Topaz' example was just an arbitrary value chosen because of it's familiarity. As for a surface canted more toward horizontal, that would probably be correct since both sides contribute to the projected vertical plane, so each side need only enough vertical to account for half the rudder area. A further advantage to this is that the opposing/cancelling forces I mentioned earlier are reduced with this configuration. However, I can see a situation where the projected area may be sufficient, but the effectiveness is too limited due to being too close to horizontal.tin response to Topaz, i have read that people are having the v tail at 35 degrees from horizontal, but in my mind, you woul want them at 45 degrees.. whats best?
