Standard - FLY AWAY ISSUES???
"Good morning Rod :
I have several question hope you will help ?
I am flying with I Pad air and phantom 3 standard.
I've been at this about a month.
I flew straight up 110 feet (first time over 45 feet scared the hell out of me,) came down to 20 feet and went into 18 foot poi mode ,phantom circled and screen went blank no control . disconnected , land immediately, land immediately controls have timed out,repeated several times
New charge on battery so I had maybe 15 minutes to figure out what to do. switch RC off and on ,no change. went into setting initiated Phantom YFIY and back in business with last light on battery flashing. Now i'm afraid to fly ,what if It had been going straight up like 20 seconds earlier, I would not know anything but its gone by-by. I was under the impression if something like this happened it would RTH."
I would delete your email, and phone#, anybody in the world, can see that.
Also this forum works best by sharing information instead of one on one.
Land immediately? Where did this come from?
Were you using DJI-GO?
I'm not familiar with POI on DJI-GO.
RTH has many variables and options, you have a lot to learn about RTH, you need to test it and understand. Its like getting a GPS, never using it until your lost.
How long did you have remote turned off?
Quickest way to look at what happen is to upload your flight that is on your ipad to
https://www.phantomhelp.com/LogViewer/Upload/
Will will need to use iTunes on a pc, and a pc to uploaded it once you can view it, you copy and past that URL to this thread.
