Cwatters, your diagram is essentially correct except there wasn't much good aerodynamic data available, so no protections that would have helped.
I realise that but..
For me the important bit is that neutral side stick means "maintain this attitude". eg It's not necessary to hold in back stick to keep the nose up once it's up.
What does the equivalent diagram look like for other aircraft? Do you have to hold the stick back to maintain a nose high attitude or will neutral stick do it?
