I am evaluating ifly GPS and so far am impressed except for one issue.  Am using Stratux with the AHRS board.  When I roll into a turn the AI correctly shows the bank angle but if I hold the turn the AI returns to level in a few seconds.  On the ground it holds the bank angle as it should.  I have the latest Sratux software.  Have gone through calibration a few times.  Any ideas?  Searched but did not find anything related.  
Thanks DHS
