Centuri's "catalogs" (newspapers) were better, their kits were better, they had composite technology from Enerjet, they advertised in Boys Life (as far as I remember)... yet Estes won? How? :confused2:
Which one was "better" was completely subjective. Certainly, Centuri had a more cohesive graphics presentation than Estes in the early days, but not by a significant amount. Centuri did have a style, as exemplified by roll patterns and fin planforms, that may have been more aesthetically pleasing to some than Estes' round-nose styles. But a look at the 1967 and 68 catalogs of each shows not too much difference in product line; Estes had a nice scale line and a futuristic line that Centuri didn't have until later. Estes offered more scientific merchandise (slide rules, scales, drafting equipment, AltiScope), and rocket info (free in the catalog, and available for purchase as tech reports). Camroc was available, and later, Cineroc.
Centuri had Mini-Max (and later, Enerjet), but the market was 12-16 year-olds, who had limited finances, and limited field choices (not as limited as now, but it was still difficult for kids in populous places to find places to fly bigger rockets to well over 1200').
*Both* Estes and Centuri advertised in Boys Life (and in Popular Mechanics, Popular Science, etc).
Estes won because they had the technology (they made Centuri's engines for most of its run) and they had the history. I.e, they were Coke vs Centuri's Pepsi. A significant portion of the country likes Pepsi better, but Coke still comes out in front over all.
Damon sunk its money into both Estes (in 1969) and Centuri (in 1970) (hmm. imagine General Motors buying both Coke and Pepsi in the 1940's!). By 1973, the fervor over the moon landings had ended, capital was tight, and anything you saw between the two companies after that were influenced probably by the fact that Estes had land and infrastructure, while Centuri was (if I've read the histories correctly) mostly marketing and leased warehousing, so when Damon decided to consolidate the two, it was probably a no-brainer that they slowly folded Centuri's operations into Penrose over the next ten years.
