Im having trouble with getting the my quadcopter in loiter to keep its position. It seems like its loosing the signal, but my gcs says the GpsHDOP is at .8 and there are at least 10 sats. it will hold for a few minutes then suddenly takes off in a direction without changing altitude. I can recover it by switching back to stabilize. Its as if it received a command to go to a waypoint.
I have set up a few of these and haven't had any trouble, but this one is a little sketchy. Does anyone have any ideas on how to troubleshoot this and get the system working more consistently.
