You will need to provide the flight log from each one, with a description of the incident and details of how it is setup , the calibrations done, trimming, tuning, and any other relevant details.

The more information you give us the easier it is to determine what might have happened.

Didn’t you ground check your controls before flight?
What do you mean “impossible to Fly”?
