| BAT_V_EMPTY | 0.9 | 100.0 | 3.2 | 1 | 1 | Voltage of an empty battery cell |
| BAT_V_FULL | 1.0 | 200.0 | 4.05 | 1 | 1 | Voltage of a full battery cell |
| BAT_N_CELLS | 1 | 100 | 3 | 1 | 1 | Number of SERIAL battery cells. Typically this ranges from 2S to 6S in small-scale UAVs |
| BAT_V_SCALING | 0.001 | 1.0 | 0.00838 | 1 | 1 | Conversion from ADC ticks to battery voltage. Depends on the connected board, calibrate with a multimeter. |
| MC_ATTRATE_P | 0.0 | 20.0 | 0.20 | 1 | 1 | Multirotor attitude rate control P gain. This gain controls how much of the motor thrust should be used to control angular velocity. A larger number will increase the control response, but will make the system also more twitchy. |
| FW_ROLLRATE_P | 0.0 | 20.0 | 0.30 | 1 | 1 | Fixed wing roll rate control P gain. This gain controls how strong the ailerons or rudder should be actuated in order to achieve a certain roll rate. A larger number will increase the control response, but will make the system also more twitchy. |

Gyroscope (GYRO) and Accelerometer (ACCEL) calibrations have to be performed with a static, unmoved system. The magnetometer calibration needs to be performed while moving the device.</span></p>
<p style=" margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;"><span style=" font-size:12pt;">Carefully follow the instructions. Click on MAG to start the calibration. Watch the communication console for further instructions (Available through Main Menu -&gt; Tool Widgets -&gt; Communication Console). Do not calibrate the vehicle in vincinity of metal, e.g. from a table or chair. Start the calibration, leave the system unmoved on the table. Wait for the double beep. Next move the system in a figure eight, roll and pitch it strongly and perform the figure eight also upside-down. The calibration is finished after the triple beep.</span></p>
<p style=" margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;"><span style=" font-size:12pt;">Put the system on an absolutely level surface and press ACCEL, wait for the the triple beep. Do not move the system. If no flat surface is available, rather not calibrate the system.</span></p>
<p style=" margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;"><span style=" font-size:12pt;">The orientation is not important for this calibration, but do not move the system until the triple beep or the matching text message in the console.</span></p></body></html></string>
