what method to use for hexacopter simulation?

Hey guys, im fairly new to matlab and wanted to know what method you would recommend me to use for modeling a hexacopter.

So for my bachelor thesis I will have to model a real hexacopter in a matlab simulation to see how it behaves in different weather conditions in the simulation. I tried the UAV Toolbox but it doesn´t really seem helpful or intuitive. should Ijust keep using Simulink or should I switch to matlab code or is there another better alternative? Which method is easier and makes more sense for this application?

Thanks in advance

Hi Eymen,

The following blocks might be helpful if you would like to model a hexacopter:

You might also need to use wind blocks to generate wind and use aerodynamic equations to compute drag on the hexacopter body:

Is there any way to connect these rotor propulsion blocks in a specific geometry, Like multi rotor has quad rotor+ and x geometries and can define arm lengths? I am also stuck at how to simulate hexacopter in Matlab using these blocks.

Any help is appreciated!

This is an example showing how to model tilt-rotor vehicle https://www.mathworks.com/help/uav/ug/customize-vtol-configuration.html. The rotors section in this example shows how to configure rotor arm
