I think where this topic went horribly off course, and this is what eric19 was initally trying to say: in the case of the F4u-1a the fuel tanks are filled like this:
25% of gas you have half your main tank filled.
50% of gas you have 3/4 of your main tank filled.
75% of gas you have 1/4 of your wing tanks filled, your main tank is full.
100% of gas you have 100% of wing tanks filled and your main tank is full.
What he wants to do is instead of taking 50% of gas in your main tank initially, to be able to move that 50% to wing tanks.. I think is what he is trying to ask.
Which is why I am totally confused because as he pointed out - he wants to be able to move fuel around, but if you look above ^ the main fuel tank gets filled first before the wings, I think he's confusing with the wing tanks being filled before teh main tank.
Here's his comment:
thats how the F4U-1A hog is I empty the wing tanks first before anything else it turns much easier without them dang wingtanks full
Simply taking way to much fuel for such a short fight, you need to learn throttle control and take far less gas, I never take more then 75% in an F4u-1a or 100% only in a F4u-4.
Only reason I take 75% and NO drop tank in an F4u-1a is because if the main tank gets hit you run empty, I like to leave a little gas in the wing tanks just in case - in the f4u-4 you don't have that option with only one Main Tank.
