&lt;p style=&quot;-qt-paragraph-type:empty; margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px; font-size:8pt;&quot;&gt;&lt;br /&gt;&lt;/p&gt;

&lt;p style=&quot; margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;&quot;&gt;&lt;span style=&quot; font-family:'Ubuntu'; font-size:11pt;&quot;&gt;This allows a certain amount of correction of those bias variations against temperature changes. It does improve both altitude hold and yaw performances.&lt;/span&gt;&lt;/p&gt;

Wait until completed.&lt;/span&gt;&lt;/p&gt;&lt;/td&gt;&lt;/tr&gt;&lt;/table&gt;&lt;/body&gt;&lt;/html&gt;</string>
