Ok, sorry for jumping on you, actually likening you to Crumpp was probably the most insulting thing for which I am most regretfull, I have to admit my mistake was not thinking 10 foot diameter props.....goes to show how your own experience can get you stuck in a rut sometimes, I fly a Stearman with a 7 foot and a bit prop and 1500 rpm is practically idling, the R-670 engine has no reduction drive.
