So I bought a Inspire, I drove home all excited and ready to fly. I charged the batteries and read the manual. I spent five min flying it the night I bought it just to test it. Flew it low and slow..... No problems was a dream! Woke up early the next morning and went to a open field and did my pre flight checklist. I calibrated the compass and checked the gimble. I took off and flew over the water and checked the gimble again. Still everything is working like a dream. So with everything looking good I take off and see what she can do at about 30 feet. I bring it back and start to play with the camera. Still working great! Here is where things start to get bad.... I started to climb and I noticed it was going up to fast so I let off the stick but its still going up. Next thing I know it stops at max altitude 400FT. I let off the controls to let it stabilize, after a few seconds it starts to rock back and forth. It becomes very very unstable so I pull all the way down to bring it down ASAP to check on it. It doesnt respond instead it starts flying in small circles that get larger and larger. I realize something is not right so I hit RTH. Then things get really bad. The inspire doesnt turn to come home. I press record so that I have the issue on camera. It doesnt respond at all instead it takes off flying sideways and spinning out of control. Pretty soon the whole unit is flying full speed in a massive circle. I cancel RTH and try to manually control it and get it on the ground. No luck it wont respond. Now its headed toward a park so I try to kill the unit but still nothing. At this point its spinning in circles as it flys in circles. At this point I am in O Sh** mode. I try everything with no luck. I watch in horror as the unit is headed full speed towards a tree about a mile away. I heard the crash as I look down and my screen freezes and says signal lost. I find the unit laying in pieces on the ground in a old mans back yard. The impact was so hard that it tore the battery out and disconnected the gimble (both of which I never found). I checked the flight app and no video was cached. I went back to the flight log and watched it. It shows the mayhem but I noticed that it showed at least one time that landing was complete even though it was still flying. It shows the command for RTH on the screen. Has anyone ever seen this? Does anyone know what this is? The dealer wants to give me another unit because obviously this is a faulty unit. He says he has seen this happen once before and whats creepy he said it was almost the same exact pattern. He however didnt know what caused it. Even though the dealer wants to replace the unit DJI is giving the dealer a hard time and wanting all the flight data pulled off the unit. So Im currently without a unit Im hoping someone can shed light on what happened. Ill upload a picture of the flight log when I get my phone.
