The same 3″ Estes nose cone was used in the Pro Series Patriot, the Big Daddy, the Leviathan, and the Scion. If you want one, better scramble. On YORF, Charles McGonegal writes:
The nosecone itself is no longer listed on the Estes website. Up to last week it was , just out of stock. After several emails with Christine, she said that there were none in inventory and she couldn’t get an answer if the 3″ kits would be produced again.
I have two, but one’s defective — misshapen. It’s currently residing with an unbuilt Big Daddy kit; not sure what I’m going to do with it. The other’s part of a Scion kit, which I’ll probably build more or less per design.
