       <long_desc>This compensates for voltage drop of the battery over time by attempting to normalize performance across the operating range of the battery. The copter should constantly behave as if it was fully charged with reduced max acceleration at lower battery percentages. i.e. if hover is at 0.5 throttle at 100% battery, it will still be 0.5 at 60% battery.</long_desc>

       <long_desc>The D-term uses the derivative of the rate and thus is the most susceptible to noise. Therefore, using a D-term filter allows to decrease the driver-level filtering, which leads to reduced control latency and permits to increase the P gains. A value of 0 disables the filter.</long_desc>
