i thought the pony had a bad departure and some CSF issues but not a super abrupt one, also some serious lateral stability issues depending on the fuel state ...
the 190 had a quicker stall with less warning than the 109/spit but not a particularly bad stall characterized mostly by a wing drop ...
(my point is that there were warnings, less than the airframes that it was compared to, but certainly enough for pilots with experience in type to get used to and be able to manage, predict, and avoid not the "no warning stall" brown describes as that was his perception and others with more experience in type dispute his observation)
the 109 because of its slats had a very delayed and benign stall characterized by a nose drop until the speed came up again, by all accounts not much drama at all ...
the spitfire gave a lot of stall warning with tons of shudder before the stall which could be uneventful however it did have a very bad spin and that could be quite a problem if not corrected very early ...
that is what i have understood for a long time, feel free to correct or interject ...
and krusty is right there is a lot of stuff still to be learned about these things, you should all take the time to gather as much info as you are able, i am off to see Bill Gordon again tomorrow USN TBF ATO pilot ...
