CPO Symmetrical Tricopter and T-Copter Design Theory and Defining Optimum Center of Gravity Location

In this video, I discuss what I have learned with regard to basic symmetrical tricopter and t-copter design. I show how the tricopter and the t-copter are the same from the flight controller’s perspective, and from the perspective of a symmetrical build design. I show how to identify the location of the desired Center of Gravity (COG) point for this type of design. I also show how to identify the proper rear motor position (via rear boom length) for given front motor positions. Oh..and I show how how this T-Copter calculator works just a well for tricopters…and how it validates my “circular” logic of tricopter symmetry.


I am still designing my tricopter, and you can find my design log at:
