Hi @SHAURYA-PANTHRI ,
We don't have a model for Gazebo, but the frame is essentially a Holybro s500, and there may be some out there.
I've used JMAVSim a bit and it works well. We have a HIL tutorial here: https://www.youtube.com/watch?v=-uoIxAkiYtk
That might be a little overkill and software in the loop might work: https://dev.px4.io/v1.11/en/simulation/#sitl-simulation-environment
I'm actually pretty new to flying still. The m500 at first was intimidating for me (I'd come into the office early before everyone else so I could fly without any pressure haha ;). I bought a little toy $25 USD drone off amazon and flew that at home for a while, and then moving to the m500 was actually pretty easy!
