Motor almost off in the air and high cliping

hi!

Ok, some news. I have change the FC and the FC carrier, so no more motor problem.

But the cliping still there.

Here is the link to the log

I have realize the cliping happend at the moment of hard braking. For example, rolling the drone left to right very hard, when I do a hard braking especially to de left, 100 or more cliping appear.

If the drone is hovering, no cliping. if the drone is moving slow, no cliping. But running faster and turn right or left faster, cliping appear.

Its normal?

I have tried with another kind of props, and the result is the same.
