====== NakeX 2.5 Complete Build Manual ======

===== Step 1 – Top Plate & Standoffs =====
{{ :public:nakex_2.5_diy_buildmanual-1.jpg?nolink&600 |}}

• Install the standoffs onto the top plate

• Secure using M2x6 mm screws

===== Step 2 – Motor Installation =====
{{ :public:nakex_2.5_diy_buildmanual-3.jpg?nolink&600 |}}

• Install all motors

• Secure with M2x5 mm screws

===== Step 3 – Conformal Coating (Bottom Side) =====
{{ :public:nakex_2.5_diy_buildmanual-5.jpg?nolink&600 |{{ :public:nakex_2.5_diy_buildmanual-5.jpg?nolink&400|}}

• 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.

===== Step 4 – Install Flight Controller =====
{{ :public:nakex_2.5_diy_buildmanual-7.jpg?nolink&600 |}}

• 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)

===== Step 5 – Motor Wire Preparation =====
{{:public:nakex_2.5_diy_buildmanual-9.jpg?nolink&400|}} {{ :public:nakex_2.5_diy_buildmanual-10.jpg?nolink&400|}}

• 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

===== Step 6 – Motor Wire Soldering =====
{{ :public:nakex_2.5_diy_buildmanual-15.jpg?nolink&600 |}}

• Tape the motor wires neatly to the frame

• Solder the wires to the ESC pads

===== Step 7 – Capacitor Preparation =====
{{ :public:nakex_2.5_diy_buildmanual-16.jpg?nolink&600 |}}

• Trim capacitor legs to approx. 3 mm

• Solder 20 AWG wires to the legs

• Polarity:

– Short leg = –

– Long leg = +

• Insulate connections using shrink tube

===== Step 8 – Capacitor Installation =====
{{ :public:nakex_2.5_diy_buildmanual-19.jpg?nolink&600 |}}

• Solder the capacitor to the FC power pads

• Align it straight and centered on the plate, as shown

===== Step 9 – Main Power Wires =====
{{ :public:nakex_2.5_diy_buildmanual-21.jpg?nolink&600 |}}

• Solder 16 AWG power wires to the FC

• Length should be slightly longer than the frame

===== Step 10 – Naked Action Cam Power =====
{{:public:nakex_2.5_diy_buildmanual-24.jpg?nolink&400|}}{{ :public:nakex_2.5_diy_buildmanual-25.jpg?nolink&400|}}
{{ :public:nakex_2.5_diy_buildmanual-28.jpg?nolink&600 |}}

• 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.

===== Step 11 – Conformal Coating (Top Side) =====
{{:public:nakex_2.5_diy_buildmanual-29.jpg?nolink&400|}} {{ :public:nakex_2.5_diy_buildmanual-30.jpg?nolink&400|}}

• Apply conformal coating to the top side of the FC

• Avoid all connectors and buttons

===== Step 12 – TPU XT30 Mount =====
{{ :public:nakex_2.5_diy_buildmanual-32.jpg?nolink&600 |}}

• Install the TPU XT30 mount on the rear standoffs

===== Step 13 – XT30 Connector Preparation =====
{{:public:nakex_2.5_diy_buildmanual-33.jpg?nolink&400|}}{{ :public:nakex_2.5_diy_buildmanual-34.jpg?nolink&400|}}

• Solder the PCB plate onto the male XT30 connector

===== Step 14 – XT30 Power Wiring =====
{{ :public:nakex_2.5_diy_buildmanual-36.jpg?nolink&600 |}}

• Cut power wires to length

• Solder them to the XT30 connector

===== Step 15 – Insulation =====
{{ :public:nakex_2.5_diy_buildmanual-38.jpg?nolink&600 |}}

{{:public:nakex_2.5_diy_buildmanual-40.jpg?nolink&400|}} {{ :public:nakex_2.5_diy_buildmanual-41.jpg?nolink&400|}}

• 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

===== Step 17 – Receiver Installation =====
{{ :public:nakex_2.5_diy_buildmanual-43.jpg?nolink&600 |}}

• 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

===== Step 18 – TPU VTX Mount =====
{{ :public:nakex_2.5_diy_buildmanual-44.jpg?nolink&600 |}}

• Install the TPU VTX mount on the DJI O4 / O3 air unit

• Use M2x4 mm screws

===== Step 19 – VTX Installation =====
{{ :public:nakex_2.5_diy_buildmanual-46.jpg?nolink&600 |}}

• Mount the VTX on top of the FC

===== Step 20 – O4 Antenna Modification =====


{{ :public:nakex_2.5_diy_buildmanual-49.jpg?nolink&600 |}}

• 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.

===== Step 21 – Antenna Routing =====
{{ :public:nakex_2.5_diy_buildmanual-51.jpg?nolink&600 |}}

• Push the antennas through the TPU mount and shrink tube

• Using pliers to gently open space can help

===== Step 22 – Reassembly =====
{{ :public:nakex_2.5_diy_buildmanual-55.jpg?nolink&600 |}}

• Reconnect the antennas

• Reinstall and secure the O4 top cover

===== Step 23 – Rear TPU Spacers =====
{{ :public:nakex_2.5_diy_buildmanual-57.jpg?nolink&600 |}}

• Push the TPU rear spacers into place

===== Step 24 – Camera Installation =====
{{ :public:nakex_2.5_diy_buildmanual-53.jpg?nolink&600 |}}

• Install the O4 camera into the TPU camera mount

• Use a zip tie to shorten excess cable for a clean layout

===== Step 25 – Final Connections =====
{{ :public:nakex_2.5_diy_buildmanual-56.jpg?nolink&600 |}}

• Connect the O4 air unit to the FC

===== Step 26 – Bottom Plate =====
{{ :public:nakex_2.5_diy_buildmanual-58.jpg?nolink&600 |}}

• Install the CFK bottom plate using M2x6 mm screws

• Route the receiver antenna between the rear standoffs

===== Step 27 – Antenna Securing =====
{{ :public:nakex_2.5_diy_buildmanual-59.jpg?nolink&600 |}}

• Secure the receiver antenna to the frame using zip ties

• Install the TPU action cam mount

• Secure with M2x8 mm screws

===== Step 29 – Battery Pads =====
{{ :public:nakex_2.5_diy_buildmanual-61.jpg?nolink&600 |}}

• Cut battery pads into two thin, even strips

• Install lengthwise as shown

Benefits:
