    Auto Takeoffs/Landings

    Nobody has answered part of the original question: pros & cons of each... I have always assumed that auto-take off and auto-landing are preferred in certain situations, such as with wind. The reason behind -I don't know if I'm right- is that the internal computer of the drone is capable of...

    Looking for TECHNICAL info on SENSORS & CAMERA

    Greeting everybody, I have been commissioned by a Spanish publisher, specialized in photography books (www.fotoruta.com), to write a book on Aerial Photography with Drones. I am now writing the chapter on hardware: drones and it's components. I have researched Internet -including this forum-...

    Intermittent Atti-Opti-GPS modes...

    Hi, just to update this thread: I contacted DJI technical support. As soon as I explained the issue, they told me they have to send the P4A (without the RC) to Amsterdam (Europe's central TS) to have it checked and -probably- get it replaced. And that is exactly what happened: 2 weeks later I...

    Where is the flight data stored? (a) P4P (b) micro SD (c) RC or (e) Tablet?

    Thanks everybody for the useful information. Just one more point: If I fly several drones and with several tablets/phones, is there a way to have all flight info in one place? (e.g. if I fly a friend's drone with my iPad or if I fly my P4A with someone's tablet, in both cases I will be missing...

    Where is the flight data stored? (a) P4P (b) micro SD (c) RC or (e) Tablet?

    Hi, I am a bit confused as to where the flight data is stored (and what kind of information is contained in each type of file). 1- If I connect my P4A to DJI Assistant 2 (on my laptop) I can download .DAT files (stored inside the P4A or in the micro SD card?). What type of information do these...

    Intermittent Atti-Opti-GPS modes...

    FYI, I flew the P4A this afternoon and on starting it up, I got this message in DJI GO 4 app: "GPS encounters disconnect please reset and check connection" (it is not the first time it happens). I swithched it off -only the P4A- and then on again. Everything worked fine during a 12 minute...

    Intermittent Atti-Opti-GPS modes...

    Hi I enclose a few other DAT files. I am not sure exactly which ones correspond to the intermittent problem. In any case, some of these files correspond to flight attempts, since I didn't take off due to the absense of GPS position (which I believe is the original problem). I hope this helps...

    Thanks for your reply. Here are the links to two DAT Files: 1- http://www.mmerino.com/varios/FLY032.DAT (flight with intermittent ATTI-GPS issues) 2- http://www.mmerino.com/varios/FLY033.DAT (flight with normal GPS mode) TIA

    Intermittent Atti-Opti-GPS modes...

    Hi, I have a P4A since a month or so. Since the 3rd or 4th flight I keep getting intermittent mode changes. This is what happens (in open groung in the countryside) : power on sequence (RC -> P4A -> Ipad 4 mini). I get green light (GPS mode with 14-18 sats) and Home position recorded. I take off...
