Tail heavy aircraft turn faster than nose-heavy aircraft.
With the centre of aerodynamic pressure in front of the centre of mass the wings contribute extra turning force whenever the aircraft isn't facing exactly into the airstream.
If the centre of mass is too far behind the centre of pressure the aircraft becomes unstable - continuously trying to snap around and fly backwards.
I think we're on the same page. When I wrote "unable to turn" I meant "unable to turn in a stable manner". It would exhibit what in a car we'd call "oversteer". The pilot would have to be very gentle and careful in turns, which means death in air combat.
