There are two basic types of horizontal stabilizer systems on most general aviation aircraft. Horizontal stabilizer with elevator, and or horizontal stabilator. If the horizontal stabilator system that is on most piper aircraft and some high performance fighter aircraft, then why are so many tailwheel and other aircraft designed with the horizontal stabs and elevator. Stabilator systems are supposed to be more effective and generally better by design. I am seeking opinions for an experimental aircraft that I am working on. It will be a tailwheel type aircraft.
