Stability and Control characteristics of the Early Mark Spitfires

My understanding is that a MkV is basically just a MkI but with a Merlin 45. True?

in very basic terms yes, but there were relatively significant differences, the bob weight, but even an engine change makes it a different beast, it performs differently it is loaded differently, the pilot's notes between the 2 reflect that, so I don't think it's a fair comparison at all.
