    Re: 0-200 prop

    Thanks Tim

    I'm still a few months away from engine installation and will do when I get to that point. I agree, the pitch is quite agressive in comparison with the reccomended and if I had bought a prop, I would propably just have stuck with the reccomended.
    Was just wondering if anyone has experimented with something like that.
    If i'm the first then I'll post my findings once I get to that point

    check your static rpm, I think you have too much pitch. Tim

    Hi Everyone

    I got my unfinished project (ZS-VHL) with a 7157 mcCauley prop (brand new). It is a '46 BC-12D that will get an O-200 engine. It will be non type certified.

    I know for a fact that the aircraft engine and prop has never been togeteher before.

    We are 4500 ft AMSL

    My question: Can this prop be safely used??

    Mine would easily static around 2500 and would easily redline in level flight and go no where, about 115 and felt sluggish in the air if you pulled power back

    Check the tach first. Or use a master tach instrument pointed at the prop.

    I am running a 7443, it can easliy over rev in level flight...and a 7538 will really climb....on an F-19 on floats. Tim

    If you're after low-end pull -- go long and flat -- 7440.

    If you're after speed -- go short and coarse -- 7146.

    Don't cut a good 74 inch 1B90 to 71 inches. They're too hard to find... sell it and by a 71 inch prop, use the difference for gas.

    I flew the test flights and have written those up many times..... the 69-50 was off my Cessna 150 ; IT worked , Dorothy bought one. The 74-43 was the "seaplane" prop ; NOT my idea! It worked ; Dorothy bought one.

    It will turn redline and only 2 props are approved for the F-19, 74-43 or 69-50

    74-43 is too flat for me, really needs 2 more inches. 69-50 flies fine, but climb definitely suffers. You will be able to find the shorter one more readily available

    started a topic 0-200 prop

    0-200 prop

    Looking for a prop for my 0-200 on my F-19, I have searched the ATC 1A9 and see the McCauley 1A105/ SCM 6950 and the 1B90/CM 7443 are recommended. Just wondering what guys that are flying with a 0-200 have had the best results with. Also if anyone has one for sale.
