I found another article about quadcopters, and here it is.
I’ve been flying fpv and building drones for over 5 years now and I’m a little embarrassed to post this question. if I unplug the air unit from the transtec beetle, it will arm and fly just fine. but when I plug the air unit into the beetle and turn on my goggles it just keeps beeping away and won’t arm. connecting to betaflight doesn’t show me any warnings either. I have betaflight OSD on and I was hoping it would show the arming/warning status in the goggles but it doesn’t. everything is calibrated and good to go. I must be missing something very simple. In my defense this is the first time using the DJI HD fpv system.
