RE: DC-3 maximum range?
You are correct, the default DC-3 does not have anywhere close to the range that it is supposed to. It also does not matter what you do with the throttle/prop/mixture settings....you're still going to get wet crossing the Atlantic.
I believe the problem lies in either the fuel consumption rate or the fuel tank quantity/capacity. I suspect it is the fuel burn rate, but since I don't have a copy of the DC-3 manual (only have the checklist) I can't confirm this or determine what it should be. If anyone knows what the burn rate should be, please let us know.
