I measure 4.5" on the nose. I am measuring from the edge of the boattail to the front edge of the tube. The boattail is 1.25" long. It is a short tube---makes packing the recovery system challenging! |

Yes, in ROTW, the third flight incorportated a 34" long instrument compartment, which at 1/33 scale, would be about 1" long. The MX-774 has a rounded (ogive?) boattail that starts above the fins. Centuri changed this to a straight body with a conical (straight) boattail. BTW the G. Harry Stine drawings available from NASM (link above somewhere) are excellent with interesting details (antennas, vents, etc). |

By the way, here's the catalog "fleet group photo" showing the MX-774 in the 1972 Centuri Catalog: http://www.ninfinger.org/rockets/no...a/72cen024.html .

Great thread!! I have the Centuri kit too, and it does fly very high, even on a Quest A6-4 engine. I've been planning on building a larger scale MX-774 so as to incorporate a cluster of four engines like the real one. Thanks for all the links!

Dave, what is your tube length? I am curious to see if Centuri did change it during the production run. |

David, I think it's 4.5" too. The particular kit I had has the plastic red nosecone instead of the balsa. I didn't like the plastic one, as the tip is rounded instead of sharply pointed. I've only flown it once (at NSL-2004) as I was surprised as to how high it flew on a Quest A6-4.
