im not sure if this has been posted before, but im doing it anyway, to help my wingmen out

these are all the stock flyable aircraft glidespeeds directly out of the manual

BEST GLIDE SPEED
Wildcat            100kts

Hellcat            130kts

Corsair                     140kts

P-38            160kts

M2 Zero            90kts

M5 Zero            90 kts

George            110kts

the performance specifications below are at 95% medium settings. the range includes taking off, climbing within 0-10 knots above best glide speed, up to cruise altitude at 100% throttle, and flying at 100% throttle until the tanks are dry (no external stores of any kind). i did the homework of physically flying and documenting the distances, speeds, etc. just because i wanted to know for myself at the time.

the ranges shown are one half of what youll get at cruise alt (cruise alt. according to the manual) when flying in a straight line. for example; when your A6M2 runs dry,  youll be nearly 500 miles from your base. i used half because its typically appreciated to get back home after a mission. plus, if you ARE at cruise on the way home and sputter out, you can just glide back down, and im almost completely certain youll be able to make it. (range varies if youre returning to a moving carrier)

and yes, the corsair has better range than the lightning. this is not a typo.

S!

i did neglect to state that it was with the "enable auto mixture". i was giving the specs for full throttle. i know that range is drastically increased simply by pulling throttle back to even 80%, let alone the many other variables available, but i didnt want to go through all that again. the whales, dolphins, and other points of interest were severely lacking from the the waters near the island i took off from, and i got bored of seeing the water

Max range altitude for these aircraft was generally at or below 25,000ft, give or take  a few thousand & thier best cruise speed was well below thier maximum speed for these altitudes.  

Even the ultra-long range, for its time, B-29's best economical cruising speed was 220 mph at 25,000. B-29A's  maximum speed was 357 mph at 30,000 feet feet. 

The B-24 ran at 180-215mph below 25,000 while its maximum continuous speed at 25,000 feet was 278 mph.  

The other long range heavy the B-17G was also in the 25,000ft range at 150mph while its maximum speed at 25,000 feet was 263 mph.
