| 5. Release the roll and pitch sticks and switch the CH7 switch high for at least 1 second. The words "Trim saved" should appear in the MP's Flight Data screen's Messages tab | ||
| 5. Arm the vehicle and lift into a hover. Flip the switch that you setup to its high position (>1800us). |

| 8. Take off again in stabilize mode and check if your copter is flying level now. If not repeat steps 4 - 7 again. |

| You can manually set the trim by modifying the :ref:`AHRS_TRIM_X <AHRS_TRIM_X>` and :ref:`AHRS_TRIM_Y <AHRS_TRIM_Y>`. Roll trim is :ref:`AHRS_TRIM_X <AHRS_TRIM_X>`, Pitch trim is :ref:`AHRS_TRIM_Y <AHRS_TRIM_Y>`. Both values are in radians with left roll and forward pitch being negative numbers. | ||
| 2. Set the CH7 Option to Save Trim on the Software > Copter Pids screen and press the "Write Params" button |

| 3. With your CH7 switch in the off position, fly your copter in Stabilize mode and use your transmitters's roll and pitch trim to get it flying level |

.. and once more replace "CH7" here.. or I guess at the top of the instructions we could specify to set RC7_OPTION = "5"

unfortunately, the videos had to be removed...perhaps Randy or I will remake them
the MP images are out of date also, but I don't think anyone will get confused, so I did not update them...
