    Anyone know above what wind speeds we should be keeping our phantoms grounded. Preferably in KM/H.
    I've 25kph winds here today and my phontom dances around in the air a fair bit and can drift up and down by anything up to about 10ft. Just wondering if this is normal.

    Sorry having a lazy day. I'm seeing somewhere 17.8mph which is close on 28kph which would increase by 1.5x at 400 odd feet. I'm at 25kph here today so a bit close for comfort I'd say.

    After flying for a while I figured that anything over 6 meters/second was about the limit for smooth flying and over that the batteries start to run down faster too,so I made that my limit and I don't bother going out if the forecast is 6m/s or higher.

    Speed conversion.
    10.3 Meters Per second
    20.0 Knots
    37.1 Kilometers Per Hour
    23.0 Miles Per Hour

    I used that set of numbers because DJI stated the top speed of the original Phantom was 10 meters per second.
    I presume that was on a calm day in GPS mode as in ATTI mode on a breezy day travelling with the wind I've seen my Phantom disappear into the distance very quickly,way over 40 kph.

    Thanks for the link barefootbeachcombing,that's a great chart on the wiki page.

    DJI are very conservative in their recommendations in the manual - as they have to be in a document for users of all levels of (in)experience.
    The Phantom will handle more wind than most users imagine.
    It can hold its own in above 20 knots.
    Just make sure you fly upwind first to check how it handles things.

    Depending on the area your flying in I fly no matter what the wind as long as I have the room to compensate. Those are the days I try to bream my speed records.

    You can fly in any wind conditions that you like, but if you want your Phantom back, then don't fly in anything over 20 MPH. If the wind is at all gusty then vertical drift is quite normal because the wind gusts change the barometric pressure inside the shell which the Phantom interprets as an altitude change, so it climbs or drops to compensate.

    Also, if your sat count drops to less than 6 (which it can do in Ireland quite a bit!) it will switch to ATTI mode and could disappear quite quickly! There will be other days to fly. Unless you're doing an event, I'd wait.

    LOL me too. My Border Collie disappears when any of the drones get taken out. Although at the park she'll tolerate the Phantom because it's not low for very long.

    Your very correct on this one. It can get pretty hairy trying to land these in high wind and in atti mode. Been there before. Just make sure your confident in flying in attitude.
