Why do Spitfires turn better than Hurricanes?!

[Sven]

I find it very difficult in the Hurri to keep up with a Spit in UP 2.01, I mainly fly HSFX 5.0 now so my memory might be off.

EDIT: I just fired it up and can get them in a stable sharp turn and find the Spit to be quicker but it is indeed very close, but that's just feelings.
You are right though that when speed drops to 200 the spit has a harder time keeping up, and I have to let the elevator go a bit to prevent falling down to the earth, whilst the Hurri can push some what further.
