Tools needed
The following tools are used in this assembly:
- 2.0mm Hex screwdriver
- 3mm Phillips screwdriver
- Wire cutters
- Precision tweezers
- Soldering iron
组装
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.
The motor order is defined in the Airframe Reference > Quadrotor x

设置完成！ The final build is shown below:
PX4 Configuration
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, airframe, geometry, and outputs:
Airframe ::: info You will need to select the Generic Quadcopter airframe (Quadrotor x > Generic Quadcopter).
:::- Update the vehicle geometry to match the frame.
- Assign actuator functions to outputs to match your wiring.
- Test the configuration using the sliders.
Then perform the mandatory setup/calibration:
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:
调试
Airframe selection sets default autopilot parameters for the frame. These may be good enough to fly with, but you should tune each frame build.
For instructions on how, start from Autotune.
