3) video displays well on tablet until you go into a flight mode (selfe etc) then is distorts the crap out of the video on the tablet. not sure why this is - didn't do it before.
4) AND OF COURSE THAT SHITTY GPS that looses lock at the drop of a hat. Seriously, a bird flew past and it lost lock for about 5 seconds. It seams to me that a solution would be to place the antenna on top of the metal housing under the plastic cover. Also using an ACTIVE 32mm patch antenna with LNA Gain and a SAW filter (and possibly using the metal bracket as a solid ground plane to reduce multipath) AND moving to the uBlox M8N would provide a better solution. I speak from nearly 30 years of GPS/GNSS integration into consumer/survey grade systems. I have at least 50 GPS at hand and the only time I have seen a GPS behave like this is when either the antenna is faulty or the coax cable from the antenna to the board is faulty. 3DR needs to stop talking around this with nonsense PDOP/HPDOP blah blah blah and provide a physical modification to the current assembly - its just bad engineering. all this claptrap about the M8N being to sensitive is primarily due to crapy antenna. All my millimeter accurate Survey Grade GNSS use multi constellation and I have no problems - why, cause they have decent, well designed, antennas. Come On 3DR!
