YS 140 Sport - Too much for Swallow?
HI,
I've engined my Swallow with both an OS 91Fx and a YS FX110. No question in my mind, the YS is the one for this plane. Even using an OS1.60 header, pipe and perry pump, the OS didn't pull in the vertical's like the YS, and doesn't fit the plane very well (Eg. the cover over the header won't fit.
The 110 is just a joy in this plane.
