Rotational dynamics (def):
The dynamics resulting from a Zukerman quest for clarification or understanding, that when fully explained or answered, results in yet another example of his point without any form of acknowledging the original responses. Hence, around we go again, thus the term "rotational".
Example: Lu asks/states the R44 has a dangerously unstable rotorhead design. Delta3 kindly maths models the solution, explains it in depth, and comes up with proof that Lu's statement is unsupported. Lu reacts not by acknowledging the explaination, questioning the maths model, nor even the assumptions. Instead he replies..
Here is another point.
Rotational Dynamics at it's very best.
