May 24, 2019 at 18:05 comment added Zeiss Ikon @RobertDiGiovanni But if you go too slow, the cat will be waiting Which is probably why most of the Hill AFB crashes I recall (from the period my parents lived in that area) were on landing or takeoff. Lose fly-by-wire at 50 feet at 20 kt above stall, and you've got a problem...
May 24, 2019 at 17:55 comment added Robert DiGiovanni +1 for your answer. You can set up a model to be "staticly unstable (in pitch)" as long as it is still DIRECTIONALLY stable (aerodynamic nuetral point is usually well behind the CG). The elevator is trimmed down. These models have an interesting property of "altitude or speed stability" because the increasing aerodynamic pitch down is cancelled by increasing lift trying to make the plane climb with increasing speed. But if you go too slow, the cat will be waiting.
