Configuration 1 mockup phase
One critical aspect of this design is locating the 3D center of gravity. Mockups help me do that. With an asymmetrical configuration like this one, simply pointing the motor thrust lines through the C.G. isn't enough. You have to use some math. The vector equations for static equilibrium are written around a known C.G. Summation of forces on the Z axis and summation of moments about the C.G. must equal zero. That requires some trig.
