1. Is this a rare kit?
No. Sig still produces them.
2. Is it worth building?
Absolutely!
3. How does it fly/go?
Terrific. Its smaller and faster than its bigger brothers
the Kougar and King Kobra. With a strong motor its a
rocket ship.
One note...the Kobra has a built up wing while the Kougar
and King Kobra have foam core wings.
