Hi Harry.

No, I have not contacted Weatronic directly yet. I was hoping that someone might have an answer online.
I also asked on the german forum, and someone suggested that I might set a failsafe position for the servo. Right now my failsafe is set to "Hold" as is default setting, but until there is a signal transmitted from the RX it seems that this does not work.

The gear will be driven by a JetTronics valve, and that may not be quite as affected as a normal analogue servo.
