Anyone have any experience with this engine? I have seen the larger ones in use but not the 51. George
I have very little experience, but as I recall, we did an emergency pipe conversion (at a contest) on one, and set it up much like a 40VF, except with a bigger prop. It ran that way acceptably well (given that the header muffler had fallen apart, anything is better than DNF) but no promise that it was optimal. 17,5, Bolly 11.5-3.5 3-blade - but bear in mind this was A LONG TIME ago.
