SAFETY SYSTEMS

Return To Land (RTL)

Pilot or controller

Battery failsafe 

Automatically Return to Home on low battery

Emergency Shutdown

(Hold the left stick down and tap the Arming button 4 times)

STICK CONTROLS

GET FAMILIAR WITH THE  REMOTE CONTROLLER

CHARGE THE BATTERIES

Make sure the batteries are firmly pushed into the battery slots. Charging the batteries using the DY5 multi-charger takes around 1 hour.

* Normal charger takes 2.5 hours to charge a single battery

Replace batteries every 200-250 cycles.

Vehicle setup

UNFOLDING THE AIRCRAFT

Gently lift the arms until a click is heard. Test the locks by gently lifting up and pressing down on the arms several times. To unlock the arms, press the PRESS button on the base of the arms.

MOUNTING THE GIMBAL AND CAMERA

Using the arrow on top of the camera gimbal pointed towards the H520-G, slide the camera gimbal (arrow towards the airframe) until the front latch clicks.

Gently pull the camera gimbal away from the aircraft to check proper installation, if the gimbal comes off the rail or is not solid and secure, remove the gimbal and install the gimbal again.

Firmware updates

Site Scan App:

Internet is required for the Site Scan Field app to download the update, we recommend doing it via WiFi:

  1. Power up the Controller, and connect it to the iPad via Lightning cable, turn the Vehicle ON
  2. Open the Site Scan App and select the H520-G vehicle
  3. Click the gear icon on the top-right corner to open the Global settings menu
  4. Go to Aircraft Settings > Firmware Manager
  5. Select Update Firmware
  6. Download and install the updates, wait for the drone to finish them and restart it
  7. Ensure the Firmware on the drone versions for Autopilot, Camera, Gimbal & RC match the Latest Firmware versions

Vehicle Calibrations

COMPASS CALIBRATION

  1. With the Drone powered ON, open the Site Scan App and select the H520-G vehicle
  2. On the Global settings menu, go to Aircraft Settings > Calibration > Compass
  3. A graphical grid will display with six boxes. Each box indicates what is required to calibrate the compass
  4. Pick up the H520-G by the two arms, with green dots, as close to the Arm joints as possible
  5. Rotate the H520-G in the direction indicated in the box highlighted in yellow
  6. Using the Arrow in the box to point towards the front of the H520-G (the front has the two sonar eyes), rotate the H520-G until it beeps
  7. Continue doing the same for the next box highlighted in yellow
  8. Upon successful completion of the Compass calibration, you will return to the
  9. Calibration menu and a green dot will be displayed next Compass
  10. A failed calibration will be indicated by all six arm lights on the H520-G blinking red
  11. If calibration fails, try again after moving the aircraft away from any metallic objects 

Note: Do not install the propellers until the calibration is completed. Having the propellers

installed may cause damage to the props, motors, or arms, or even minor physical injury to the user. 

ACCELEROMETER CALIBRATION

  1. With the Drone powered ON, open the Site Scan App & select the H520-G vehicle
  2. On the Global settings menu, go to Aircraft Settings > Calibration > Accelerometer
  3. A six-box grid will appear with the H520-G in different positions
  4. Place the H520-G on the ground as shown in the highlighted box
  5. After each position, the H520-G will give an audible tone and the
  6. highlighted box will change to the next position
  7. Upon a successful completion of accelerometer calibration, a green
  8. dot will appear next to the Accelerometer setting
  9. A failed calibration will be indicated by all six arm lights blinking red
  10. If fail, try again, being sure to not move the aircraft during calibration

Note: Do not install the propellers until the calibration is completed. Having the propellers installed may cause damage to the props, motors, or arms, or even minor physical injury to the user. 

GYRO CALIBRATION

  1. With the Drone powered ON, open the Site Scan App and select the H520-G vehicle
  2. On the Global settings menu, go to Aircraft Settings > Calibration > Gyro
  3. A graphical box will be displayed, indicating what is required to calibrate the gyro
  4. Position the vehicle as shown in the diagram until marked as completed
  5. Upon successful completion of the Gyro calibration, you will return to the
  6. Calibration menu and a green dot will be displayed next Gyro
  7. A failed calibration will be indicated by all six arm lights on the H520-G blinking red
  8. If calibration fails, position the aircraft on a flat, leveled surface and try the calibration again without moving the aircraft during calibration

Note: Do not install the propellers until the calibration is completed. Having the propellers

installed may cause damage to the props, motors, or arms, or even minor physical injury to the user. 

Tips and Tricks

PRACTICE FLYING MANUALLY

The foundation for a successful flight includes knowing how to control your drone.

We recommend to get familiar with the sticks by doing a test flight in a wide open area, free of obstacles and get familiar with the sticks.

FORMAT THE CAMERA

In order to keep a clean workflow, it is recommended to format the camera using Site Scan App. The instructions are below:

  1. Open Site Scan App
  2. Tap the gear icon on the top-right corner
  3. Go to Camera Settings
  4. Select Format Camera

WAIT FOR A GOOD GPS LOCK!

The vehicle only needs around 8 satellites to take off, but we recommend at least 13 satellites for the home position to be set with a good level of accuracy.

A good GPS lock is also needed for automatic flight modes to work properly, including Return to Land.

BATTERY RECOMMENDATIONS

Be certain to never completely drain an H520-G battery. Batteries should be stored at 30-50% charge, and

never stored at full charge.

The DY5 multi-charger for the H520-G battery is capable of discharging batteries, preparing them for storage.

Flight time is estimated to be approximately 25 minutes per battery (E90 camera).

Vehicle Calibrations (Compass/Accelerometer/Gyro)

PRIOR TO LAUNCHING THE H520-G (FIRST TIME), it is required that the Compass, Accelerometer and Gyro calibrations are performed. This is for safety and proper operation of the aircraft. See Calibration section for more information.

It is also highly recommended that the aircraft always be recalibrated after each software/firmware update.

Return To Land (RTL)

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.

Return to Land Mode will trigger an automatic landing; the pilot should be prepared to use the throttle stick to shut down the motors (keeping it all the way down), although the aircraft is expected to disarm/shut down motors on its own. 

Note: If landing manually, make sure to lower the gear before attempting to land, it will NOT extend automatically.

PAIRING TROUBLESHOOTING

Pairing the vehicle:

  1. Power up the Controller and connect it to the iPad via Lightning cable
  2. Open up the Site Scan App, login and select any Project
  3. Select the H520-G vehicle in the Site Scan App. Note that the telemetry status will show “Connecting”
  4. To access the binding menu go to:
  5.  “Global Settings” → “Aircraft settings” → “Remote Controller Pairing”
  6. Tap “Pair with Vehicle”
  7. Hold the H520-G upside down to start the binding process. The LEDs will start blinking yellow quickly. If it doesn’t work then the aircraft may need to be restarted.
  8. To test the vehicle was paired just try to pitch the camera, if it moves, it means that the drone is connected and you just need to bind the camera. 
  9. Camera pairing should begin after a successful vehicle pairing; the default password will automatically be typed in: 1234567890
  10. If the full pairing process is successful, the blue light on the front of the controller should stop blinking after a few seconds and become solid blue.
