It’s overweight/underpowered.
There is output oscillation
The Notch Filter has not been configured.

Should probably be on 6S power at that weight or lighter weight on 4S.

Okay, at the end of the flight I had a huge drop in tension. So I deduced that the setup for 4S could be bad. With your analysis, I will replace it with 6S and test again.

I didn’t see about the Notch Filter. I will study and configure.

Thanks!

What is output oscillation?

This:

If you are switching to 6S power many parameters will change so don’t worry about it now.
