Cityflitzer DIY Manual

In this manual, we will guide you through the complete build process of the Cityflitzer drone.

Safety Notice This is not a toy. Fly responsibly and always follow proper safety procedures. When working on the bench:

Never install propellers

Always use a smoke stopper

• Mount the TPU battery pads using M2 washers and M2x8mm screws

• Ensure the threaded inserts on the top plate are facing downwards

• Flip the top plate over

• Install the arms in the orientation shown above

• Install the middle plate

• Mount the TPU RX antenna mount using M2x8mm screws

• Mount the TPU VTX antenna mount using M2x8mm screws

• Push M2x20mm standoffs into the designated horizontal mounting holes

• Install the motors using thread locker

• Secure the motor wires firmly to the arms using tape

• Cut the capacitor legs down to approximately 2mm

• Solder wires to the capacitor legs

• Apply liquid rubber to all exposed solder joints

• Pre-assemble the side plates and TPU bottom cover

• Use M2x20mm standoffs and M2x4mm screws

• Use this assembly to measure correct wire lengths, do not fully mount yet

• Apply conformal coating to the bottom side of the FC

• Allow the coating to fully dry

• Mount the FC to the frame using M2x12mm screws

• Solder the motor wires to the FC

• Solder the main power wires to the FC

• Solder the capacitor to the FC

Important:

• Leave enough slack in the motor wires

• Ensure capacitor wires are the correct length

• The capacitor must fit into the TPU bottom cover with slight wire slack

Tip: Conformal coating is clearly visible under UV light.

• Solder RX wires with approximately 4cm wire length

• Bend the antenna slightly so the bind button remains accessible

• Heat-shrink the entire receiver assembly

• Mount the DJI O4/O3 Air Unit to the TPU VTX mount using M2x4mm screws

• Install the VTX on top of the FC

• Open the VTX housing carefully

• Disconnect the UFL connectors

• Route the antennas through the TPU VTX antenna mount

• Reconnect the antennas

• Close the VTX housing

• Connect the VTX to the FC

• Connect the receiver to the FC

• Install the RX antenna into the TPU RX antenna mount

• Install the pod onto the frame using M2x4mm screws

• Install the capacitor into its TPU mount

• Install the receiver into its TPU mount

• Install the VTX camera using M2x4mm screws • Close the Bottom TPU cover with a M2x8mm screw through the latch in the front.

• Install the matching TPU battery mount onto the top plate

• Use M2 washers and M2x10mm screws

• Solder the XT30 PCB board to the male XT30 connector

• Insert the XT30 connector into the TPU battery mount

• Cut the power wires to length

• Ensure wires are not under tension

• Strip and pre-tin the wire ends

• Solder the wires to the XT30 connector

• Secure the mount using M2x8mm screws

• Apply liquid rubber to all exposed solder joints

Congratulations! Your Cityflitzer build is almost complete.

All that’s left:

• Betaflight configuration

• Minor ESC settings

• Install propellers

And you are ready to rip!
