 | According to the anthology: "The American Fighter" by Enzo Angelucci with Peter Bowles: Orion Books: New York: 1985: The figure for the rate of climb for the Grumman XF6F-6 was 936 m./min., or 3,070 ft./min., slightly faster than that for the F6F-5; (2,980 ft./min.); but marginally slower than that for the F6F-3; (3,100 ft./min.).

 | The XF6F-6 Hellcat prototypes were powered by a Pratt and Whitney R2800-18w powerplant and a four-bladed propeller.
 Officially its top speed was listed as 417 mph.  However,
 the prototypes were, I believe, two converted F6F-3 aircraft
 and may have had the original air speed indicators, which
 did not function properly.  These old systems consistently
 read 20 knots slower than the -3 Hellcat's actual speed.
 The top speed for the -3 is listed, for instance as 376 mph.
 Twenty knots translates to 23 mph and therefore the actual
 top speed was 399 mph.  The top speed for the -5 Hellcat is
 listed as 386 mph, but shortly into its production run, the
 -5 converted to a new and more accurate air speed system,
 which listed its tops speed as 409 mph.  If the XF6F-6 pro-
 totypes had the old airspeed system, which in all probabil-
 ity they did, then the actual top speed of these aircraft
 would have been about 440 mph.  This performance equals that
 of the F4U-C Corsair.
 
 Does anyone have information about this prototype's climb
 performance?
