Hi guys... i'm a newbie phantompilot and i'm searching the internet for all the info that i can get. Through my searches, i found an info that i whish to share with all of you: http://origin-www.swpc.noaa.gov/impacts ... ps-systems Be aware of the geomagnetic storm that can shuffle your's phantoms gps module!!! Expecially if you are flying a Phantom 2 Vision Plus in Phantom mode wich doesn't allow you to disengage the GPS module at all.... I think this was the cause of many flyaways that i have read about... NOTE: On the homepage of the site that i have linked are also realtime info and forecast of the geomagnetic storms classified in a human-friendly way... Hope that will help! Bye!
