The idea of the string, or the string on each side, is not that that it is a
true angle; but, if the canopy sides are at a promising height and also an
adiquate distance from the wing, that the positions can be marked as
calibration points for the particular angles of interest--such as best L/D
and minimum sink.


I understand the process. I currently have a yaw string on my glider. The other canopy strings might be somewhat effective; however, I'm spoiled. I flew 13 years in the US Navy with "real" AOA systems. I am not looking for a crude substitute. I'm looking for the real thing.
