New Design -- Centuri Achilles 1.00X
I *could* blame Bill "Vanel" Cooke for inspiring this one.
From the "back pages" of Centuri's Model Rocket Design Manual (1970): https://plans.rocketshoppe.com/pubs...enMRDM/MRDM.pdf Don't forget to print out the fin template page at "actual size." Also note that the nose cone shown in the plans (PDF p. 15) is actually Centuri PNC-74, *not* PNC-76. Semroc's substitute is BC-734P. Enjoy!

Not exactly a new design . . . but that came out very nicely!
Kind of a Skyhook class model, but as usual with Centuri more modern and sportier looking.

I agree, *not* actually new, but Craig considers a design "new" if it hasn't been A) seen before *or* B) RockSimmed. I suppose you could go "even bigger" and experiment with different engine (motor) sizes to get some more desireable performance, as well. Glad you liked it! Cheers,

Actually, I noticed that the RockSim file I used for the Semroc BC-734P was slightly shorter (3.0") than the original Centuri PNC-74 (3.4"). So here's the CORRECTED version of the Centuri Achilles. Cheers,
