nice study.
table 4 is particularly impressive with the delayed pitch
Severe right wing drop which may have been an incipient spin but recovered from this immediately the stick was moved forward
Yep that's what a tramahawk will do if you try and power out.
That really didn't surprise me but there were a few others that surprised me how much they bite if you do power first.
The BTW the aircraft that doesn't recover without power is a microlight with a high C of G push engine on the back and caniars doing pitch on the front. I will defer to those that know, but I suspect it wouldn't pass certification these days.
