Drone disarms instead of takeing off

My drone takes off normally when useing an RC remote, but when i try to plan a mission this happens.
I plan the simplest mission, one waypoint is take off, the other land.
I upload the waypoints and set up everything.
When i start the mission the drone arms with no problem.
The motors start spinning and the messeges say takeoff three times.
The drone doesnt take off and disarms.
I have no idea what is happening.
Any help much apprecieated.

You have to increase throttle on the RC to start a mission.

Well, not using the RC is the point, i want to start without it.

Then look at the AUTO_OPTIONS parameter.
