Why do Spitfires turn better than Hurricanes?!

As (I think) Viper had said previously the pilot's account have to be taken with a tiny bit of grain of salt.

The thick winks of the Hurry in itself may have produced more lift but also more drag. In fact what is interesting to know for turn rates is the angle of attack needed for the turn rate and the drag it produces and finally the engine power and weight.

The engine power vs drag will overall determine the speed at which the ac will travel through air.

The lift generated vs. current airspeed and weight will determine the ability to change direction = turn rate.

The more engine power I have I may pull more angle of attack without loss of speed and the higher the lift will be. It is the lift that will cause my ac to turn. At the same time for same engine the less drag angle of attack produces the better I turn.
