Yes, the engine was not touched so it has to be xplane10. About fuel. When I put the right number, the plane did the longest real range almost twice. Did several flights and always reached the maximun range with still half deposit full. So I increased the consumption... and now the plane is doing the real range (have to try in xp10 because if with less N1 the plane have more power, then less fuel makes more miles. Have to find what is happening and inform Austin. Because maybe jet engines are better, but fuel consution is not.
