I am developing a rotor blade with many rotors, I have been utilizing the use of the parent reference frame for all of my rotors. However, I have now been wondering why the examples utilize this. Each of the rotors are set up as a revolute joint spinning around the Z axis. Does this not cause it to spin around he Z axis relative to the parent, aka the center of the aircraft rather than the center of the rotor?
