2. Insert M3x12 screws (Cell 7) into the outer holes of the lower frame plate. Insert M3x30 screws (Cell 6) into the central holes of the lower frame plate.

   

   Assembling the frame

   
   

3. Install M3 press-fit nuts (Cell 1) into the designated holes on the intermediate frame plate. Tighten the screws installed in the previous step until the frame arms are securely fastened.

Caution

Ensure the screws do not protrude into the motor winding area. Too long screws can damage the windings and cause a short circuit.

3. Install the Electronic Speed Controller (ESC) onto the M3x30 screws (Cell 6) on the intermediate frame plate. Route the battery power contacts toward the rear of the frame.

   

   ESC mounting

   
   

4. Install wire protectors and route the motor wires through them. Solder the power wires and the capacitor to the ESC power contacts. Solder the motor wires to their corresponding contacts as shown in the wiring diagram.

Final Assembly

1. Install the ELRS radio receiver and connect it using the cable to the SBUS/CRSF port on the flight controller.

   

   Receiver installation

   
   

2. Install rear protective covers. To do this, hook the mounting tab behind the standoff near the flight controller, then snap the clip onto the rear standoff.

   

   Rear protection

   
   

3. Use double-sided adhesive tape to install the LED modules to the inner sides of the arms.

   

   LED mounting

   
   

4. Connect the LED modules to the LED hub as shown in the image. Connect the hub to the LED/Buzzer port on the flight controller.

   

   Wiring

   
   

5. Route the LED module wires to ensure they are neither stretched tight nor positioned where they could interfere with moving parts.

   

   Wire management

   
   

6. Thread the battery strap through the designated slots, and install the top frame plate using M3x6 screws (Cell 9).

10. Before your first power-up, check the following:

• All components are securely fastened.

• All electrical connectors are correctly connected.

• No wires are damaged and no connectors are loose.

• The battery has no signs of swelling, overheating, or physical damage.

• The propellers have sufficient clearance and do not contact the guard, wires, or any other quadcopter elements.

Caution

Do not power on the quadcopter until all detected faults have been fully resolved.

Flashing Firmware

Before proceeding to software configuration, replace the PX4 firmware with Betaflight. Follow the procedure outlined in the Firmware Guide.

Software Setup

After firmware flashing is complete, perform the final system configuration by following the Setup Guide.
