WARNING! Set the drone on a flat surface before connecting the battery to accurately calibrate the sensors. Poorly calibrated sensors cause drones to fly erratically.
The sensors calibrate automatically each time the battery is plugged in. When the noises go quiet, the calibration is complete and the Riot is ready to fly. Brand new LiPo batteries typically come at storage voltage (3.85V per cell), so be sure to fully charge the LiPo before flying.
One way of troubleshooting erratic flight is to land the drone and recalibrate the sensors using stick commands. Throttle down and left while pitching back to calibrate the gyro sensor.
Throttle up and left while pitching back to calibrate the accelerometer.
