Abstract
Stabilizers and their control surfaces are vital components in maneuvering an airplane during flight. However, a shortcoming of stabilizers is that they require airstream or propeller wash for them to work properly. In this work, we propose the concept of roto-stabilizer as viable substitution for conventional horizontal stabilizer. A key benefit of the proposed technique is its ability to exert powerful moment in the absence of forward airspeed or propeller wash. Proof of principle is demonstrated via computer simulations. Results reveal that new aerobatic maneuvers are made possible. Furthermore, when implemented in canard configuration, it is possible to achieve ultra-STOL and VTOL.

Stabilizing fins known as stabilizers are key components in maneuvering an aircraft, and much of the effort to develop stabilizers and their control surfaces was done during the 1800s when aviation pioneers such as Sir George Cayley of Britain and Alphonse Penaud of France began experimenting with models as well as manned gliders [1]
Summary
It is often a marvelous sight to behold when a modern airliner takes to the sky on its maiden flight. This is a result of cumulative engineering marvel after more than a century of flight. The typical airplane today still very much inherits the basic design concepts Cayley developed during the first half of the 19th century. While the fin-based stabilizers perform well even in supersonic domain, the shortcoming becomes apparent close to stall or in post-stall regimes in which aerobatic flights frequently operate. The shortcoming lies in the fact that a horizontal stabilizer and its elevator require sufficient
