Can't comment on tail-drag 'Queens, but the four on our Herrings when I was a rookie co-pilot sounded sweet enough from inside and outside. And we seemed to spend a great deal of time in cloud on our operation... Admittedly, they were the 250 HP version - a lot less powerful than the Dove's. What was it on the Prentice?
