Hmm... i rather wish the CCG was a bit more specific about it -_-;. It the NH-model android/gynoid comparison chart, it says 'limited' under gravitational/inertial control for Yamataians, as opposed to NH-29s, for which it says 'yes,' indicating that there is a significant difference in capability in this area between these two models. In the descriptive text for Yamataians, gravity control was also mentioned as one of the things that was being 'cut' from the Yamataian model to some extent. Unlike the NH-29, however, no hard stats are given...
