butterfly tail
An arrangement whereby two surfaces forming a high dihedral perform the function of conventional horizontal and vertical tail surfaces (i.e., elevator and rudders). This permits easier recovery from spins besides being more effective, more responsive, and lighter than the conventional arrangement. Also called a V-tail.
