I'm new to the forum and this is my 1st post... sorry, it's a long one.

I've been having ALOT of go4 crashes lately so I used the k1 game recorder to record some test flights so I could review the flights & have a good reference to compare to the dji flight logs

I flew 3 batteries the other day.  7 take offs & landings: 3 vlos with crashed go4,  3 low battery(1 go4 crash when landed and motors turned off) & 1 good 4min flight.  I also managed to restart go4 once in mid air after it disappeared, leaving me on the k1 home screen.   That's 5 go4 crashes in < 1hr flight time.  However, I never lost control of the p4p no matter what the display said or did so I was always able to bring it back vlos. Go4 only offered to return home once but since I was already flying home vlos with full control, I didn't see it until I reviewed the screen captures.

I was flying over a sports complex.  It has 5 soccer fields & 6 little league diamonds. It's closed for the winter and I have permission.  The 2.4 g band shows very little interference ( only 2 short red lines when I checked) and I have over 1000' x 1000' unobstructed vlos flying area at  H >70’

Next: detailed flights...
