A friend of mine has a Schweizer 1-35 and we need to find the
correct polar numbers to put into his SeeYou Mobile program.

Check which of the three models of 1-35 it is. Numbers for a "C"
that doesn't retract are different. There are very clear graphs of the
polars updated in 2002 in the latest Flight Manual. There are not
too many "A" models, so I'm not sure about that one since the Flight
Manual doesn't specify differences in the polar. See

I use the following numbers are for a "regular" 1-35 with a
retractable wheel. The numbers are good for final glides from 5 nm
out, dry @ 685# (We have low cloud bases here) I use
"SoarPilot," but a polar is a polar. Your mileage may vary given the
wide range of wing finishes I've seen on 1-35's.

53 kts -1.42 kts
82 kts -3.5 kts
109 kts -7.58

Be careful with that "stall speed" number. It can vary from 30 kts to
56 kts, depending on model, flap settings, and ballast. Check page 10
of the Flight Manual.
