Yes--"Wish it into the cornfield, son..." (Bill Mumy later reprised that role as an adult).
That Semroc nose cone (3.3" long) is only 0.05" longer than the 3.25" Bo-Mar nose cone.

29mm minimum diameter, or did you go for a bigger airframe?

Like the paint job. Never mind that orange/black/white were my high school colors.

Probably another reason I liked the 1970s Centuri Micron paint job.

I've always thought of the Centuri Micron as their equivalent of the Estes Mark. The plastic nose cone that Centuri retrofitted into the Micron kit in the late 1960s or early 1970s was the PNC-73. Sirius Rocketry www.siriusrocketry.com sells hollow-cast, polyurethane resin duplicates of this and other Centuri nose cones, for ST-7 and other Centuri body tubes (which Semroc has). Sirius Rocketry doesn't list all of them in the "Type C parts" listing (there's a "Type E parts" listing too, of course) in the "Moldin' Oldies" section of their website (see: http://www.siriusrocketry.biz/ishop...ype-c-parts-35/ ), but I have some of their unlisted Centuri nose cones that I ordered).

I think it was a BT-70. And the colors were orange, black and silver, not white. (My brother-in-law said I had too much white in my rockets, and I took him to heart on scratch builds/upscales.) It really hurt losing that one, but I was in no way prepared to go stomping into a field of unidentified weeds, some of which were pretty sharp, and there were no kids to hire for hazardous recovery duty.
