Setting up the airframe configuration.
The HoverGames drone kit includes the LJI X4 500 drone frame. We previously used an S500 drone frame, for which a S500 airframe preset was available. Currently, we still use this with the LJI X4 500 frame.
In the airframe screen, under the Quadrotor X configurations, select the S500 airframe preset. The QGroundControl user guide provides more information on how you can select this airframe.
