Stall speeds have been confirmed now at 69 mph power on, 71 mph power off, with or without speed brake. It is my contention (opinion) that since the speed brake does not effect the stall speeds, it is not producing significant lift, or the stall speeds should reduce reflecting the additional lift added. >Colin & Beverly Rainey ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
Colin, The fun is just beginning!!!!!!!!!!!!!!! Those stall speeds , I'm assuming, are indicated and a bit on the high side. My KR, at 765 pounds empty, is off and flying at just a slight bit over 50mph "indicated" and stalls at altitude at well under 60 mph indicated. My ASI seems to be fairly accurate through most of the level flight ranges. I can slow-flight with ultralights (Kolbs, Challengers, etc.) at about 60 mph indicated. I'm GUESSING my actual stall speed is probably around 55 mph. Larry Flesner
