To me, pilots that are worried about "scale looks" only see the differences when the plane is sitting in front of them on the ground where you can squint and look for small details. If you are interested in actually flying the plane then why should you care bbecause once the plane is farther than 20 feet away from you, you can't see the engine sticking out anyway. Sideways mounted engines usually don't give you any more problems than vertical mounting which means fairly reliable runs for flying. Its definitely less nerve racking to fly with an engine that runs well and thats what you want. [8D]
