I came across
this thread and I knew that only the green LED was lit on my FrSky R-XSR receiver when it is bound to my radio. So I realised I had accidentally put the receiver in CPPM mode during the binding process
. FPort obviously needs SBUS mode so I've now put the receiver in SBUS mode (green and blue LED on when bound) and the jitter on my tail servo is gone, hourray
!!!
Now I noticed that, from time to time, my radio loses telemetry as described
here, so I might downgrade the F.port firmware on the receiver from 2.1.1 to 2.1.0 and see whether that solves that issue.
As indicated in my first post, the tail servo makes occasionally a crackling noise (a bit similar to a Geiger counter with low radiation levels).
Is this normal or does it mean the servo is EOL ?
