I have it on my L39 due to the close proximity of the elevator servo but it does not cause any problems with engine running.
Yep, same. A few of my servos appear to cause rpm fluctuation when the engine's not running but when it is, the fluctuations aren't registered. Hope you get your problem sorted out. As we all know, the guys and gals at wren will do all they can to help you.
