Severity: Medium Risk

   Triggered when the aircraft pitches (tips forward/backward) or rolls (tips right/left) beyond normal operating parameters.

Possible causes include 1) a propeller breaking or falling off 2) an exceptionally strong wind gust or 3) a collision or a bird strike.

It is strongly advised that you thoroughly inspect the aircraft for damage if you receive this warning. An inspection should include checking the propellers for cracks or damage, looking for cracks in the outer shell, specifically around the motors which are areas more prone to cracks, and testing the gimbal operation. We also recommend reviewing any other notifications for this flight to better understand the cause of this warning.

After performing a visual inspection, we encourage you to conduct a short test flight, keeping the aircraft close to the ground. Does the drone hover evenly (not titled)? Listen for any abnormal noises and keep an eye on the flight app for any unusual tips/warnings.
