Why New Aircraft Engine Ideas Rarely Succeed

That is one flat out fantastic video. Where he doesn't go, though, is in pointing out Lyc and Conti got to where they are with the results of WWII contracts. The other two featured companies had slightly different paths into success: Austro with a real need (and real skill) to fit their own market and Rotax was literally dragged into the aviation market kicking and screaming (by Ron Shettler) but their background in Rec Vehicle production (and going into aviation at that time) gave them what it took to be able to stay the course.

Very good video. Obviously, there's only so much that can be covered in 23 minutes, but it is a fun, fast look at recent attempts to bring new certified GA powerplants to market.
Now, Paul, do the same thing for the major uncertified GA aircraft engine packages of the last 5 decades. Teething pains, support shortfalls, financial meltdowns, survivors, happy customers, folks left holding the bag, etc.
