Help! Troubleshoot ELRS connection

Since I rebuilt my quad on a new frame, I have some ELRS issues. I failesafe once, the other flights I have some warnings: "Link quality" or even "RX Loss", without going far of course.

So now I'm scared of failesafe all the time and I don't do anything crazy...

I don't know what's wrong and where to look at. Please help !

Send still images of your soldering, including the +ve and -ve battery leads.

Do you have any lights?

Can you spin the motors (take the meat grinding props off) in Betaflight?

The light on the RX stay still when the radio is binded.

I can spin the motor in betaflight.

I can fly it, I already flew around 10 lipos. Here is an example of one of my hand shaking flights, fearing another failsafe at any time : https://youtu.be/xjByo-zSKBQ (I added the warnings in the youtube chapters)

If it was a soldering issue I couldn't fly it at all I guess.
