Mark: That glide ratio informationis valuable to me and gixes me some idea as to what I can expect. It seems to me if my memory serves me right that the glide ratio is lower than the 172 or the early 150/160 hp 177s(Cardinals) and very much a "Brick" compared to the 150's. The 182s & up of course have lower glide ratios with the 182's down in the 10:1 area if I remember well but since the 182's are in the 2600 to 2800 MTOW area they do not get bounced about near as much as a KR will.
