Welcome to the NakeX 2.5 Frame Build Manual. This guide will walk you through the complete assembly process step by step.
• Install M2x22 mm standoffs using M2x6 mm screws
• Ensure the press nut is oriented in the same direction as the standoffs
• Choose the correct FC-to-Air-Unit adapter for your AIO flight controller
• The image shows both options
• (The lower adapter is shown upside down for demonstration purposes)
• Install the adapter on top of the AIO
• Install the TPU antenna mount on the rear standoffs
• Add the TPU spacers
• Ensure the antenna mount is oriented correctly, as shown above
• Install two M2x22 mm standoffs using M2x6 mm screws
• Ensure the press nuts face the same direction as the standoffs
• Push the two TPU camera mounts onto the standoffs
• Join both frame parts together
• Secure using M2x6 mm screws
• Do not tighten the camera mounts yet
• Install the GoPro mount
• Secure with two M2x8 mm screws
• Install the TPU wire mount
• Use one M2x8 mm screw through the third hole of the TPU GoPro mount
Congratulations! Your NakeX 2.5 V2 Frame is now fully assembled and ready for electronics installation.
• Install the standoffs onto the top plate
• Secure using M2x6 mm screws
• Install all motors
• Secure with M2x5 mm screws
• Apply conformal coating to the bottom side of the flight controller
• Only do this if you do not plan to solder anything additional like GPS or LEDs on that side
Tip: A UV lamp makes it easy to see where coating has already been applied. Be careful not to coat any connectors or plugs.
• Mount the FC using M2x12 mm screws
• Use the spacers supplied with the FC
• Ensure 1–2 mm clearance between the FC and the carbon plate
Direct contact with carbon fiber may short the FC and destroy it when powered.
• Pre-tin the motor wires and power pads
Soldering setup:
• Temperature: 450 °C
• Solder: TBS solder (recommended)
• Cut motor wires to length
• Ideal length: about mid-FC position when routed straight along the arms
• Leave a little slack to protect pads in a crash
• Strip approx. 2 mm insulation
• Twist and pre-tin the wire ends
• Tape the motor wires neatly to the frame
• Solder the wires to the ESC pads
• Trim capacitor legs to approx. 3 mm
• Solder 20 AWG wires to the legs
• Polarity:
– Short leg = –
– Long leg = +
• Insulate connections using shrink tube
• Solder the capacitor to the FC power pads
• Align it straight and centered on the plate, as shown
• Solder 16 AWG power wires to the FC
• Length should be slightly longer than the frame

• Cut the Naked Action Cam power wire to 10–11 cm
• Solder it to the FC power pads
This step requires precision — take your time to form a clean, shiny solder joint.
• Apply conformal coating to the top side of the FC
• Avoid all connectors and buttons
• Install the TPU XT30 mount on the rear standoffs

• Solder the PCB plate onto the male XT30 connector
• Cut power wires to length
• Solder them to the XT30 connector
• Apply liquid rubber to all exposed power solder joints
• Cut receiver wires to approx. 5 cm
• Solder the wires
• Bend the antenna slightly
• Cover everything with shrink tube
• Ensure the bind button remains accessible
• Install the receiver
• Apply shrink tube over:
– Capacitor
– Power wires
– Receiver
• Alternatively to shrinktube, tape can be used. If you decide to do this, wait until the VTX antennas are installed.
• Secure the assembly by screwing in the XT30 PCB plate
• Install the TPU VTX mount on the DJI O4 / O3 air unit
• Use M2x4 mm screws
• Mount the VTX on top of the FC
• Remove the four screws from the O4 air unit
• Carefully lift the cover
• Remove the U.FL antenna connectors
These connectors are extremely delicate — proceed slowly.
• Push the antennas through the TPU mount and shrink tube
• Using pliers to gently open space can help
• Reconnect the antennas
• Reinstall and secure the O4 top cover
• Push the TPU rear spacers into place
• Install the O4 camera into the TPU camera mount
• Use a zip tie to shorten excess cable for a clean layout
• Connect the O4 air unit to the FC
• Install the CFK bottom plate using M2x6 mm screws
• Route the receiver antenna between the rear standoffs
• Secure the receiver antenna to the frame using zip ties
• Install the TPU action cam mount
• Secure with M2x8 mm screws
• Cut battery pads into two thin, even strips
• Install lengthwise as shown
Benefits:
✔ Reduced weight
✔ Excellent battery grip
✔ Improved airflow to electronics
✔ Sexy
Congratulations! The major build work is complete. All that’s left is Betaflight configuration and minor ESC setup, install the props — and your NakeX 2.5 is ready to fly.
