I tried the transmitter on multiple channels, including the ail / elev channels where I have 100%+ travel setup and still no green light... I have another transmitter on another airplane that I will remove and try on this airplane... I will let you know if the other transmitter provides the same results...

Also, I believe the green transmitter LED always lights up when the Rx was powered up... Then when the circuit becomes active, the red receiver LED lights up... In my case, I am not getting either a green or red LED when the system is powered up...

Thanks
