Hello. I have an issue with my speedy bee f7 v2. The receiver connects perfectly when plugged into betaflight, I can see stick movements, modes, arming, etc. But when I disconnect the usb, and plug in the battery, none of the stick commands work, arming, or anything.
Strangely the receiver is still powered and connected to the transmitter (tbs tango 2).
Any idea what this could be?

Is this an analog build or digital? Do you see the Betaflight OSD? Any leds on the FC when you plug-in a lipo?
