[QUOTE="Spark 317, post: 118692, member: 894"] I'm not an expert at reading the logs, but it looks like you didn't wait for the Spark to establish a Home Point (satellite count too low) and just launched in Atti-mode. I don't know what's going on with the VPS other than it appears to be not working or getting conflicting information from the other components (GPS, barometer, etc). One of data messages also indicated a GEO zone of some type like near an airport and initiating an Auto land. I had a very erratic flight once that lasted 30 seconds due to me placing a strobe light on the bottom next to the VPS camera. It never went over 20 feet in height but bounced up and down about a foot or two in the air. I moved the strobe away from the camera and never had a problem since. I think the intense flashing of the strobe affected the Sparks ability to "see" the ground and the poor thing didn't know what to do. The Spark should be able to fly without GPS, such as indoors, and would require the VPS to be operating properly in a well lit environment so it can "see" the surface underneath. Just a guess. ?
