Flew my vision for the first time this evening. Had a tough time getting the wifi to connect in front of the house and when it did it would freeze as others mentioned. Phantom flew well and is super stable. I have GOM player and am afraid to have windows media take over my system and interfere with GOM. What are you folks using to view the MP4 video files? I am trying to upload to youtube and even they are telling me they don't recognize the file type but will try. I have put the microcard into a different brand holder. Could that be a problem? The file shows as an MP4 on my computer. Thanks.
