    Everybody carries a cell phone.
    Cell phones causing a fly-away doesn't make any sense at all. Interfering with 5.8 ghz is irrelevant - it is not used for flight controls, interfering with 2.4 ghz would cause the drone to fail-safe. You can't accidentally control your drone with a rouge 2.4ghz signal, it's digital not analog. You can't interfere with GPS from your phone.

    Do a search on google with these keywords "2.4 ghz interference gps".
    Do a test with your cell Phone next to the yuneec and watch the satellite reception dropping. It make no sense if you look at the signals but rf leaks are all over the place.

    All cell phones are digital, no more Analog.

    Cell phones have 2.4 and gps running at the same time all the time.

    But a cell phone can't fly away. :)

    According to Marco, if you tape one to a drone it will.

    Most cell phones don't have real GPS receivers. They use AGPS which relies on cell phone tower triangulation instead of the satellites.

    A-gps is part of how the GPS in phones work.
    Assisted GPS (abbreviated generally as A-GPS and less commonly as aGPS) is a system that is often able to significantly improve the startup performance, ortime-to-first-fix (TTFF)

    From the rest of the Wiki- To be more precise, "A-GPS" features are mostly dependent on an internet network and/or connection to an ISP (or CNP, in the case of CP/mobile-phone device linked to a Cellular Network Provider data service). A mobile (CellPhone/SmartPhone) device featured with "A-GPS" (no additional "S-GPS"/Standalone-GPS feature to be selected as alternative, or there is no "Hybrid GPS" as a complete A-GPS/S-GPS hybrid features in one device) can work only when there is an internet link/connection to an ISP/CNP - it is useless in areas with no coverage of internet link (or no BTS towers nearby, in the case on CNP service coverage area) to connect to those A-GPS servers (that are usually provided by CNPs). On the other hand, an "S-GPS" (including "Dedicated GPS") device/feature requires no connection to internet/network to obtain GPS data since it connects directly to GPS satellites overhead.


    I'm not sure about Android hardware but iPhones and iPads do not have S-gps and don't work without a data connection. That's why they can't be used as navigation devices in planes or boats in remote areas without an external GPS receiver. I used to work for iOS support and this issue came up some times.

    I am disabled and can't walk. Can set up my new q500 from my power chair or would it be best doing it from a wheel chair that does not have battery in it? By the way this is a fantastic forum. Thanks.

    Hi Kip, Welcome.

    In an ideal world it would be best to do the compass calibration away from any metal. I even keep my iphone away from mine as it does affect the compass. You will only have to do this once so if you can get some help I think you would benefit big time. Mind you make sure you watch the video as trying to explain to someone how to turn the bird is fun :)

    Other than that I would do everything on an adjacent table and you should be good to go.

    Enjoy your flying and if you need any help be sure to ask here, however trivial. That is what the forum is for.

    Even the metal of the wheelchair could affect the compass calibration.

    Best to do as MrBurns suggested, and have someone do the manipulation for you.

    That is what we did. Works fine and can't wait for the rains in Oregon to stop so I can continue flying again.
