F6F-5 Speed?

Looking at a few site for the plane, the stats for Max Speed ( I take it level flight )?

Was in MPH a Km ph.. 380Mph / 611Km Ph..

I went to QMission set up and took the F6F-5 over Okinawa sunny day clear sky noon.

and gave it 100% power and kept it in level flight, I got to about 460Km and at that I have give 110% power and the most I got to was about 490Km .. now Im no expert but I kept that going for 2 or mins then back to 100% ..

Oh I see the planes load to Empty for this..

But I doubt I would get anywhere near the 380mph/611km ..

I read in another post where someone said that the F6F-5 speed was tagged about the 300mph in this sim?


How long should it take in level flight starting about 350km (ph) then pushing the power up to 100% (and an extra boost to 110%)to get to top speed 611km? I take it max speed meant level flight and not a dive!

AirSpeed is measured in two ways : True Air Speed {TAS} and Indicated Air Speed {IAS} .
Maximum speed in any aircraft varies depending on the altitude {air gets thinner higher , and different engines perform best at different altitudes} .
The Top Speed of the F6F-5 is 613km/h {380mph} at 7000m {22960ft} TAS . This would read as 419km/h {260mph} IAS , which is what the gauge shows .
Try the test at 23000ft , you should be able to get the speed you're looking for .

If you hit CRTL-F1 and cycle through to the "no cockpit" view, the guages that appear on the screen show the True Airspeed.

Also, don't forget to set the supercharger/mixture to the appropriate setting. When you start a flight in the QMB, most aircraft start with supercharger set to 1, regardless of how high yoiu start.

only the Crimea map has enviromental conditions necessary to achieve top speeds in planes in FB

fly out over the ocean (cooler) to test speeds at the rated altitudes

many planes require long periods of 110% power + WEP while overheating to get to their proper top speed , some planes cannot reach their top speed without overheating

fuel amounts doesnt affect top speed much , Radiators being open does

also pay close attention to the altitude , its quite difficult to maintain a set altitude

Make sure u are above 16,000 ft and have the second stage supercharger on... it will barely make 611kph. Actually when doing speed test on the actual F6F-5 in comparison with the F4U they found that the airspeed indicator/sensor was placed wrong on the F6F so its actual speed is higher in real life than reported. something historians miss alot. FM for F6F is pretty good with the exception of accelleration especially in a dive. Thats way off. IMO. cheers.
