PX4 SITL-Gazebo Harmonic: Modify physical properties

Hello all,

I have a question about PX4 SITL and Gazebo harmonic. I am reaching out to ask for your guidance on the critical elements I should modify to ensure my simulation runs correctly.

Specifically, I want to simulate an Octorotor Coaxial. I modified the x500 quadrotor configuration and added four more motors. I also modified the .param file. It takes off and hover stably.

After that, I tried to increase the weight, inertia of the drone and propellers’ weight and size. The drone only takes off at 0.8m and does not reach the desired altitude. I also increased the maxRotvelocity but the problem persists.

Can you help and provide information on how can I do this? If there is anyone that could help I will upload the sdf file to replicate. Thank you in advance.
