MOI and props and gimbals

A common occurrence on RCG and other forums is to to refer to rotational propeller physics as "inertia" whereas the poster really means to refer to moment of inertia. I myself am guilty of casually interchanging the terms on a regular basis but when I'm feeling like I'm in an exacting mood, I will use the correct terminology.

Moment of inertia has a few aliases/abbreviations, among them are:
  • rotational inertia
  • MOI
  • mass moment of inertia

The same misnomer is often applied to the discussion of gimbal axes where the posters are describing a gimbal axis resistance to rotation as inertia, where they actually mean to say MOI.
