I'm creating "Japan South Terrain" for event. It will need to fly long range. So, I check Fuel Burn Time off-line. I set-up FuelBurnRateMulti 2.5 as same of MainArena.

F4U-1D could fly 5'46" by full throttle 25% fuel no wep no drop tanks.
It could fly 7'26" by Manifold presure 35. It's good for long range flight.
Next, I tested propeller pitch. I made engine speed 2000rpm down. But, F4U-1D fly 5'46" only. Engine speed didn't influence fuel burn time.
It's strange, isn't it?
