Sideways engine?

[george kennie]

John,
I'm not sure if I'm right on this, but I think that I would like to have
all that Mass(bulk & weight of the engine head) located on the
centerline of the aircraft.I think that all that off-center mass could
produce some unexpected and unwanted effects during snap type
maneuvers(and probably others) where radical changes in aircraft speed
differentials might magnify the off-center forces in a detrimental way
causing exagerated pitch and roll responces making control during
certain maneuvers difficult to compensate for. I don't have any
empirical data to back any of this up, but it just doesn't feel right to
me.
