I've never flown a real Spit, but clocked up 9 hours in an Australian Supermarine Mk.26 80% scale replica.
Some lengthy conversations afterwards with colleagues with 3/4 figure hour Spitfire time led me to conclude that it handled very like a real Spit, but flew at a completely different set of numbers. (Basically halve everything, half the climb rate, half the level flight speed, but also halve the take-off and landing distances was my conclusion).
