PNC-56 ref John Brohm Estes Nose Cone Reference List v10.1 Brohm calls this "PNC-56A" but I cannot find any upstream source for the "A" sufffix. The only known usage of "PNC-56" is in the instructions for the #2029 Converter, where it's cross-identified as a PN 72013. Numeric PNs for "PNC-56" are as follows: (Note that Brohm's list from ca. 2007 is not correct or up to date in all respects) 072015 : molded in black plastic, #1262 Cosmic Cobra, #2077 Sky Winder, #2130 Mach-12, #2128 Long Shot. Has separate heli blade attachment structure, molded in white or black Ref: Cosmic Cobra instructions, which (incorrectly) make it look like the NC has an integrated heli blade hub: http://www.estesrockets.com/media/instructions/001262_COSMIC_COBRA.pdf Ref: This Cosmic Cobra build page with photo showing the black NC and separate white heli hub: http://www.seed-solutions.com/gregordy/Rockets/Cobra.htm Ref: TRF thread where user 'snuggles' confirms that the Long Shot had a black nose cone and fin can: http://www.rocketryforum.com/archive/index.php/t-62733.html 072013 : molded in yellow plastic, #1950 Eliminator, #2029 Converter, #1330 Challenger II, #1995 Helio Copter Ref: Eliminator instructions http://www.estesrockets.com/media/instructions/001950_ELIMINATOR.pdf Ref: Converter instructions, where it's cross-listed as "PNC-56" https://www.estesrockets.com/media/instructions/002029_CONVERTER.pdf Ref: 1982 Estes catalog pp 28-29. Challenger II #1330 "No painting required with...yellow nose cone..." So it is evidently a PN 072013; Brohm errs by not designating it as molded in yellow. Ref: photo of Helio Copter kit with yellow NC and separate white heli blade hub posted to TRF at http://www.rocketryforum.com/showthread.php?137939-Info-on-the-Estes-PNC-56-nosecone&p=1651303#post1651303 Estes has used kit #1330 more than once: Challenger II is #1330 in 1982 catalog, Estes site has #1330 instructions for the Free Fall 060312 : chrome plated over plastic: black plastic in #2168 Metalizer, #2180 Chrome Dome Silver. Seen over white plastic with the same PN in a #1417 Astrobeam. Ref: Metalizer instructions http://www.estesrockets.com/media/instructions/002168_METALIZER.pdf 060340 : gold tone plated (black plastic?), #2181 Chrome Dome Gold Ref: Chrome Dome instructions http://www.estesrockets.com/media/instructions/002181_Chrome_Domes_Gold.pdf 072017 : molded in blue plastic, #2091 Maniac, #2443 Splendor. No PNs in Maniac instructions. Splendor is an E2X and gives PN; 2014 catalog shows it's blue and has 1.35" diam, correct for BT-56 There is a PN 303164 "NC-56 Nose Cone (4 pk)" on the Estes site showing black nose cones that look to not be identical. Discount Rocketry states on their site (2016) that the contents of PN 303164 change randomly among varaious shapes. To date we don't have any information on the variants except a photo showing 3 black + 1 blue in an old 4-pack. Physical data here was measured from a PN 060312 from a #2168 Metalizer, mass 19.0 g
