Nice!
That sounds good too huh?
YS-91 with a 13x12 APC? That would be awesome-
I have flown a TF P-51 that was equipped with a YS-120! Simply awesome performance, and SOUND!
Hadn't thought about the 4 cy.'s for all out speed - but what you lose in RPM's (Rossi, Jett, etc..) you make up with all that pitch....(?)
Now this thread should get interesting?
Whatever you decide- keep us posted so we can live vicariously through you!
