With that said - when you get the gear leg and intersection fairings installed you will see a very nice increase in cruise speed! One note I would suggest that you install your main gear fairings first and fly. You can then install the nose wheel fairing and may avoid a rudder tab, if needed.

I have been flying a constant speed up to now, but it has become uneconomic to maintain/repair. I am going to try lighter/simpler for a change, so I'm looking for a wood prop suitable for a 160hp O-320. Any recommendations based on actual operational experience would be appreciated. Also, if you know of one currently for sale please let me know. Thanks, Eric erwhites@bellsouth.net Eric: I have learned to distrust dogmatic statements and assertions that resemble dogma. Nevertheless some generalizations are reasonably useful. Metal props, being thinner, are likely more efficient than wood ones. Would you consider a fixed pitch metal? What will a wood prop do to your CG? Is the CG change acceptable? What do you want the prop to do; max speed at sea level and 2700, max speed at 10000' and 2700, best cruise at mid levels and some intermediate rpm, best initial takeoff and climb ability, greatest ground clearance, best cruise at high altitudes? There are a good many more questions. Do you expect to fly in rain? Will you have strong alternating high humidity/low humidity cycles? How clean is your airplane (there's a doozy of a question}. My direct experience is with Sensenich props. Their method of measuring pitch is different from some others but they do make props to a standard that they can reproduce. Consequently they will not alter a prop since that creates a non standard unit. I can send you performance data that was taken from my 160hp RV-4 but it would be useful only as a guide. Attached you your airplane it could be altogether different. Some years ago when considering a prop for my -4, I spent some time at Oshkosh with a couple of steel scales, measuring props. The variation was astonishing. Many that I looked at from reputable makers varied greatly from blade to blade. Does it matter? Maybe not very much but it moved me toward Sensenich. I have also learned that the surface condition is very important, causing performance variations of as much as 5%. Contact me off line if you would like to continue this conversation.
