Id like to generate the drag polar for my glider. I talked to my
project advisor briefly and he had me check out http://www.eagletreesystems.com/
which makes data recorders for RC aircraft. The cool thing is that I
could get airspeed and altitude readouts for the entire flight, and
then find the polar from that.


The data is easily available from almost any modern vario and GPS.
It would be wonderful if it were that simple. Unfortunately the air you
are flying through moves too.
