UAS Preparation – Camera Timing/Triggering Check

  • Connect an external GNSS antenna to the GNSS antenna port of the WLAN Connector.
  • Place both the UAV and the WLAN Connector under open sky GNSS conditions. 
  • Open MAVinci Desktop. Create/Open a session. 
  • Power on and Connect to the WLAN Connector and UAV in MAVinci Desktop.
  • Allow both the WLAN Connector and UAV to track GNSS satellites for approximately 10-15 minutes. Configure the Internal Base RTK and stream RTK corrections to the UAV.  
  • Create a new flight plan (i.e. basic polygon, terrain, etc.) near where the UAV and WLAN Connector are currently located on the Map View. 
  • Select Edit – Recalculate Flight Plan
  • Select Flight Plan – Transmit Flight Plan to plane.
  • Select Ok to the Check Wing Connection window that appears. 
  • Confirm that the flight plan has been transmitted to the UAV.
  • Open the camera compartment of the UAV.
  • Insert the camera SD card.
  • Close the camera compartment of the UAV. 
  • Roll the UAV fuselage 60 degrees. Confirm that the UAV camera triggers an image. The sound of the UAV camera triggering will be audible. 
  • Collect 10 images with the UAV rolled 60 degrees.
  • Open the camera compartment of the UAV and remove the camera SD card. 
  • Insert the camera SD card into the user’s PC. Confirm that the 10 images triggered are stored to the SD card.
  • Confirm that current UTC time is associated with each image taken.
  • Once finished, power off both the WLAN Connector and UAV and remove the LiPo battery from the UAV cockpit. 

Control Surface Check (Assembly)

  • For details on aircraft assembly, please refer to the UAV assembly checklist in section 4.2.2 of the MAVinci user’s manual.
  • Remove the UAV fuselage from the transport case.
  • Remove the plastic sleeve around the fuselage. 
  • Prepare four airfoil screws and fasteners and a flathead screwdriver. 
  • Remove the vertical and horizontal stabilizer from the transport case.
  • Pick up the UAV fuselage and with the nose of the aircraft firmly placed onto the user’s shoe (and not the ground), attach the vertical stabilizer to the fuselage.
  • Attach the horizontal stabilizer to the UAV fuselage ensuring that there is no gap between the bottom of the horizontal stabilizer and the UAV fuselage.
  • Insert 2x airfoil screws and fasteners through the holes located on the bottom of the horizontal stabilizer.At first, hand tighten the screws, then using the flathead screwdriver, secure both stabilizers to the UAV fuselage. Do not overtighten the screws.
  • Confirm that the horizontal and vertical stabilizers are firmly attached and secured to the fuselage:
    • There should be little to no movement when moving the horizontal stabilizer back and forth. Adjust the screw tension as necessary using ½ turns.
    • There should be no gap between the bottom of the horizontal stabilizer and the UAV fuselage.  
  • Connect the electrical connectors for the horizontal and vertical stabilizers to the fuselage.​​

Control Surface Check (Assembly) - continued

  • Remove the left and right wing connector tube from the top foam insert of the transport case. 
  • Using a measuring tape, locate the center of the wing connector tube. Mark the center using a marker or small piece of white duct tape. 
  • Remove the left and right wings of the UAV from the transport case.
  • Insert the wing connector tube into either wing until the center of the tube is reached. Repeat this process for the remaining wing so that half of the wing connector tube is inserted into both wings. 

Control Surface Check (Assembly) - continued

  • Place the leading edge of both wings flush with the rear of the UAV cockpit.
  • Insert 2x airfoil screws and fasteners through the holes located on the top of the wings.
  • At first, hand tighten the screws, then using the flathead screwdriver, secure both wings to the UAV fuselage. Do not overtighten the screws. 
  • Confirm that both wings are firmly attached and secured to the fuselage. 
    • Pickup the UAV by the leading edge of both wings.
    • With the nose of the UAV facing the user and 2-3 inches away, swiftly twist the aircraft back and forth in the direction of yaw.  
    • There should be very little to no movement between the wing and fuselage assembly. Adjust the screw tension as necessary using ½ turns. 
  • Connect the electrical connectors for both wings to the UAV fuselage.
    • Left wing electrical connector to the left connector on the UAV fuselage. Right to right. 

Control Surface Check (RC)

  • Remove the motor security lock band around the propellers and remove the UAV cockpit canopy.
  • Power on the UAV by placing a charged LiPo battery into the cockpit, secure with the battery strap, and connect the LiPo battery cable.
  • Replace the UAV cockpit canopy and replace the motor security lock band around the propellers.
  • After powering on the UAV, all the servos for the wings and stabilizers will power on and be audible. 
  • Switch the RC controller into full manual mode. Confirm the following:
  • The right throttle stick is fully down.
  • The yellow toggle switch is set to Automatic.
  • The red toggle switch is set to Manual.
  • Power on the RC controller. After powering on the RC, all the servos for the wings and stabilizers will no longer be audible.
  • Move the left control stick left and right. Confirm the servo for the vertical stabilizer responds to the RC controls and the stabilizer is able to move freely.
  • Move the left control stick up and down. Confirm the servo for the horizontal stabilizer responds to the RC controls and the stabilizer is able to move freely.
  • Move the right control stick left and right. Confirm the servos for both ailerons respond to the RC controls and the ailerons are able to move freely.
  • Power off the RC controller.

Control Surface Check (RC)

  • Open MAVinci Desktop. Create/Open a session. 
  • Power on the WLAN Connector and Connect to the WLAN Connector and UAV. 
  • Confirm the UAV status information on the Map View reports an RC Link Failure error.
  • Power on the RC controller.
  • Confirm that the RC Link failure error disappears.
  • Disconnect from the WLAN Connector and UAV. 

Control Surface Check (Disassembly)

  • For details on aircraft disassembly, please refer to the UAV disassembly checklist in section 4.2.8 of the MAVinci user’s manual.
  • Remove the motor security lock band around the propellers and remove the UAV cockpit canopy.
  • Disconnect and remove the UAV LiPo battery. 
  • Replace the UAV cockpit canopy and replace the motor security lock band around the propellers.
  • Power off the RC controller. 
  • Disconnect both wing electrical connectors from the UAV fuselage. 
  • Using a flathead screwdriver, remove the airfoil screws and fasteners used to secure the wings. 
  • Pickup the wings off the UAV fuselage via the leading edge and pull the left and right wings apart.
  • Return the left (or right wing) to the transport case.
  • Remove the wing connector tube from the remaining wing and return it to the transport case.

Control Surface Check (Disassembly) - continued

  • Return the remaining wing to the transport case.
  • Pick up the UAV fuselage and firmly place the nose of the fuselage onto the user’s shoe.
  • Disconnect the electrical connectors for the horizontal and vertical stabilizers.
  • Using a flathead screwdriver, remove the airfoil screws and fasteners used to secure the stabilizers
  • Return the horizontal and vertical stabilizer to the transport case.
  • Replace the plastic sleeve around the fuselage and return the UAV fuselage to the transport case.
  • Return the RC controller to the transport case. 
  • Return the WLAN connector to the transport case.
  • Return all airfoil screws and fasteners to the transport case.
