    Real world PA-12 speeds

    My PA-12 has an O235-C with a max red line of 2600 and a Sensenich prop

    Iím getting:

    2300 static revs
    2350 in the climb at circa 65mph and circa 520fpm at about sea level
    2350 gives me 95mph straight and level
    2500 gives 110mph
    2600/wide open gives not much more than 110!!

    Do these numbers seem about right?!!

    Depends on what tires you have on it. 800 x 6 or bushwheels? makes a big difference! Wheel pants?

    Good to see that PA-12 in the air, remember it when it was based at Spanhoe. The speeds sound about right for a Cruiser on the original type engine. Around 5 mph more than a 90HP SC

    Those don't look like standard wheels. Sure they are not (ugh) 6:00x6?

    For a near-stock -12, I think the original poster's speeds are about right.

    Agreed, I think that's just about textbook. Mine will do 110 @ 2500...... if I push the nose down a couple hundred FPM.

    Mine has an O320 with a 74/50 climb prop. It seams to cruise right at 100mph on Federal 2000 skis at 2400rpm.
    My ROC is about double your numbers. When its on 8:00x6 tires its 105mph at 2400. It goes 93mph on 31" tires at 2400 with borer prop. I would like to try it sometime with a 74/56 cruise prop and the 6:00x6 tires
    as I am sure it would easily cruise over 110.......
    It has recent fabric , slippery paint and standard 12 fairings. However, this is a very light 150hp Cruiser at 1070lbs........
    . Hope that helps. Yesterday here on my lawn.

    Wow!!! Fantastic plane and house!!!!

    Apart from the ROC doesnít sound like a 320 makes a huge difference speed wise?

    LoL well thanks for the compliment, and its true, as Super Crow says, I like a nice paint job! Here is my last Cruiser, that I painted. It was on 2500 Airglass skis. Took a few days to mask it for two colors, the scheme was our design. We used to get tons of compliments on it. This one was about 5mph slower on 31's than the one I have now???
    Too many guys are so burned out by the time they finish the project they just slap a quick stripe down the side........
    20181217_172704~2.jpg I thought it looked nice on floats too!
