From 'Too Young to Die', a Kiwi Corsair pilot's memoir..
[P.233] Relating to the thread topic, while flying in Japan, on occupation duties..
"Whilst on patrol, we frequently engaged in dogfights with Australian Mustangs & found that
the Corsair had superior manoeuvrability, particularly if we employed the manoeuvring flap
setting of up to 20`which could be applied at up to 175 knots.
Under these conditions, as we tightened the turns the Mustangs would eventually flick out
& we had no trouble keeping behind them."
He adds, [P.324] Re Mustang vs Corsair..
"... - the similarity in performance was surprising, considering that the aircraft were completely the opposite in construction, although together they represented the cream of American design.
The 5-bladed 2,000hp Griffon-engine Spitfires which frequently visited our base had however
considerably higher performance than either the Mustang or Corsair..."

"When pilots of the Indian Spitfire Squadron performed aerobatics overhead, the incredible performance, & the deafening screech of the Griffon, was almost frightening."
