Fly aways caused by weird Y-Axis vibrations

Hello Community,

I would like to get some hints from you about what can be the root cause of the consecutives fly away I have in my flights, when I try do some aggressive with pitch forward in position hold or altitude hold modes.

For me, the problem is something related to frame rigidity, or you have some screws in the motor mounts that are not tight. You can try the motor test in Mission Planner and check one by one if something is not ok.
