I tried one a year ago but eventually had to pull it out because it
wouldn't stay calibrated. The lightness of the glider seemed to make
it too sensitive to bumps, and when I pulled out of thermals it would
be off kilter. Sometimes it would do the same flying straight and
level.

The dealer worked with me to try all the various software settings for
sensitivty and calibration to make it work but couldn't.
