Hi all,  
is it possible to create my own multicopter model using Gazebo (defining weight, environmental conditions) and perform SITL simulation using PX4? There exists some examples?

Thank you,  
Valentina

Yes it’s possible and if you want to use Gazebo, you have lots of examples here: [https://github.com/PX4/sitl\_gazebo/tree/master/models](https://github.com/PX4/sitl_gazebo/tree/master/models). I also advise you to go through [https://dev.px4.io/en/simulation/gazebo.html](https://dev.px4.io/en/simulation/gazebo.html) so it’s clear to you how everything is setup and plugged.

Great! Thank you! If I would like to make one from the scratch, what tools do you suggest me to use?
