Indeed, the Cobra 1500 uses the Antares fin sheet.

as posted here on YORF :

http://plans.rocketshoppe.com/estes..._Cobra-1500.pdf

Note the part # for the fin is BF-76 ( as in 1276, Antares ) .

many of the reused fin sets can be ID'd this way , as they use the part # of the eariest release, although easier to acertain on early kits with 1200,1300,etc part #s instead of the modern #s as quoted.

Here's a comparison between the two fins, for reference...

That makes it easy to clone. SEMROC has a BNC-50YP, which is their balsa equivalent to one of the plastic versions. If the model uses an 18" tube, then all that would be needed would be an EM-79, plus the launch lug and recovery parts.

And a decal...

John,

Here is the fin and the finset. If you would like the set just PM me with your address and I will mail them to you when I get back.

Unfortunately, I won't be able to get to my kit archive until the weekend (my kit directory says the kit is stored in bin #4, which naturally is buried in the farthest and lowest corner of the archive...).

If we can wait till then, I'll be happy to pull the kit and see what we have for fins.

I'll make a wager. If the kit fins do not match those from the Mean Machine by 5% I will donate a Semroc Hydra 7 to anyone you choose.

This is how mine turned out using Mean Machine patterns.

Looks like a match!

And I now realize what this design really is...
