Would lime dome advice from fellow flyers about my fist flight problem. Well did all my pre flight checks and calibrations before take off. Took off and 45s into flight list gps signal drone shot off, git signal back so hit return to home quickly.On reviewing flight log found that 45s into flight I had yaw error, then 50s lost GPS. Has anyone had this and if so how did yoh over come it.

A few more details are needed to help you with that, e.g. about the area you were flying in and possible sources of interference. If you like you may also upload your flightrecord to this site http://www.phantomhelp.com/LogViewer/Upload/ and share the link with us.

Please try to fly the drone in another open area and avoid the possibilities of the interference, ensure that the drone has updated to the latest firmware. Please keep us updated if the issue persists, or you can also contact our support for a further help. http://www.dji.com/support
