Fortunately I was able to level the aircraft before impact and therefore there was very little damage to the components, see the attached photo. All of the control linkages were inspected at the crash site, everything was still connected. I checked all of the control surface servos when I got home, they all seemed to be working properly, however I need to mark the two aileron servos as possible suspects.
I had 26 flights on this aircraft when the crash occurred, I agree that it does seem unlikely to be turbine noise on the 26th flight. If I were to send you the Mercury is there some kind of diagnostic test you can run on it to make sure there is nothing else wrong with it?
Thanks again for the help,
