ruddervators
A butterfly, or Vee, tail, which combines the effect of the rudder and the elevators. These are movable surfaces. They cause the aircraft to pitch up or down when they move together and yaw when they move differentially.

The balance margin is so narrow that unbalancing could result from repainting the ruddervators without rebalancing afterward.
[delta] = [[[[delta].sub.th], [[delta].sub.ar], [[delta].sub.al], [[delta].sub.fr], [[delta].sub.fl], [[delta].sub.er], [[delta].sub.el]].sup.T] is the control input vector, which includes the throttle, the right aileron, and left one, similarly, followed by flaps, the ruddervators (V inverted tails).
The US Navy's MQ-4C Triton differs from the RQ-4B basically in equipment, but the wing and "ruddervators" are modified to avoid flutter at the relatively high airspeeds used in descending to low altitude to investigate surface contacts.
A boom operator, sitting in the old tail gunner's position, could actually "fly" it via a small wings termed "ruddervators." The receiver aircraft maneuvered behind the tanker and flew formation; the boomer would then fly his probe into the other aircraft's receptacle.
Going back to Bonanzas for an example, the V-tail models have a push rod actuating the ruddervators. The "normal"-tail versions use a similar linkage.
Recent tests have focused on natural icing trials, which have led Cirrus to add a pneumatic de-icing boot with a urethane material on the leading edges of the wings and ruddervators, as well a bleed air system for the electrically heated engine inlet for ice shedding.
The ruddervators are the primary control surfaces for both pitch and yaw and are made of aluminum, and each has a large trailing edge pitch trim tab.
The balance margin is so narrow that unbalance could--and has--resulted from repainting the ruddervators without rebalancing afterwards.
The two major variations of "ruddervators" resulted in final ADs, one for 1947-1950 models and the other for subsequent models.
In a world where a Cirrus CA.PS parachute repack starts at $10,000 and reskinning a couple of ruddervators on your Bonanza can be breathtaking, spending around $40,000 to get what amounts to a zero-time airframe, plus modern urethane paint that.
The big news here was the engine: The C33A was fitted with the V35 Bonanza's 285 HP Continental IO-520-B/BA, making it for all intents and purposes a straight-tailed Bonanza (although Bonanza purists maintain a "straight-tail" Bonanza is one of the early V-tail models, with narrow-chord ruddervators).
