Hi
So it's to prevent it from rolling, right. But what's going to cause it to roll?

Hi Doug.
The reason for the tail is to provide a useful torque for pitching.
The V shape is to maximise rolling stability while reducing the
resistance to pitch.
The more torque, the more powerful the pitch and the less energy necessary.
This is all hand-wavey stuff of course.
