I agree, but still - what could they have used that was not "build your own engine" ? They seemed to have preferred (or maybe were forced to ?) use off the shelf hardware, even if sub-optimal.
The only engines that were not hypergolic & used kerolox were those used on the Atlas rockets or on the Deltas. Not sure if they had the necessary throttling range and other characteristics. I guess now I need to find some sort of a biography from someone working on the DC-X project. :D
As for Armadillo Aerospace - their efforts were admirably and I really enjoyed watching their progress. And they did manage to get a working engine. :)
