    3.6.1 POWERING ON THE H520-G Power on the H520-G first by gently inserting a battery into the rear of the H520-G while lifting the rear lever on the back of the battery pack. Push the battery all the way in and release the lever. Give one final push on the rear of the battery to ensure the battery is fully seated.
  • Page 27 Once the visual and auditory check has been performed, move the left stick upward, away from the pilot. Do not hesitate to add maximum throttle input. The H520-G will lift off the ground. When the H520-G is approximately 15-20 feet in altitude, release the left stick, the stick will center itself and...
  • Page 28 This is a good time to check the flight control systems. 3DR recommends checking pitch, yaw, roll and altitude before each flight. To check pitch, push the right stick upward and the H520-G will move away from the pilot. Pull the right stick downward and the H520-G will move towards the pilot.
  • Page 29 3.6.4 LANDING AND MOTOR SHUTDOWN When ready to land, fly the H520-G towards the launch/landing area. At an altitude of 12 ft/3.5M or higher, lower the landing gear using the button on the top right of the ST10C. Use the left altitude stick to slowly bring the H520-G down towards the landing point (turning the H520-G nose away from the pilot makes landing more intuitive on the right stick controls.) After the H520-G touches down, continue to hold the...
  • Page 30 The pilot may want to pause a mission to avoid obstacles or regain bearings. To pause an autonomous mission, tap on the Pause button in the Site Scan App or ST10C (Hover Button). This will cause the H520-G to hover and maintain its position. Moving any stick on the ST10C during an automated mission will also pause/hover the aircraft.

    4.2 BATTERY FAILSAFE During low battery flight mode, the H520-G will attempt to RTL. In some cases, the H520-G might be too far from the launch site to return. During low battery flight mode, the pilot has limited lateral control and no vertical control of the H520-G.

  • Page 32: Troubleshooting

    During RTL Mode the pilot may maneuver the H520-G to assist in automatic landings. As the H520-G nears the ground, the pilot should refrain from adjusting the controls as the H520-G may tip over when being maneuvered as the legs touch down.
