One of the obvious conclusions, besides FEJ ripping off competitor's designs, is that FEJ does absolutely no R&D other than to buy a competitor's jet, and make a cast out of it.
Then they make a few changes to linkages that are totally inadequate, and keep the same paint job as the original manufacturer! Then they call it their own jet.
So, they don't spend any money on R&D to test the jet. That keeps their costs low & profits high.
Then, they mass produce it, and put into the market at a lower cost only because they have no R&D costs. The customer ends up buying a completely untested airframe.
While the fiberglass frame of the jet isn't the direct cause of a failure/crash, the supporting bulkheads, honeycomb ribs, and mechanisms "designed" by FEJ are!
FEJ does not have any engineers; they have inept copy-cats.
