Adding PX4 Vision model in Gazebo

edit

Hello Gazebo community, as part of my project, I am trying to import the PX4 Vision model on Gazebo (.stp file available online). After converting the .stp file to a .dae and separating the rotors, when I execute my launch file, the drone does not behave as I expect, and does a bit of a mess. At the moment I'm using the intelaero model in Gazebo, and it works well. I try to calculate or change the torque, trust, drag and moment constants, but I can't get the drone to fly correctly. Has anyone already imported the PX4 Vision model on Gazebo, or knows the values ​​of the constants?

Thank you for your help.
