Actually, there is nothing wrong with using a rotating reference frame.
There are some differences from an inertial one (e.g. the apperance of a
centrifugal force) but both are valid and workable. Rotating (semi)rigid
objects can often be treated more easily in a rotating reference frame.

This is way off topic btw. :)
