Moments of inertia for an object, such as an aerial vehicle, may be determined by suspending the object from at least two filars, or cables, that are aligned in parallel and of equal length. After imparting a rotation upon the object about a vertical axis, data regarding oscillations of the object may be captured using an inertial measurement unit associated with the object. The captured data may be used to calculate a moment of inertia about the vertical axis, and to determine a vector corresponding to the vertical axis. After suspending the object, imparting rotations to the object and capturing data with the object in a number of orientations, a moment of inertia tensor may be calculated about the object's principal axes based on the moments of inertia about vertical axes in such orientations and the vectors.
