The versions that got uploaded must be an older set of the files. Hopefully the latest copy can get integrated and solve the usability issues.Very nice
The DC-4 works in FS24 once the layout.json has been rebuilt but the B-24 still CTDs in FS24.
They haven't created a flight_model.cfg, just left everything in aircraft.cfg - might be the problem, but I'll stick to FS20 for now as the DC-4 has some blurry text in the cockpit, eg on the engine fire pull-handles.
The DC-4 also has very small fuel tanks - just 190 gallons, should be 1780 gallons - might be a mis-type?
I've edited the flight_model.cfg to fix, will investigate further tomorrow.
The North Star was a separate package for FSX/P3D.
For the fuel tanks and other elements - zero effort was put into making the flight model, weights, fuel burn, etc. accurate other than a generic 'heavy' feel and roughly appropriate airspeeds. Flight models are the most obnoxious part to work on so a lot of it gets copied from plane to plane and tweaked. There is lots of room for improvement for anyone who is up to it
