    Guys use the Aero-Matic. Not a controllable constant speed but close. Check the cessna 120-140 forum. Some of those guys are using them if i remember right.

    Ivoprop makes an electrically operated controllable prop (2 or 3 blade) but not approved for certificated airplanes as far as I know. I've heard MT makes or will be making an electrcially controllable prop also.

    Could you share with us any performance data? Do you have a much higher cruise speed? Any improvement in fuel economy? What about take off distance and climb?

    aeromatic prop

    I call ivo for a continental O 200 prop

    the prop that they sell was 68'' 2 blade Magnum

    68'' 2 blade is not good for floats

    i will be ordering a aeromatic prop this winter and i will post the performance information.

    I will retrieve my speed data from hangar today and post tonight. I had a mac7147 cruise prop before the aeromatic. My TC specifies max length of 73" for the aeromatic and i bought a F200-73 from Tarver Propellers. As i recall the cruise speeds are about the same but now the RPM's, out of the shoot, are 2620 instead of the 2390 that i got with the mac and that was what i was after because at gross wt. on an 85 degree day the 95hp needs all the boost it can get.

    yes reduction drive, There is an adapter that goes from 20 spine to a standard hub. Long props in constant speed are hard to find.

    DorianJ,

    Airspeeds with Mac 7147 and Aeromatic F200-73:

    2000 rpm 75 70
    2100 80 74
    2200 83 80
    2300 89 88
    2350 92 92

    these numbers are from my pa18-95 and the pull at 2300 was 375# with aeromatic.
