Stability and Control characteristics of the Early Mark Spitfires

[Crumpp]

The very first onset is referred to as the the "Buzz" or the "Tickle"

Right, which has what to do with the fact some airplanes have higher energy stall warning's including buzz than others?

Also, what does that have to do with the ability of a pilot to precisely fly to the nibble and precisely back off to smooth air in order to maximize his aircraft's turn performance?
