FWIW the instructions for the newly re-issued Explorer Aquarius (#7253) show the trailing edge of the fins at 3/4" from the end of the tube. https://estesrockets.com/wp-content...ER_AQUARIUS.pdf

I just got back from NC. I slit open a #7253 because I'll be building one this summer. The fins measure 3.375" x 2.675" x 3/32" thick. The grain goes longwise. Here's a scan of the (2) sheets with a 1" reference.

Just out of curiosity, I printed the old fin templates at JimZ's at normal (100%) size. They were 3 3/8 (3.375) inches by 2 11/16 (2.6875) inches. Difference of .0125". That's less than 1/64 of an inch. Shoot, now I'll have to make another clone! BTW thanks for the updated scan Jeffy!

You’re welcome. Your measurements are probably more correct than mine, but you’re right-it’s a very small difference. I don’t remember if the original #2016 included the balsa alignment cradle or not. I would have to open one of my vintage kits to see—but I won’t. The alignment cradle sure helps with all those stinkin’ tubes!
