Worst day ever..
Yesterday the rotorpixel gimbal wasnt good.. and today i had a flyaway!

:evil:
I did everything the same as all of my flights.. must have been 60 flights or something. Didnt do anything strange. And i had 8 satellites. leds were green and i was like 30 meters up and suddenly i saw 4 red flashing leds and i couldnt stop my PV anymore! Now it's gone! Find my vision doesnt work really good.. bye bye Phantom. Havnt got money for a new 1. So that's it
****!
I received my P2V+ a couple of weeks but have not flown it yet as I have had little time and bad (Swiss) weather etc...
Nevertheless I tried to turn on the bird for a "dry run" (between two showers) and found out it could not get enough satellites locked (4 or 5 max) to get green light on.
So I searched the net a little and found this :
http://satpredictor.navcomtech.com/ :!:
And indeed, at the exact time of my "dry run" there where very little sats overhead (6 sats max according to
http://satpredictor.navcomtech.com/) I did a second "dry run" at a time when the site predicted about 8 or more sats over my head and got green lights in no time.
Could this have played a role in your flyaway : Many sats at take off time, then suddenly several sats disappear and boum, the bird is gone...?
It would be interesting to check the sat coverage (at the sat prediction site) for the day and time you had your flyaway... If your flyaway coincides with low sat coverage we may have a lead in what causes them : a sudden drop in sat coverage :?:
Will add that where I live there are no close mountains but my house has its back against a hill (in a kind of very small and narrow valley) that may make it more difficult to get good sat lock. I'll be cautious and wait for a very good coverage prediction before my first flight.
Oh, and for those of you who have IOS devices (iPads or iPhones) : I learned that there is no IOS app that can show how many sats your IOS device is hooked to (no api, devs cant build this in and show the info in their apps) but there is a free app (GPS Status) that will show the precision of the GPS coverage at current time :

Also note that (for my area) the bad coverage period moves to an earlier time every day, about 10 minutes earlier every day. Go to the prediction site, enter your address/position, time etc and then click NEXT day several times and you'll see the red or yellow bars (6 sats max) move to the left...
Hope this helps but I'm very sorry for your lost bird...
