We can't support any polar curves for special gliders and you will certainly understand that we can and will not publish the polar values of gliders available.
1st Reason: To avoid problems with the manufacturers
2nd Reason: The polar depends also on pilots weight, type of harness, flying experience, etc.
To get best help from your IQ-Competition you should determine your own polar yourself:
a) Adjust your flywheel sensor (setmode 19) with help of a GPS receiver. Fly on a calm day with a speed of about 50 km/h (30 MPH) and compare the readings of airspeed and groundspeed. Repeat same test while heading in various other compass directions.
b) Determine the airspeed and value of minimum sink for your glider. The result should be about 40 km/h (24 MPH) and 1 m/s (200 FPM)
c) Determine the second polar point at a higher speed (appx. 75 km/h [46 MPH]) but not the max speed of your glider; the sink rate here should be about 3m/s (600 FPM) or better.
Before using Nominal-speed or McCready functions as well the final glide calculations, try to understand the theory behind their use. Read our manual carefully, study literature relative to the matter or talk with experienced pilots.
For myself I fly with a TEC of 70%, an analog vario time constant of 1.6 sec, and instead of the digital vario in setmode 9 I like to see the digital L/D ratio.
