Yesterday as I was taxing out to fly my I/4 scale Edge 540 I noticed my elevator not working so I hit the throttle cut on my 9C and went out to retreive it.....took it apart rehooked everything and still the same thing....the dual elevator servos were drooping down and they were moving a little. When I got home, I changed out the Y harness and the elevator would work for a little while and then droop I tried a new crystal and thought I had it whipped but I turned on a little later and the elevator began the same routine.

I've been flying acitively for 20 years and have never come up on anything as strange as this...when this is happening I have control on all the other functions and I don't believe the 2 ele. servo's would go out at the same time. Suggestions???????
