Hello... I have small problem with autopilot.I try to make simulation on xplane9.Before I activate autopilot everything is good.But when autopilot is on ,plane flies strait forward and climbing slowly,instead of
flying to waypoints.Ardusimulator working properly.GPS and plane IMU datas
updating well.I couldn’t figured out what is the problem.Could you help me
plese???

As you can see from image.When I activate ardupilot , it adjust plane IMU roll=0 and Pitch=between
1.5 to 4.İt doesnt control heading.it gets fix when autopilot on condition.
