This is the answer from RRHT,
In answer to your query regarding the performance of the Griffon IIB-powered Beaufighter, the performance calibration was not completed before the aircraft was written-off in a forced landing. The figures recorded up to that time were 316 mph at ground level, 329.5 mph in MS gear at 3600 feet, and 342 mph in FS gear at 17,600. These results could not be confirmed as totally accurate without further tests, which, of course, never happened.
Hope this helps.
Can any one help with the figures for the Merlin and Hercules variants?
Hi Wuzak, Chris,
Thanks for the info, its the performance that interests, but the photo is superb.
Would it have been a better bet than the other two variants if it had gone in to production?/
