Currently there is a McCauley 1b90 CM 7445 stuck onto the front of my BC-12D. My son and I have been talking about trying to put a landing in each of the lower 48. Just an idea with lots of things to think about. One item is changing the propeller to more of a climb prop. To save a little weight we were thinking of changing to wood. Besides the extra maintenance can you guys share pros and cons of choosing wood? Does a lighter prop spin up faster giving better climb even with a slightly steeper pitch?

The Mac 7445 is a compromise prop, i.e. good on all fronts but not fantastic at any of them (jack of all trades, master of none, if you will). But for that reason it is highly useful & desirable & valuable.
A wood prop will not perform as efficiently, and may be damaged by rain.
In my 65hp Taylorcraft (albeit with a Sensenich metal prop) I have flown all the lower 48 since 2015 (despite living in the UK and the lack of transatlantic travel in the last two years). So I'd suggest you stick with what you've got.
(As an aside, all new Mac fixed-pitch metal props are made by Sensenich!)
Hope that helps;

Gary, I believe this is too short, should be 76" long for a great climb prop....TimOriginally posted by PA1195 View PostN29787

That is a damn good prop including the pitch. No matter if you are doing ALOT of cross country I would stick with a metal prop. Just one man's humble opineComment

Stay with the Mac 7445! Or else I'll offer a ridiculously low price to take it off your hands!Comment

The unfortunate truth is that while the wood props look nice, are lighter, and run smoother on the engine, they are simply not as efficient as the metal prop. Until the FAA finally allows a newer more efficient wood prop to be used you will have to determine whether you want the best performance or the niceties of a wood propeller.Comment

Rob, I see that there are two separate threads on the same subject. Maybe you could merge the post into one thread.Comment

Cor blimey, it's so long since I've had to do that I don't know if I can remember how! I'll give it a go: standby oblivion!Originally posted by 3Dreaming View Post

Sorry about the duplicate post. After clicking Post Reply I got an error message saying there was an issue posting the reply. I re-sent it twice more, hence the three posts. Thanks for deleting two of them.
Mea culpas aside: thanks for the replies and help as we get up to speed with the airplane. We can fly this prop for the summer and then make a determination of it's better to change the pitch. Replaced the skis with the wheels a few days ago and the strip is almost dry enough to fly.Comment
