Estes Big Bertha Damon era OpenRocket Design File
Contributed by Wolfram v.Kiparski
Comments: An Big Bertha variant (K-23 and #1948) from Estes Industries' Damon-era (1969-1989). Note the nice long motor mount tube. This variant had an engine hook, but no engine block was used. The early plastic nose cone part number was PNC-60L (two piece polystyrene cone). The later plastic nose cone had part number PNC-60MS, and even later, #71020. All of these cones were 2.5-inch long ellipsoids.
