[QUOTE="SPark_South_Oz, post: 124812, member: 17032"] It might have been in atti mode, the device screen would have shown this of course, or position mode more usual in this case until sats locked on and GPS mode kicks in. But the way it flew off uncontrollable sounds like you might have had an IMU / compass conflict. This happens A LOT to pilots on the MavicPilots forum, quite well known issue. Haven't seen it reported here much, either the Spark is less susceptible, or there are fewer users of the older Sparks don't see it as much. What happens is minor magnetic interference (metal bonnet, rebar in sidewalk, etc) CAN sometimes make the 2 aircraft compass records different to each other on take off. There is NO magnetic interference warning in these cases. The aircraft takes off, and on moving a stick, the conflict appears, the aircraft FC tries adjusting to correct the 'error' of direction, the aircraft usually takes off at 90 degrees to sometimes 180 degrees and is totally uncontrollable. Moving the sticks can help slow it a little, but it ramps up and generally flys off at normal P mode speed (if set in that). If the aircraft doesn't crash or flyaway sooner, the 2 eventually reconcile and control is regained, but usually it takes too long and the aircraft is often damaged or lost. Just watch the map icon on take off. If the red arrow on the map matches direction the aircraft is facing on the ground, all is good. If it's off, then there is slight interference and best to turn off the drone / comtroller, move the drone a little bit away, and try start up again. [/QUOTE]
