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

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.
