I just got in a new HK APM 2.7 megapilot and a Quanum LEA-6H GPS . I positioned the APM with the forward arrow pointed forward and the arrow on the compass forward also. I removed the jumper to use the external compass. Using Mission planner the airplane is 180 degrees out, pointing in the wrong direction. Going back to initial setup the compass is set for no rotation. Changing that to 180 yaw the MP indicates the airplane is pointing in the correct direction.
Am I doing something wrong? Does the arrow on the GPS/Compass housing mean to point it forward? Check out the photo for position reference. Thanks
