This winter’s projects include adding an artificial horizon (AH) and
PowerFlarm to my panel. I am trying to determine which AH would be
best suited for occasional use in XC soaring flights. It would be
very helpful to hear from pilots with experience using AH in gliders.
Attributes I think would be important include short power up time and
ability to deal with unusual attitudes. So far, I have read about
these products:

Dynon Avionics EFIS-D6 (http://www.dynonavionics.com/docs/
D6_intro.html)
PCFlightsystems eGyro-2 (http://www.pcflightsystems.com/)
MGL Avionics AV-1 (http://www.mglavionics.co.za/).

Comments on these and any others would be greatly appreciated. Thanks
