Group,

Two different questions. Looking for your input.

#1

Flew my S1S with an O-360 180hp and swinging a metal Sensenich prop
76-56. This combination has always been easy to overspeed the engine.
On climb out at full throttle I have to maintain 85 mph indicated or
it will exceed 2700 rpm. In cruise it only takes 1/3 to 1/2 throttle
to maintain 2700 rpm in level flight. At full throttle it will hit
3100 rpm. To me it seems like it's underproped. I am thinking of
going to something with more pitch, like a -58 or -60. What do you
think?

#2

Since I am thinking of a prop change I have also considered going to
wood. Specifically a "Performance Propeller" wood two bladed. I have
heard all the advantages/disadvantages over the years and just
wondered if anybody has some real world experience with their pitts or
similar.

Many thanks for input/feedback.

Gus
