Hey TD can you look again at the Corsair..

According to Corky Meyer, who was Grumman test pilot in WWII and participated in the test, they showed identical performances. The slower F6F wasn’t slower at all, but have a badly placed static port, that caused lower airspeed readings.

The whole story can be read in the book “Corky Meyer’s Flight Journal”, written by Meyer himself and published by Specialty Press.

A F6F-5 vs. an earlier model F4U would be very close according to

If Corky Meyer’s memory is to be trusted, Grumman tested an F4U and Vought an F6F in the autumn of 1943, apparently later than the Boscombe Down’s report. The Hellcat’s ASI indicated 18 mph less than Corsair’s one, a difference that disappeared after relocation of static ports.

Flying side-by-side, the two fighters showed identical performances at all altitudes, with just a slight advantage for the Corsair on main blower, because of some ram air effect from the forward facing air duct in Corsair’s wing roots.

And the difference, or lack of, didn’t stop there. NACA developed spring tab assisted ailerons for the Hellcat, much improving rolling performance while reducing stick forces. With these ailerons, “Hellcat finally approached Corsair’s rolling performances”, as Meyer wrote. They were standard for the F6F-5, and were retrofitted to over 3,000 early models F6F-3. Indirectly this confirms the excellence of Corsair’s roll.

Conclusion: a side-by-side test of Il2’s Corsair and Hellcat should be very interesting, and for both types.
