgia and poor self control. As things to fly, they are hopelessly outdated today. As objects to link back to the roots of our hobby, they might be considered priceless.
