OK Mark, looking at things in reverse.....if you can add the vectored resultant of the models' speed to the props' rotational speed...then shouldn't you be able to do the same in reverse? Or only if the model is in a roll to the starboard side? [sm=bananahead.gif]
I don't understand your question. Because vectors have both force and direction, you can work backwards to get any of the three terms if you have the other two. But you seldom have the overall tip speed and not one of the other numbers...
