during stabilize flight, the controls went to zero , and the motor output went to 1500 .
looks like a bug to me !
logs attached
If you add RCIN Channel 3, it looks like you dropped the throttle to 0.
Also, motors 2 and 4 are working harder than 1 and 3 so you’re centre of gravity is too far forward.
It’s always fun to look at logs where user diagnosed a “bug” in record time, just to discover the build quality and setup is equally hastened.
