While hovering to land my phantom 4 pro, it suddenly began to spiral clockwise out of control and crash. I am Working with DJI to Repair or Replace under 12-month Warranty. I have been flying Drones for quite some time and am confident in my ability to do so, however this event has shaken me. There are so many things that run thru your mind as you watch your investment spiral uncontrollably out of the sky. Things could have been much worse if this event would have occurred further from me or landed on someone or their property. I felt very confident using DJI products but now feel very cautious in my approach to using this Product. Just like you, I have put my money and trust in this great revolutionary technology from DJI. Order of events: While Flying I Received Low Battery Warning, Returning GO Home initiated, I Canceled RTH and Manually Returned (sport Mode), High Wind Velocity warning, (not uncommon) it was not a windy day Received Warning: Weak GPS Signal, Received Warning: Ultrasonic System Error: Land as soon as possible, Received Warning: Motor Obstructed, Received Warning: Gimble Roll Reached Movement Limit, The Controls Auto Changed to Atti Mode, Received Warning: Compass Error: Exit P-GPS Mode: Received Warning: Weak GPS Signal. Positional accuracy may be compromised. Phantom 4 Pro goes into a Sudden uncontrollable clockwise spiral inverting several times and Registered horizontal speed of 108.2 mph, 128 Ft. off the ground. Spinning and crashing, all control over the Phantom 4 Pro was lost, The Phantom 4 pro crashed down into cedar trees in a vacant lot next to us, sustaining damage to housing, props, Camera, gimbal, ex. I was in complete Shock that this could ever happen. There were no obstacles or collisions, no bird strikes, weather was clear blue skies, no wind ex. Just sudden uncontrollable clockwise spinning. All of the Errors and crash happened within seconds of each other and the video and control inputs show hover, descending and then sudden loss of control. I contacted DJI 1 (818) 235-0789 and let them know what happened. The Representative directed me to DJI Support Webpage and generating a RMA for return/repair/replacement... My only concern is DJI's policy, that if you do not agree to DJI repair, then you are charged $65 an Hour for the Diagnostic Analysis which you must agree to in order to receive a RMA. Should I be concerned, I have flight log and Recorded video showing the crash? I also have insurance on the Phantom 4 and could just file a claim, but don’t want to do that if what happened falls under warranty and it can be fixed or replaced. Video of Phantom 4 Malfunction:
