Internally in the single main tank, there's 197 Imperial Gallons of fuel when full. Each non-self sealing wing tank has got 52 Imp. Gal.
That's more than 3 times the fuel load out of the Spitfires you find around the MA, so you're more affected by the great amount of fuel carried. At very low speeds, the Hog rolls quite badly to the right especially with flaps down so follow Sax's fuel drainage advice. And if in doubt, use rudder. The Corsair, unlike most other fighters, has a rudder of such power, you can flip yourself over at low speeds when torque fights you. Other planes, especially those with much torque like a 109K or Spitfire XIV, wobble insanely at low speeds rendering the rudder almost useless, much unlike the F4U which can flip on a dime. Just watch out with using too much rudder and elevator at the same time particularly with the nose high because you might just spin out.
A note is also that the F4U-1A is more agile than the F4U-1D mainly because of its more aerodynamic underwings. It lacks the bomb pylons so if you take a DT or bomb, you'll still have the pylon there which will affect every section of performance. According to Widewing's tests, you will lose some 6 mph in level flight.
