I’m making quadtailsitter in gz garden. I’m currently making it by referring to the aircraft in gazebo-classic. The problem with airspeed sim was solved by accepting the firmware as airspeed data in the z-axis direction, and the flight test was completed up to the multicopter mode. However, if the transition proceeds, the altitude of the aircraft continues to rise, flying unstable, and if the back transition is performed, the aircraft crashes. I think there is a problem with the advanced lift. I will leave the log as a link and proceed similar to the current gazebo-classic version.
