Say I know this guy with a flying wing motor glider and he can get a much lighter engine than what was available to the designer 30 years ago. The pilot's back is already right up against the spar and he's got the battery as close to the trailing edge as it can get. So the only option to balance the plane with the new engine is to make the motor mount longer but this spreads the mass out along the longitudinal axis. I know that this will increase the inertia in pitch but I don't know how that affects the stability of a tailless airplane during normal flight and post stall.
