I just built my first drone and 5 seconds after I took off it completely shut down then rebooted with only the vtx working. So far I've figured out that my receiver is broken. But my flight controller is in a very situational issue. It does not power up when plugged into my lipo battery, but the vtx still works and transmits a signal (just a black screen). But when I plug my fc into my computer it powers up and the LEDs go on and it operates in betaflight as normal. I've that it is usually that a fc will not work under battery or USB power, but for me it still gets power properly just only to the vtx. When the USB and battery are in the camera works fine but the moment I unplug the USB cable the camera no longer works and the LEDs on the fc go out, but the vtx is stable. I'm hoping someone on here is able to help me find the cause of this and what I can do to resolve this issue.
