A Fire Rescue DJI Mavic 2 Enterprise was purchased used in great condition from a pervious owner. During test flight near the firehouse, it came crashing down in the parking lot. What would cause this? Everything was calibrated and working perfect. 15 minutes into the flight with 40% or so battery remaining. What can I do now if care was expired from previous owner? Thanks for any help and info.
