Thanks guys n thanks Roy. I enjoyed Reichmans book and did
remember his use
of the 15 as a standard for illustrating his points, thats part of my
interest in the bird, all the numbers have been worked out lol.

Question: libelle vs 15, does either have a climb advantage? And in
the run
how does the 15 compare to the libelle below 70 and above 70k ,
anyone have
knowledge? I can compare polars but thats not always real life.

I had the chance to fly a couple of ASW-15's back in the 1970's.
Eric Mozer generously allowed me to fly his 7T for a year and
a half when I was in AZ going through USAF pilot training and
A-7D schools. I have nothing but good memories about the
handling characteristics, though I did not get to race one against
other contemporary gliders.

One thing which has so far escaped this thread is that the -15 has
top and bottom dive brakes, so it definitely has an advantage in
a short field landing situation compared to a STD Cirrus (at least
one before the 2 stage dive brake mod) and maybe even the
H 201 Libelle. If you are out West with big fields and mostly clear
approaches, it may not matter. In the North-East USA where we
have smaller fields with sometimes high trees blocking the
approaches, it might become a determining factor in the choice.

I think that condition and trailer will wind up being the main driving
factors if you are considering a glider from that generation.

Good luck...
