So I've learned I can add RSSI to my betaflight OSD display. On my mobula6 it says 10, and goes down to maybe 9 or 8 if I go in other rooms. Is 10 = 100% ? I was expecting 100 or 99 to be the max. Betaflight is set to warn under 20. I have a DX9, could I be having radio issues and just don't know it? I did just sink a quad because signal lost when it was nearby. How can I check if I'm having Tx issues?
