Just a thought - what sort of speed are we talking here? AFAIK YASim doesn't 'do' trans/supersonic - might this be a factor? In the sub-sonic regime I was able to achieve some interesting high-AoA manuevours and almost a cobra & hook out of the YF-23. With the large lift area and power, combined with the "V" hstab configuration this seemed reasonable - the "v" hstab configuration should produce less drag in high-AoA than 'flat' hstabs (this might be a problem with the SU-37 I'm working on but perhaps playing with idrag might help). Then again, I might have given the 'wing' a much too high stall aoa... <rumour-mill>I've seen a quote, apparently from a high-ranking USAF? officer, who said that YF-23 technology (in terms of the airframe design/configuration philosophy) was being made use of. Didn't state where though, of course. I've also seen some drawings of a variable-sweep version of a YF-23 type recon aircraft but this might just be a case of one false rumour re-enforcing another</rumour-mill> LeeE ------------------------------------------------------------------------- Take Surveys.
