I have calibrated the imu and compass multiple times on the Pixhawk 2 but the mission planner screen is indicating that the drone is flip as shown in the attached image.
Assuming your FC isn't mounted upside-down, have you checked the advanced configuration to see if the FC is listed as inverted? In Mission Planner go to CONFIG/TUNING and then Full Parameter List and then locate AHRS_ORIENTATION in the list (the default orientation value is 0, inverted is 8)
Once you're sure the value matches your FC's orientation then re-run the accelerometer calibration

Tested the drone with Pixhawk 2. Performed perfectly. Maybe its the drone build or the new Pixhawk 2 GPS; the position hold was very stable.
Awesome! Glad you got it sorted =)

Thanks. Yes that was the issue. Have changed the AHRS_ORIENTATION to '0' .
