MPC Taurus-1 fin shape changes?
Hello All,
I have a question: Were the fins on the 15 mm diameter MPC Taurus-1 (see: http://www.rocketreviews.com/mpc-taurus-1-john-lee.html and http://www.rocketreviews.com/mpc-ta...n-lee-1114.html ) the same fins that were used on the 25 mm diameter MPC Flare Patriot (see: http://www.rocketreviews.com/mpc-fl...lace-jones.html and http://www.oldrocketplans.com/mpc/mpcR-212/mpcR-212.htm )? The reason why I ask is because the Taurus-1's fins appear to have changed. The ones shown in the two above-linked EMRR reviews look like the Flare Patriot's fins, while the Taurus-1 fins shown in this "Ye Olde Rocket Plans" scan (see: http://www.oldrocketplans.com/mpc/m...0/mpc3-0920.htm ) appear to have shorter root-to-tip spans, as well as a more pronounced difference between their root chords and tip chords. My only guess is that late in MPC's model rocket-production era, they might have switched to using Flare Patriot fins in the Taurus-1 kits as well, as they used up their kit parts inventory to make the last few production runs of kits. Also: If anyone has the MPC injection-molded plastic detail parts that were included in the Taurus-1 kit and in other MPC/AVI rocket kits (Quest also offered these plastic parts during their early years, in the early 1990s), Sirius Rocketry www.siriusrocketry.com could reproduce them in resin (if they could borrow a set of the parts) as part of their "Moldin' Oldies" product line, which includes resin duplicates of old Centuri and Estes plastic nose cones and plastic transition sections. Many thanks in advance to anyone who can help.

I think the camera is playing tricks on you. The fins on my Taurus-1 are the same as the posted plans. Mine is an original from back in the day.
I also printed out both sets of fins, the Flare patriot fins are quite a bit larger and would look enormous on the Taurus-1. They have a 1.75" span vs. 1 .125 and a root of 1.5" vs. 1.125.
