The behavior changes a bit... my definition of a bit so more of a lot in 0.25 or .23 you could over ride the physics with SAS and land upside down with parachute were as in .90 you couldn't unless you really fighted it really hard. Also talking about flipping whilst doing a gravity turn my ship usually flips after taping and i MEAN just a tap then it completely flips out despite resisting it. Also at the start someone said you needed to get something to make the changes, You don't. or at least i don't. I guess it could be operating systems if you do need it to edit it. - - - Updated - - - It's most likely that as if you had it so that it's Centre of mass was low means that it'll want to have it like that. However it would be difficult as there is a more aerodynamic place the top.
