I have the PowerBox Mercury and have about 25 flights on it. I have GPS and battery voltage sent back to an Futaba 18MZ and everything was working fine. Today there are no readouts for the GPS or battery voltage, antenna fades...... I am showing the battery voltage internal of the receiver of 7.5 volts telling me that some of the telemetry is working. The receivers are 7008.
Any suggestions of what to look for? I went through the set up and verified it is still set for S Bus
