Scott,
go to this link
http://www.willswing.com/articles/Artic ... =PolarData and
you'll get the graphs for Wills wing gliders... you can get a rough
guestimate by comparing your ride to a Falcon, Eagle, U2... etc. Also move
it via Pagen's instructions up or down, left or right slightly for draggy
harnesses and so on... should get you pretty close. Print it out and get
out a ruler... Or... this might work
http://buteo.szm.sk/work/polar_sim.htm Other than that you could just
fly about 26-29 or so and be darn close in no wind with lots of gliders.
Not sure how good our airspeed indicators are anyway. Or lastly I have a
convolued spread sheet that my be of some help.
