2 thoughts on “Moment of Inertia of the Quadcopter”
I am currently working on a project in which I am designing a quadcopter model. The physical model is complete but I am working on analysis of our design. I am curious to see the excel code used in the above spreadsheet and was wondering if you could post it. Thanks for your help.
i followed a decomposition of the quad into several known shapes (rectangular ,cuboid etc..) .
Then i applied the Parallle axis theorem to move all the COG of each decomposed parts to the center of the quad.
same approach for the propeller .
