The following tools are used in this assembly:
- 2.0mm Hex screwdriver
- 3mm Phillips screwdriver
- Wire cutters
- Precision tweezers
- Soldering iron
Estimated time to assemble is approximately 90 minutes (about 45 minutes for the frame and 45 minutes installing the autopilot and configuring the airframe.
-
Attach the 4 arms to the bottom plate using the provided screws.
-
Solder ESC (Electronic Speed Controller) to the board, positive (red) and negative (black).
-
Solder the Power Module, positive (red) and negative (black).
-
Plug in the motors to the ESCs according to their positions.
-
Attach the motors to the corresponding arms.
-
Add the top board (screw into the top of the legs).
-
Add double-sided tape (3M) to the CUAV V5+ flight controller (it has internal vibration damping, so no need to use foam).
-
Attach the FrSky receiver to the bottom board with double-sided tape.
-
Attach the telemetry module to the vehicle’s bottom board using double-sided tape.
-
Put the aluminium standoffs on the button plate.
-
Plug in Telemetry (
TELEM1) and GPS module (GPS/SAFETY) to the flight controller.
-
Plug in the RC receiver (
RC), all 4 ESC’s (M1-M4), and the power module (Power1) into the flight controller.

设置完成！ The final build is shown below:
QGroundControl is used to install the PX4 autopilot and configure/tune it for the frame. Download and install QGroundControl for your platform.
:::tip Full instructions for installing and configuring PX4 can be found in Basic Configuration. :::
First update the firmware and airframe:
-
Airframe :::note You will need to select the Generic Quadrotor X airframe (Quadrotor x > Generic Quadrotor X).
:::
Then perform the mandatory setup/calibration:
-
:::note For this build we set up modes Stabilized, Altitude and Position on a three-way switch on the receiver (mapped to a single channel - 5). This is the recommended minimal set of modes for beginners. :::
Ideally you should also do:
Firmware installation sets default autopilot parameters that have been configured for the selected frame. These are good enough to fly with, but it is a good idea to tune the parameters for a specific frame build.
