Cessna 180 K--Switch from O-470U withC204 90" two ...
Bill Hall
Anybody have experience with the subject matter??  I.e. an engine change on a 1977 C180 K model with Cont O470U engine and Mac 90" C204 prop to a Pponk O470-50 with a three blue prop??
I am leaning toward at the Hartzell three blade option.   Opinions welcome.   What sort of performance expectations should I have?  I'm interested in improved cruise without sacrifice to take off/landing performance  and hopefully without noteworthy increase in fuel burn at cruise.
Any thoughts on Hartzell versus MacCauley three blade prop options??
