In the F4U-1, loading 50% fuel gives you 75% fuel in the main with the wing tanks dry. Add a drop tank to get you to the fight.

If no drop tanks are available, then 75% fuel gives you 100% main and partial (1/3) wing tanks. Use the wing tanks for climbout.

If fuel is porked and the fight is more than a sector away, 100% fuel will load main and wing tanks full. Burn left tank first to compensate for left wing stalling first (SOP for F4U1 in WWII) and hope you don't get jumped too soon.

Adding a DT to 100% will give you long range bomber escort legs.

As Ren said for the spit, in the F4U you usually need to rtb at about 25% fuel. At Military power you'll get about a sector, with max cruise two sectors.

Why fly anything but hogs?

HONK!

Does not matter-I will shoot you down no matter which tank you drain first.

Nemeth, check the numbers. 25% internal fuel is NOT the same as 1 full DT. Spits without wing tanks carry 102 gallons. Spits with wing tanks carry 130. The DT is (I THINK) 30gal on the spit. DTs on a P47D-25 carries 370 internal gallons but can add another 375 in external DTs. You can't always just count "DT" as "25% of internal". Just an FYI

If u dont belive me, get into a spit 9, up 50% and a DT i belive. Once ur up auto climb @ 110 or 115 (1 of the 2) w/ the DT on then release it, the plane will start to roll on its own and the plane will start lowering the nose and stalling...

Inertia is resistance to changes in motion. More fuel means it will take your aircraft a longer time to accelerate and decellerate in the roll axis. That means that the more weight in the wings, the longer it will take to start a roll and to stop a roll. That means lower roll rate overall. In addition, weight reduces roll rate by upping the energy requirements. What you say is physically impossible.

An analogy is two men with clubs. One is swinging a three pound club, and the other is swinging a twenty pound club. The twenty pound club will have more inertia, so it will take that man longer to begin and end his swing. And at no point in the swing will his club be faster than the three pound one. Assuming that the men are of equal strength, the heavier club will be much slower.
