XPM,until you can get some hard info, try just the sim. in a clean config, with a speed reduction of about 1-2 kts/sec,to the stall, noting where you get any visual indications of buffet, roll/yaw etc, until it stalls. Then you can set a nominal warner at -10/15 kts, or -2-3 deg. Then work outwards with different configurations, checking where the warner operates in relation to the full stall.If you can tie in a` rate` as JF suggests, then increase your speed reduction rate to 2-3/3-4/4-5 kts/sec to fine -tune it. Should also work in steep turns ,60deg. bank @1.4 Vs.
