I'm sure that even the Sabreliner was not intended for rolls
Funny that you should mention the Sabreliner
DAR, many, many years ago saw Bob Hoover put on a show at Dayton in the aircraft, rolled it as soon as the wheels were off the ground on take off, raised gear on completion then proceeded with a display that included every aerobatic maneuver you could imagine save for a spin, included a vertical climb into a tail slide before pitching over (I mean pitch, not stall turn), engines didn't seem to complain with the air flow coming from 180°.
Still had it at 91 years of age.
