I bought the ft gremlin about a week and a half ago. The issue is that in betaflight, it does not show any receiver input on the receiver tab. All of the bars are at 0. I have a spektrum dx8e with a spm4648 remote receiver. The receiver shows a solid orange light indicating that it is bound. I have tried switching back and forth between Spektrum 2048 and 1024. It is still reading 0. Does anyone know the solution to this problem?
