    The motor order is defined in the Airframe Reference > Quadrotor x

That's it! The final build is shown below:

Finished Setup

Vehicle Configuration/Calibration

QGroundControl is used to install the PX4 autopilot and configure/tune it for the frame. Download and install QGroundControl for your platform.

Full instructions for installing and configuring PX4 can be found in Basic Configuration.

First update the firmware and airframe:

  • Firmware
  • Airframe

    You will need to select the Generic Quadrotor X airframe (Quadrotor x > Generic Quadrotor X).

    QGroundControl - Select Generic Quadrotor X airframee

Then perform the mandatory setup/calibration:

Ideally you should also do:

Tuning

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.
