General theory needs moving to Helicopter
The info about angular momentum is all good, but isn't specific to this article. I think it should be merged into Helicopter or another article, and only a summary should be given here (possibly with a link to the other article or article section) Hertzsprung (talk) 12:06, 31 March 2008 (UTC)[reply]
If the discussion of angular momentum is too much for this article, then it will be too much for the Helicopter article. It should be summarized here with a link to the Angular momentum article using the {{Main}} template. --Born2flie (talk) 17:40, 3 April 2008 (UTC)[reply]
"Rotational maneuvering is a more complex topic with respect to these designs, and involves engineering beyond the scope of this article." - is it anything more complicated than rotation being accomplished by a speed differential between the rotors?
