Stumbled upon it at the Alabeo website: http://www.alabeo.com/index.php?accion=update

 

"Modifications:
-        Added rudder and ailerons trim center indicators.
-        Fixed COMM1 STBY/knob issue.
-        Transponder ON/OFF button fixed.

You don t need this update if you downloaded the aircraft after January 30^th, 2013, 2030MT"

Thanks for the heads up. Got to admit, I wasn't too interested in this model when it was first announced but the idea grew on me over time. I wound up buying it right after release and I've been having quite a good time with it.
