Are those the correct measurements?

Beats me Batman, they are the best I could find. At least for me, when I scratched one last year, close enough was good enough. I think your only alternative is ebay or a want-to-buy thread here for an original kit with the die-crushed fins.

These fins are for the Estes Mini Fat Boy, kit #2442.

I'm thinking Estes would have simply down scaled the measurements from the original BT-80 based kit to this BT-60 based kit.

Take measurements and scale it back up to what you want.

Thank you,I wanted them true to scale so the rocket will be stable in flight.

Thank you,I will.

I found the template I came up with from the oldrocketplans link. If I remember correctly, I printed the image full size, 2-up portrait on my HP printer on a Win7 machine. I measured the drawing on 1 inch graph paper with my Westcott wooden ruler. Hope this helps.

Thank you,yes that looks great.I want to thank everyone again.
