1. In the other very well-discussed thread on the turning effect
produced during banking, it was pretty much clear that yaw is almost
inevitable during a bank. So what use the rudder at all? Or even the
tail - surely not merely to house the elevators??

2. Is there any advantage or disadvantage in having engines attached
to the fuselage near the tail section vis-a-vis under the wings? I'd
imagine banking would feel a lot lighter and enjoyable if the engines
weren't there

Education welcome, even if the Qs aren't
