Airbus
So it is unfair to talk about a "fatal flaw?"
Well I didn't, maybe you should read my post again, I said (in the context of a sub fleet of 4 particular aircraft) that "had a fatal flaw as a training platform."
i.e. the lousy trim on these 4 examples killed them as an effective training platform, I didn't impy that the PA38 is inherently dangerous.
BTW, EK4457 I disagree that learning to trim with an inaccurate trimming system delivers any useful learning.
By way of comparison, the C150 or Pup are both aircraft that are challenging to trim accurately, but which do very much create better skills as a result; the difference is that they have decent trimming mechanisms that teach the pilot to develop a better feel for what s/he is doing.
