    Sometimes after a flight, i land and put the motors in idle after a shutdown. Then i notice that after a minute or so the Phantoms motors starts spinning faster and faster from the idle speed, until it tryes to take off and tips over. I can counteract it by taking the throttle all the way down. But if i leave the trotlle again in the middel it goes faster, again. This never happens before a flight, only after.

    Any idea to what is causing this issue?

    All firmware updated. IMU cal before every flight. Phantom Vision.

    Try recalibrating your sticks in Naza.

    I had this happen as well. I found that there is a spot in the TX where if I push down it will go down further than where it rests. when I calibrate it ensure I am sensitive on the bottom of the throttle. Mine did not throttle up higher and higher and higher. It was just not shutting down or would rev up slightly. A re-calibration with this in mind solved the issue.
