I have often wondered about inertia and twins in general:

with the engines off the centerline was it harder to get a twin into a
roll, and harder to stop?

Saying nothing of P effects, and torque, it is the fact that a object with
most of it's weight at the center is easier to spin. Think of the figure
skater pulling the arms in. She started with arms out, slowly. Arms in,
the same energy spun her faster.
