I've decided to try using oplink as ppm module from transmitter to my revo board as alternative to using 2.4ghz. For this I modified a broken flysky fs-t6 to use oplink module instead. So far very happy (is oplink a stable enough solution in the long run?)
I'm also using minoposd and would like to show rssi from the oplink receiver on the revo. I checked in the gcs and it seems that ReceiverStatus rssi always shows 100%. This is even so when I turn off the transmitter. What I want is the signal strength indication from the oplink tab to be shown as the rssi value on the osd. Is this configurable somehow?
