Thank you for your patient. I appreciate it.
I don’t have power supply problem. The switch of VTX power can turn on the LED which I did want to do so and it happened anyway. and I don’t know why and I would to know why.
It is a coincident which I would find it out why.
yes I want to separate the led function from the VTX. WS2812 connected to the LED of matekF765wing (http://www.mateksys.com/?portfolio=f765-wing#tab-id-5) . VTX is rushtank plus by using smartaudio to adjust the power which was working fine.
Yes. the switch is the RC channel assignment.
pleae tell me if there is still anything missing. I am chinese and telling such stuff is kind chanllenge to me. but I will try to make it clear.
Thank you for your time.
another two things to tell if you could help.
1, why the failsafe is on for the reason3. the rssi was pretty much 50% above. and the plane was just couple of km away. can you tell what is the reason to cause this failsafe.

2, why powering on the FC while the VTX power switch is at non low position. then I switch it again. the FC will be rebooted even the plane was armed. lucky I didn’t change it when the plane in the air.
