so, you want to make a beech bananza, or some fancy jet bomber.

Wikipedia Description:
In aircraft, a V-tail or Vee-tail (sometimes called a Butterfly tail) is an unconventional arrangement of the tail control surfaces that replaces the traditional fin and horizontal surfaces with two surfaces set in a V-shaped configuration when viewed from the front or rear of the aircraft. The aft edge of each twin surface is a hinged control surface (sometimes called a ruddervator) which combines the functions of both elevators and rudder.

     Making the V is very simple, not really worth telling you how.

but programming it is a bit difficult at times when you want to have it Yaw and Pitch at the same time, which is why im making this post.
When making the control surfaces your going to need 2 control surfaces of the same size on each side of the V, one on the top and bottom, the ones the top will be your Pitch, and the bottom 2 will be your Yaw. when assigning the Pitch surfaces, you want them deflecting inward, towards the Fusealage, once you got that going, your done with your Pitch. At this point the lower surfaces may be set to Roll, Pitch, or Yaw (depending on what wing you placed) your going to want to set that to yaw, go into the level and yaw left (or right) on the controls and make sure both lower surfaces are deflecting left (or right).
At this point you have finished, Good luck!

In the mid-1980s, the Federal Aviation Administration grounded the Beechcraft Bonanza due to safety concerns. While the Bonanza met the initial certification requirements, it had a history of fatal mid-air breakups during extreme stress, at a rate exceeding the accepted norm. The type was deemed airworthy and restrictions removed after Beechcraft issued a structural modification as an Airworthiness Directive.
