Anyone have a Pegasus 101 club (fixed gear) polar
we can look at?

Performance difference two points of max. L/D.

it seems this is from the elevator, and "taping up
the relatively large openings on both the
top and bottom surface of the elevator control attach
location, and at the base of the rudder" makes the
elevator vibration problem go away.
Also in the article take a look at
the "wing root air seals," very interesting...
I wonder how many other gliders have these
similar big air holes in the fuse-to-wing.

None that was designed after 1965.
sarcasm off

It's not only the performance that makes the PW-5 hard to sell. As a
Ka-8 replacement the performance does not matter... but it were the
many sub-standard technical solutions on the (early) PW-5 that made me
(and all of my club members) laugh.
