US Just started using paparazzi on a Twinstar. It works reasonably well, but I'm still learning to tune it (altitude does not work well).

Media:Flight_09_12_10__07_03_14.kmz This file can be opened with googleearth. (googleearth/KML works well in ubuntu, see [1] if using nvidia you'll need their drivers) If you download Flight_09_12_10__07_03_14.kmz and 'unzip' it you can see the files used to make it as well. An example of using the converter from the unzipped Flight_09_12_10__07_03_14.kmz:

  'perl 09_12_10__07_03_14/utm_geo_convertion.pl 09_12_10__07_03_14.data -scale_plane=15.0'

The thing that I don't currently understand how to do in KML is the conversion from the airplane's frame of reference to the world frame of reference. I need that to be able to show the rudder, ailerons and elevator in there actual positions. I haven't figured out the math yet, the likely candidates are DH transform, Euler angles, or Quaternions....I seem to have forgotten my linear algebra.
