Hoover's flying is superb, and the reason his show is so impressive (without being terrifying) is that it is sooooo smooth - He knows his survival depends on keeping the airplane in the regime where airplane/control response is approximately linear. I believe the only airplane he spun in shows was the NAA F-86 Sabre.
As well-thought-out is the dead-stick Shrike Commander routine, his P-51 show closer (touchdown on the numbers - pullup and roll - land & stop on the remaining runway) is REALLY convincing.
