Want to customize the default x500 model in the gazebo simulation

[JustinGao20]

Hi developers,
We are currently working on a px4 project but we need to verify the simulated results before we want to deploy it on the real drone. However, a problem has come to our mind that our drone has a different parameter list as compared to the default holybro gx500 flight parameters. I am just wondering whether we could change the default parameters so that it will match up with the physical properties for our own drone.
We have found out that there are two folders in this repo. The sdf file in the x500 will help us change motor related parameters, and the sdf file in the x500_base will help use change the motor position and other properties. I am just wondering whether you could give us a more detailed explanation on the parameters in the gazebo files so that we could change them. Sincerely.
