Hi
I have a DJI450 clone flying the HK pilot mega2.7. My first flight a few weeks ago. Was all going well until it got a bit out of control and I tried to land. I dumped the throttle hoping for a minor crash and then the machines took over and it decided to go for a wee flight by itself.
I could hear it changing flight modes continuously so I’m guessing the fail-safes were trying to kick in. Had a ringfence set at 30m and loss of signal ones etc.
Thankfully I had telemetry connection and I managed to track it to a neighbours place about 300m down the road.
I have looked at the KML and it looks like it had a nice little tour of my neighbourhood before coming to “land” in a garden.
I have attached the logs, any help as to why it flew off would be appreciated?
I’m scared to fly again until I work it out.

Looks like you had a GPS issue as min sats are 0, HDOP is 99.99 and there were two GPS glitches.

I have similar problem my f45 went from Stabilize fashion suddenly like a rocket. here at my anelyse the bin file. I think my problem was set viritueel fencing. Greetings Van Den Berg

if this is a different problem and somebody knows what this causes you want to know this. by turning off the radio device still a real problem in the GPS system back on RTL landed so is still very strange
