Um... I'm not sure. :) The configured empty weight is 400k lbs, but I didn't record where I got that number. I'd assume that this is really the empty weight, not including payload. YASim has a <weight> tag that can be used to provide software control over payload via the properties system, which would obviously be the right way to do this. I guess I'll assume that I did the right thing... The issue of flat-rating the engines has been nagging me, too. I strongly suspect this is at least part of the effect; does anyone have numbers that would support this? Implementing this would be really easy; analagous to the way the turbocharger waste gate gets handled in the piston engine model. It would also be a spiffy way of handling the supersonic over-speed behavior the engine model has at high speeds (the mach compression of the intake air is modelled, but the losses due to intake geometry are not).
