    I thought I recognized that voice. I'm surprised he (Josh) likes the Pietenpol that much, considering what the other videos Flitetest has put up are like. Many are frivolous. Some are amusing, such as, if you're in a silly mood, the Death Star video. OTOH, these guys deserve credit for building a business successful enough to pay for full sized flying. (Many assumptions in that last sentence, of course.) Maybe their general aviation videos will get a bunch of people interested in homebuilt airplanes.

    BTW, when he's in a turn, can a Piet pilot see ahead in the direction of the turn? Seems like the wing would block out a lot of space you'd rather see.

    Not much different than flying from the back seat of a Cub. Actually, being an open cockpit, I think the Piet may have a little better view into the turn compared to the Cub because you can tilt your head back and have a visual line of sight above the wing and into the turn.

    I'm willing to bet that a sky light in the center section of a Piet would probably be as much of an improvement as it is in the Taylorcraft. Never flown a Piet though, so this is all silly ramp talk opinion.

    They're around, all you need is a large amount of cash. They are not Continental A65 prices.

    A friend built one with a Ken Royce radial. It was sweet.

    Ahhh,well I guess off to find more economical variants of engines :)The Pietenpol has been mounted with many engines so I am not short of options.

    Has anyone ever used a Slant 6? I think it was supposed to weigh about the same as a Model A engine. Not sure about the dimensions. Also not sure if you can tilt it back upright so it doesn't look ridiculous. The torque curve I saw for it is quite flat. You can get almost full torque down to, as I recall, 1,300 rpm. For a short while, I had a3600 lb car in which the slant 6 engine was the only good part. I once put it in 3rd gear by mistake, and started up a slight upgrade without much trouble. Anyway, a spec I saw was 155 ft lbs at 2,400 rpm. That's a bit over 70 hp, though at higher speeds, different versions of the slant 6 were good for 100 to 145 hp. There was even a version with an aluminum block, though there are supposed to be very few left. The cast iron version is, of course, the engine that never dies.

    Those old sixes can be heavy. There was a Piet that flew with a Ford Fiesta engine and a clever reduction drive utilizing an AMC spindle and drm brake assembly

    I don't know how reliable the figures are, but the ones I've seen put the two engines at the same weight. The 6 has much more power than the Model A even at 2,400 rpm, so no need for a redrive. I guess with either engine there are aluminum goodies available to lighten them. Either one is a lot heavier than an aircraft engine, of course. Which Fiesta? The one from the '70's or this one?: https://youtu.be/TPf4qwtr8Fs?t=11s (the video is quite entertaining but off topic for this discussion). Or was there even another version?

    It was the Ed Lubitz conversion that used the Fiesta.

    When my daughter was just out of college I overhauled her Slant 6 and the little 914 auto trans. A very overbuilt engine and a simple good transmission. I don't know how much the slant 6 weighs but they are heavy. Didn't know there was a aluminum block version. One of the most reliable 6's made.

    A straight 6 has a long crankshaft. Could be an issue with a prop. Might need a flywheel at opposite end or something

    Model A is 200 cid or 3.3 L and weights about 300 lbs FWF with radiator and prop. Almost light weight. 40 HP. My guess, for "modern" as they are now old direct drive auto, would be Ford 3.8, Buick 3.8, or Buick 215 family, Buick 3.8 is really part of that family. I would pick the Buick 3.8 as the best of that bunch. Lots of performance parts to strengthen it up. The straight 6s are pretty heavy. The only straight 6 that would be close would be the early 170-200 Ford.
