they are deangerous and even the instructors might say they are a horrible aircraft.
I am one that is not a big fan of the Pa38, but anyone that says they are dangerous is talking rubbish. Personally I would rather teach on something with better coordinated controls, but most students will not have the experience to notice, and most pilots learning on them will think they are fine until they fly something like a Chippie, Bulldog or better.
