"Webb13 maj 2002 · The aspect ratio isn't as important as the overall surface area. The vertical stab creates a moment arm about a yaw axis. As long as the moment arm is adequate, you'll have a very stable flier. For example, a short fuselage with large rudder is just as effective as a long fuselage with small rudder. Since you are planning on not using the ... " - Rudder aspect ratio
