To launch the Scout in Auto mode, first make sure there is a Takeoff waypoint programmed. It should use an angle of 40 degrees and an altitude at least two times the height of nearby obstacles.
Once the preflight checklist is complete, proceed to a location free of obstacles and face directly into the wind. In mode FBW-A, arm the Pixhawk and do one last check of the servos. Hold the Scout above your head with your index finger in the finger hold and using your other fingers to stabilize. Using your left hand, switch to Auto mode. Pixhawk will delay 4 seconds and then start the motor. Wait until the motor is turning and throw the Scout forward at about a 20 degree incline relative to level.
